Other material examined. – Pfeiffer’s examined specimens of var. β from Borneo (?) or China (?): BMNH 19601542.1 (2 S shells, Fig. 1 C – E). Singapore: ZMB, Paetel coll. (1 S shell); RMNH # 19 a (1 D shell); BMNH 98.10.25.131 (2 S shells). Singapore or Borneo: RBINS Dautzenberg ex. Crosse coll. (1 D shell), Dautzenberg coll. 6990 (1 D shell). Java: ZMB Seckendorf coll. (1 D shell). Unknown locality: ZMB Bürger coll. (1 S shell), Wallenberg coll. (1 S shell); RBINS Dautzenberg coll. # 6990 α (1 S shell); ZMUC # 295 (2 S shells). Taxonomic remarks. – The nominal species “ Bulimus mundus ” was described from “ Gruner’s collection ”. After his death, the collection was sold and the most part was purchased by H. Maltzan, whose collections are currently housed in Aquazoo-Löbbecke Museum in Düsseldorf. However, some of Gruner’s specimens are also extant in other museums including SMF and ZMB (Tëmkin et al. 2009: 44). After a long investigation, the original type series of “ Bulimus mundus ” from “ Gruner’s collection ” was not located, and is presumed to be lost (M. Glaubrecht, R. Janssen, B. Hausdorf, R. Seemann and S. Stoll, personal communication). The absence of type material of the nominate form has been the cause of doubt about the identity and status of this species (Laidlaw & Solem, 1961). We consider that the specimen of Bulimus mundus var. β cited by Pfeiffer (1853 a) from the Cuming collection, is an example of this species but having been identified by Pfeiffer as a variety, it was excluded from the original type series of Bulimus mundus. Because of the uncertain origin of this lot according to the label information (‘ Borneo? ’ and ‘ China? ’), the form β is deemed unsuitable for designation as a neotype. The neotype selected here from our Pulau Besar collection allows a proper re-description of this taxon with the aim to stabilise the taxonomy.	en	Sutcharit, Chirasak, Panha, Somsak (2011): Neotype Designation And Re-Description Of The Vanishing Tree Snail, Amphidromus (Amphidromus) Mundus (Pfeiffer, 1853) (Pulmonata: Camaenidae).

215887E3BA08FFA0FF62FEEB3A239B45.taxon	description	Description. – Shell (Fig. 1 A): Medium sized to small, (height 32.7 – 40.3 mm, diameter 19.3 – 23.8 mm) white, solid, ovate conic; umbilicus perforate; chirally dimorphic. Apex acute; spire short; suture depressed. Whorls slightly convex; last whorl round to ovate. Dark varix absent; periostracum thin and transparent. Aperture broadly ovate. Lip thickened, expanded and reflexed but not attached externally to last whorl. Parietal callus thickened; columella twisted. External anatomy (Fig. 1 B): Living specimens with pale brown body, covered with darker recessed reticulations on skin. Foot broad and long with pale margin, extended across posterior tail. Upper tentacles drumstick-shaped, orange-brown, with dark eyespots on tentacular tips. Lower tentacles short, orange to pale orange; head and mouthparts brown. Mantle edge light orange; mantle cavity with dark pigmentation. Genital anatomy (Fig. 2 A): Atrium (at) relatively short (n = 5). Penis (p) cylindrical, about ¾ of vagina length, and enlarging slightly distally. Epiphallus (e) long and slightly smaller in diameter than penis. Flagellum (fl) almost the same length as epiphallus with coiled distal portion. Appendix (ap), located beyond coiled portion of flagellum, nearly same length as flagellum. Vas deferens (vd), a narrow tube, extending from free oviduct ending at epiphallus. Penial retractor muscle (pm) long, thin, originating distally from penis, attached to penis near distal end. Internal wall of penis corrugated, exhibiting series of thickened, swollen, longitudinal penial pilasters (pp), which form a fringe around conical penial verge. Penial verge (pv) short, conic with smooth surface (Fig. 2 B). Vagina (v) long, slender and cylindrical. Gametolytic duct (gd) extends from vagina, proximally as enlarged cylindrical tube, abruptly tapering to small tube distally, terminally connected to gametolytic sac (gs). Free oviduct (fo) short, oviduct compact and enlarged to form lobule alveoli. Prostate gland ventrally fused with oviduct. Albumen gland (ag) slightly large and lingulate. Hermaphroditic gland (hg) contracts from numerous small lobules; narrow and convoluted hermaphroditic duct (hd) connects to middle of talon (Fig. 2 A). Internally the vagina possesses longitudinal vaginal pilasters (vp). Pilasters have continuous ridges with short smooth ridges near genital orifice; extends to slightly swollen portion with irregular shaped, deep crenellations (Fig. 2 B). Digestive anatomy (Fig. 2 C, 2 F): Jaw light brown and corneous with strong vertical ridges. Radular teeth arranged in anteriorly pointed V-shaped rows, each row containing about 206 teeth (102 - (17 - 15) - 1 - (15 - 17) - 103). Central tooth tricuspid, spatulate, with small ectocones (Fig. 2 D). Lateral teeth bicuspid, endocone large with truncated cusp, ectocone larger with curved cusp. From tooth 15 to 17 outwards lateral teeth gradually transformed to tricuspid marginals (Fig. 2 E). Marginal teeth asymmetric, endocone medium; mesocone large with curved margins; ectocone small.	en	Sutcharit, Chirasak, Panha, Somsak (2011): Neotype Designation And Re-Description Of The Vanishing Tree Snail, Amphidromus (Amphidromus) Mundus (Pfeiffer, 1853) (Pulmonata: Camaenidae).

215887E3BA08FFA0FF62FEEB3A239B45.taxon	distribution	Distribution. – The confirmed distribution of this species is currently restricted to the type locality, Pulau Besar, Johor, Malaysia. Species determinations of samples from museum collections with records from a numerous localities, such as Singapore, the Philippines, Borneo and Java (Laidlaw & Solem, 1961: 589; S. Panha, personal observation in collections) require verification. Occurrence in China, as given on the label of ' B. mundus forma β’ cited above, can be ruled out with certainty because China is outside of the geographic range of Amphidromus (Solem, 1959, 1983; Laidlaw & Solem, 1961; Sutcharit & Panha, 2006 a).	en	Sutcharit, Chirasak, Panha, Somsak (2011): Neotype Designation And Re-Description Of The Vanishing Tree Snail, Amphidromus (Amphidromus) Mundus (Pfeiffer, 1853) (Pulmonata: Camaenidae).
