jrOLLUSCA OF THE ' CnALLEJiTGER ' EXPEDITION. 327 



111 this specimen the folds on the pillar-lip are more distinct than 

 on the Heard-Island specimen. 



There is an Admete from St. 149 c, Kerguelen, Eoyal Sound, 

 60 fms., which is too much Ijroken for identification, but which is 

 probably this species. 



3. Cancellaeia (Admete) carinata, n. sp. 



St. 149 d. Jan. 20, 1874. Lat. 49° 28' S., long. 70° 13' E. 

 Eoyal Sound, Kerguelen. 28 fms. Mud. 



Shell. — Broadly ovate, carinate, spiralled, with a very short, 

 blunt, scalar spire. Sculpture. Longitudinals — there are only 

 fine, sharp, unequal puckerings on the lines of growth. Spirals — 

 a sharp flanged keel lies about the middle of the whorls ; above 

 this is the horizontal, slightly concave shoulder, on wliich are no 

 spirals ; below the keel the whole surface is scored with fine 

 prominent rounded unequal threads, parted by broader intervals ; 

 those on the snout are feeble. Colour white. Spit'e very short 

 and depressed, but rising in broad shallow steps. Apex small, 

 raised. Whorls 5, flattened or even slightly concave above, 

 strongly keeled and angulated in the middle, of regular increase; 

 the last is very large and ventricose, with an elongated but convex 

 base and a very small snout. Suture impressed, very horizontal. 

 Mouth fully half the size of the shell, oval, angulated at the keel 

 and at the base of the pillar. Outer lip rounded and open, advan- 

 cing a little in front of the point of the pillar. Inner lip thinly 

 spread ou tlie body, with a small cliink in front behind the pillar, 

 the edge of which is narrow and twisted, with two indistinct folds 

 above it. H. 04. B. 0-28. Penultimate whorl, height 0-07. 

 Mouth, height 0-3, breadth 017. 



I failed to extract the animal from the shell; but plainly it had 

 no operculum. The extreme bluntness and tabulation of the spire 

 give a very peculiar aspect to this species.
