            <p> Synonymy. “Unidentified narcomedusa” in Raskoff et al. 2005. “Narcomedusa” in Holland 2006. “New Narcomedusa” in Raskoff et al. In press. “  Narcomedusae sp. nov.” in Kosobokova &amp; Hopcroft In press. “new narcomedusa” in Bluhm et al. In press. </p>
            <p>Type material. The holotype and four paratype specimens have been deposited at the Smithsonian, National Museum of Natural History, Invertebrate Zoology Collection. USNM 1125360 Holotype, station 5, Canada Basin (73º 22' N; 153º 36' W), 4 July 2005 at 1607m depth. USNM 1125361, Paratypes, station 8, Canada Basin (74º 34’ N; 151º 56' W), 11 July 2005 at 1514 m depth; four specimens.</p>
            <p> Etymology. The generic name  Bathykorus references the habitat and shape of the species. Bathy (Greek; from bathus, depth or deep) refers to the deep-sea habitat of the species, and korus (Greek; helmet) refers to the helmet-like shape of the bell. The specific epithet of  bouilloni is named in honor of the late Dr. Jean Bouillon, (1926–2009). Dr. Bouillon’s studies spanned over 60 years, and described 17 families, 34 genera, and 114 species. His work and his generous sprit continue to enlighten and inspire generations of biologists. </p>

            <p> Bathykorus bouilloni sp. nov.</p>
            <p>Bell. The medusae shows primarily tetramerous symmetry with the umbrella being dome-shaped and the apex having a pronounced thickening of the mesoglea; with a maximum observed diameter of 1.5cm and height of 1.1cm (Figure 1). The mesoglea becomes thinner at the margins and has a uniform light blue coloration in life which turns milky-white when preserved. The bell is incised or lobed below the origin of the primary tentacles forming the peronia (Figure 1 D). There is a thin velum on the inside edge of the umbrellar margin.</p>
            <p>Tentacles. There are four primary, solid, noncontractile tentacles which originate above the umbrellar margin and peronia (one specimen of 25 collected was found with five tentacles) that are two to three times as long as the medusa is wide. These primary tentacles have deep endodermal tentacular roots that anchor into the mesoglea through the exumbrellar surface (Figure 1 E). On the margin of the bell there is one secondary tentacle per quadrant hanging free from the edge of the lappet (one specimen was found with two secondary tentacles in a single quadrant) (Figure 1 C&amp;D). The core of the tentacles is made of very large vacuolated endodermal chordal cells (Figure 2 A&amp;B).</p>
            <p> Subumbrella. The mouth is simple and circular, but can fold into irregular patterns with muscular movement. The mouth extends into a wide and flat gastric cavity that leads into the interradial manubrial pouches, a feature characteristic of the  Aeginidae . There are typically three manubrial pouches per primary tentacle (Figure 1 D), although one specimen was observed with four pouches in one of its quadrants. There are an equal number of simple canals to the tentacles (usually four) which quickly bifurcate into the peripheral and peronial canals which follow along the margin of each interradial lappet. It was not determined if the canals are hollow, or solid as is common for some  narcomedusae . </p>
            <p> Statocysts. There are typically two free hanging, ecto-endodermic statocysts found in each quadrant, one on each side of the secondary tentacle. In one specimen there were two secondary tentacles in a quadrant and there were three statocysts, alternating with the tentacles. The statocysts have 5–7 statoliths in each cluster (Figure 1 B). They appear to be similar to the “closed” marginal sensory clubs found in  Sigiweddellia benthopelagica (  Cuninidae ; Bouillon et al. 2001), but it is unclear based on their drawings and description. In  Bathykorus bouilloni the hanging statocysts are not found within distinct pockets in the ectoderm, as is seen in  S. benthopelagica . </p>
            <p> Cnidome. Cnidocysts are found in an asymmetrical pattern on the main tentacles such that the dense collection of cnidocysts are on the aboral (exumbrellar) side of the tentacles (Figure 2 A&amp;B). This is the side that would contact prey when the tentacles are held aloft in their typical foraging position. There were very few cnidocysts found on the oral side of the tentacles. The cnidome mainly consists of two different sizes of cnidocysts, with two major size fractions of nematocysts found, as is typically described for other  narcomedusae (Carré et al. 1989; Purcell &amp; Mills 1988) (Figure 2 C&amp;D). Both of these nematocyst types appear to be apotrichous isorhizas. The large macroisorhizas had a diameter of 22.6 µm ± 0.44 (Mean ± SE; N=65), while the smaller sized microisorhizas had a diameter of 8.3 µm ± 0.19 (Mean ± SE; N=40), with these differences (Figure 3) statistically significant (P = &lt;0.001) using a Mann-Whitney rank sum test. </p>
            <p>Gonads. Although 25 specimens were examined, no obvious mature gonads were observed under a dissection microscope at up to 100x magnification. Although some thickened, dense tissue was found in the distal area of the interradial manubrial pouches, no definitive determination was made of its type. Either the population was immature at this time of the year, or the gonads are not obvious and a careful compound microscopic exploration is needed.</p>
            <p> Discussion. Modification to  Aeginidae</p>
            <p> The family  Aeginidae is now modified to include species that have between one and four interradial manubrial pouches between each primary tentacle. A new diagnosis and key to genera, based on Bouillon et al. 2006, is provided. </p>
