256 THE VOYAGE OF H.M.S. CHALLENGER. 



Shell. — Fusiform, strongish, pale buff, with a high blunt spire, largish mouth, slightly- 

 reverted outer lip, and four teeth on the pillar. Sculpture: Longitudinals — on the 

 upper whorls there are a few slight narrow ribs which are almost obsolete on the later 

 whorls ; the lines of growth are many and hair-like. Spirals — quite obsolete. The 

 columellar swelling in front is very small and slight. Colour ashy white over pale buff, 

 entirely without gloss, the outer lip and the body-glaze are rich buff, paler inwards. 

 Spire high, a little irregularly bent, subscalar. Apex blunt, mamillary, impressed. 

 Whorls 6f : they are convex, above contracted into the suture, perpendicular below ; 

 after the first three they increase rapidly ; the last is slightly ventricose, long, attenuated 

 in front. Suture oblique, slightly impressed, irregular. Mouth long, but not wide, 

 oblique, with its two sides nearly parallel, bluntly pointed above, ending below in a 

 broad, shallow, slightly emarginated, minutely bordered canal. Outer Up patulous, thin, 

 but expanded and rounded on the edge ; it rises on the penultimate whorl at its junction, 

 and is here drawn back into a slight sinus with a very reverted edge. Inner lip spreads 

 widely as a thin glaze on the body ; above it is scarcely convex, hardly concave in the 

 middle, perpendicular below, where are four not strong, equal, concealed, pale-coloured, 

 very oblique teeth ; obliquely cut off, twisted and rounded in front into a prominent 

 thin point. H. 275 in. B. L25. Penultimate whorl, height 0-53. Mouth, height 173, 

 breadth 0"6. 



This species is suggestive of many others, and may be compared with Voluta rupcstris, Gm., 

 Valuta pacifica, Sol., Voluta lyriformis, Vigors, and Voluta fulminata, Lam., but resembles most 

 Voluta megaspira, Sow., having the same long thickened lip and form of body-whorl ; but in that 

 species the spire is higher and is fine, and the apex is tumid.
