            <p> Genus  Gollum Compagno</p>
            <p> Gollum Compagno, 1973 , Proc. California Acad. Sci., ser. 4, 39(14): 264. Type species:  Triakis attenuata Garrick, 1954 , by original designation. </p>
            <p>Definition. Distinctive carcharhiniform sharks with a firm to soft and very slender body; short, bell-shaped head; long, flattened snout, horizontal length 7–9% TL; small spiracles, 4–10 times in eye length; angular mouth with very small multicuspidate teeth (81–114 rows in jaws); dental bands comb-like near jaw angle; moderately elongate labial furrows (lower furrow subequal to or greater than length of incurrent aperture of nostril); short anterior nasal flaps (subequal to length of excurrent aperture of nostril); broad internarial space, 1.5–1.9 times nostril width; no dermal gill rakers or large oral papillae; first dorsal fin not long-based and keel-like; interdorsal ridge present; first dorsal-fin base well forward of the pelvic-fin base; second dorsal fin taller and more upright than first dorsal fin; anal-fin origin well behind second dorsal-fin origin; free rear tip of anal fin under or slightly forward of second dorsal-fin insertion; no precaudal pits; caudal peduncle relatively elongate, 8–10% TL; dorsal caudal margin short, 19–23% TL, not undulated, instead with a raised scaly ridge; enlarged lateral scales of caudal ridge semicircular, horizontally directed; coloration simple, darker dorsally than ventrally; monospondylous centra 44–53, diplospondylous centra 107–113, total centra 151–166.</p>
            <p> Species.  Gollum attenuatus (Garrick, 1954) ,  G. suluensis sp. nov.</p>
            <p> Remarks. The erection and initial placement of  Gollum in the family  Proscylliidae followed Compagno (1973), and was subsequently assigned to a new subgenus Golluminae (Compagno, 1988). However, in more recent studies (Compagno 1999; Compagno et al., 2005a, 2005b) it has been relocated to the related carcharhiniform family  Pseudotriakidae .  Gollum differs from the three proscylliid genera (i.e.  Eridacnis Smith ,  Proscyllium Hilgendorf and  Ctenacis Compagno ) in having a deep notch on the lateral margin of the snout forward of the nostrils giving the head a bell-shaped appearance (rather more evenly rounded) when viewed dorsolaterally, and lacking gill rakers and oral papillae (Compagno, 1988). It shares the family  Pseudotriakidae with the monotypic genus  Pseudotriakis Capello , which differs from  Gollum in having a soft stocky body (firmer and more slender), a very long, keel-like first dorsal fin (relatively taller and much shorter based), and a much shorter caudal peduncle. </p>

            <p>Size. Small shark reaching at least 652 mm TL and 2.0 kg (female); smallest adult male 580 mm TL.</p>
            <p>Distribution. Known only from off Palawan Island (Philippines) in the western sector of the Sulu Sea basin; collected on the insular slope at about 730 m depth.</p>
            <p> Etymology. Named in reference to the Sulu Sea, an important marine region of the southern Philippines with a rich biodiversity, which is also the type locality of this shark. The epithet ‘suluensis’ established here has been used previously in combination with  Gollum in biodiversity lists (i.e. Global Biodiversity Information Facility Data Portal and Global Names Index, GBIF, 2011), presumably based on holdings of the museums and collections web site for Philippine specimens. However, prior to its use herein, the name was not available (nomen nudum) as it failed to meet requirements of Article 13 of the code International Code of Zoological Nomenclature, 1999 (i.e. lacking a definition or description, as well as a designated type specimen). </p>
            <p> Comparisons.  Gollum suluensis differs from  G. attenuatus in having an overall darker and plainer coloration when fresh. The dorsal surface is less strongly contrasted, particularly around the head where the lateral demarcation of a dark dorsal surface and a whitish ventral surface are abrupt in  G. attenuatus (often less obvious in preserved material). Also, the tips of dorsal fins are darker than the fin base in  G. suluensis (not appreciably so in  G. attenuatus ), the ventral margin of the caudal fin is dusky and not strongly contrasted with the rest of the fin (rather than whitish and very strongly contrasted), and the mouth is dark (rather than pale). Also, the body of  G. suluensis tends to be softer and more flexible than  G. attenuatus . </p>
            <p> These species also differ substantially in several morphometric characters: length proportions around the head of  G. suluensis are typically smaller than in  G. attenuatus (horizontal preorbital length 7.1–8.1% vs. 8.5–9.3% TL, prenarial length 5.9–6.4% vs. 7.4–7.8% TL, preoral length 7.9–8.5% vs. 8.7–9.3% TL); head and associated structures of  G. suluensis relatively broader (head width 12.0–14.3% vs. 9.9–10.7% TL, mouth width 8.8–9.7% vs. 7.6–8.0% TL, nostril width 2.4–2.7% vs. ~2.1% TL); the spiracle of  G. suluensis smaller (spiracle length 0.4–0.8% vs. ~1.0% TL); the pectoral fin is larger in  G. suluensis (pectoral posterior margin 11.6–12.3% vs. 9.3–9.7% TL, pectoral base 5.3–5.9% vs. 4.6–4.8% TL); the first dorsal-fin base slightly smaller 9.3–10.0% vs. 10.3–11.1% TL); and the upper lobe of the caudal fin is relatively longer in  G. suluensis (dorsal caudal margin 21.9–22.8% vs. 20.3–20.7% TL) but the lower lobe is shorter (preventral caudal margin 6.3–7.3% vs. 7.6–8.0% TL). </p>
            <p> Morphometric differences discussed above are best demonstrated by the following non-standard ratios: preoral length/mouth width 0.82–0.96 in  G. suluensis vs. 1.08–1.22 in  G. attenuatus ; spiracle length/eye to spiracle 0.29–0.71 vs. 0.81–0.91; preoral length/prenarial length 1.27–1.33 vs. 1.18–1.20; eye length/nostril width 1.40–1.50 vs. 1.82–1.89; head length/nostril width 8.00–8.96 vs. 10.25–10.91; prenarial length/subterminal caudal margin 1.61–2.14 vs. 2.81–2.86; direct snout length/interorbital space 1.20–1.38 vs. 1.66–1.83; dorsal caudal margin/preventral caudal margin 2.98–3.63 vs. 2.60–2.66; length of first dorsal-fin base/dorsal caudal margin 0.41–0.46 vs. 0.50–0.55; and internarial space/nostril width ~1.47 vs. 1.82–1.91. </p>
            <p> They also differ in vertebral counts: monospondylous centra 44–45 in  G. suluensis vs. 50–53 (n=5, based on 4 new specimens (NMNZ P 5724, P 7351, P 39440, and CSIRO H 6077–05) and a specimen from Compagno, 1988) in  G. attenuatus , dorsal precaudal centra 97–101 vs. 105–111, ventral precaudal centra 94–99 vs. 107–113, diplospondylous centra 107–109 vs. 111–115, total centra 151–154 vs. 162–168. </p>

Gollum attenuatus was initially known only from New Zealand seas (Garrick 1954, Compagno 1988) where it has since been collected widely using bottom longlines; north to the Wanganella Bank (32°35’S) and the Three Kings Ridge (28°10’S) (Yano, 1993a), and south to at least the Snares Islands (48°54’S) (Yano, 1993b), where the primary depth interval for more than 750 specimens was from 500–600 m (Yano, 1993b). More recently, material was collected during French exploratory surveys around New Caledonia (Séret, 1997), and later in 2003 during the NORFANZ voyage, an internationally funded survey of the Lord Howe Rise and Norfolk Ridge (Williams et al., 2006). </p>
            <p> While making a quick comparison of material held in Paris, Séret and Last (unpublished data) noted some minor coloration differences between preserved specimens of  Gollum attenuatus from New Zealand and material collected further north of New Caledonia. Garrick (1954) originally described his  Triakis attenuata as being ‘generally brownish grey, but lower surface of trunk, pectorals and caudal, and distal portions of the other fins greyishwhite’, and old material from New Zealand held at the MNHN and NMNZ fit this general description (see Fig. 1 B). The more recently collected material from New Caledonia and the Norfolk Ridge have a strongly contrasted dorsal and ventral coloration with significant patches of white on the fin margins, and a prominent dark bar near the posterior margin of the caudal fin (see Fig. 1 C). Based on Séret and Last’s provisional findings, Compagno et al. (2005) treated these colour variations as separate species, referring to the New Caledonian form as  Gollum sp. B. However, further inspection of available material by the senior author indicated that differences between these forms are more likely to be due to artifacts of preservation. The same material from New Zealand, when immersed in preservative, retains evidence of these distinctive contrasting pale and dark areas on the body and fins, including the caudal bar. Nonetheless, more work, particularly with the aid of molecular methods, is needed to be conclusive. </p>
            <p> Nothing is known of the biology of G. s u l u e n s i s but it may have a similar habitat, reproductive strategy and food habit to its congener.  Gollum attenuatus matures at about 700 mm TL in both sexes (Yano, 1993a) and reaches 1092 mm TL (Yano, 1993b). It usually has a litter size of two. Each ovum produces ca 50–100 ova, of which ca 30–80 are enclosed in an egg capsule. Only one embryo develops in each capsule, and the undeveloped ova are ingested and passed to an external yolk sac that produces nutrition for the developing embryo (Yano, 1993a).  Gollum attenuatus lives near the bottom and feeds mainly on fishes (small sharks and teleosts), as well as small benthic invertebrates (Yano, 1993b). </p>
