KEPOET ON THE GASTEEOPODA. 209 



canal. Outer lip thin and sharp, slightly sinuated above, rounded and prominent in the 

 middle, and retreating along the canal. Inner lip flat above, concave at the base of 

 the pillar, which is straight, longish, conical, and obliquely cut off in front : a thinnish 

 narrow, sharply-defined pad of glaze extends along the whole length of the lip. 

 Operculum, sub triangular, with the apex at the lower inner point, thin but strong 

 brownish yellow. H. 1-55 in. B. 0'6. Penultimate whorl, height 0"28. Mouth, height 

 078, breadth 033. 



This species greatly resembles Fusus (Sipho) kroycri, Moller ; but ,is smaller, and has a con- 

 traction below the suture absent in that ; the whorls are less tumid, the longitudinal ribs are much 

 smaller and less curved ; the lines of growth correspond with the ribs instead of cutting obliquely 

 across them ; the spiral sculpture, too, is more raised and less regular. The apex in the Challenger 

 specimen is somewhat eroded, but is distinctly more cylindrical, the first and second whorls being 

 much more nearly equal than in Moller's species.

Station 149c. January 19, 1874. Balfour Bay, Kerguelen. 20 to 60 fathoms. Volcanic 

 mud. 



Station 149d. January 20, 1874. Royal Sound, Kerguelen. 28 fathoms. Volcanic mud. 



Station 149f. January 27, 1874. Rhodes Bay, Kerguelen. 95 fathoms. Volcanic mud. 



Station 149j. Off Cumberland Bay, Kerguelen. 105 fathoms. Volcanic mud. 



Habitat. — Kerguelen Island, 120 fathoms (v. Martens). 



The operculum of this species is not that of a Euthria, being long, pointed, and with a subspiral 

 nucleus ; the radula, however, is still more unlike that of Sipho. I am, therefore, content to follow 

 v. Martens' classification ; though the canal of the shell is not long and can hardly be said to be 

 recurved.
