KEPOKT OjS t THE GASTEROPODA. 207 



The general aspect of this shell is very much that of a Fasciolaria ; but the pillar has no plaits. 

 It is not in form unlike the young of Fusus rostratus, Olivi ; but the base is much longer, and the 

 snout shorter, and the constriction at the bottom of the whorls is not found in that species ; in these 

 respects it has more resemblance to Fusus syracusanus, Lam., in which, however, the whole 

 sculpture is very unlike. It resembles perhaps most of all Fusus JUosus, A. Ad., from the Chinese 

 seas, but is still slimmer in its outlines. 



I had called this species after my friend Mr W. H. Dall, of the Smithsonian Museum, 

 Washington, but Mr Friele of Bergen seems to have run me close in the friendly thought, 

 and has called another species of Neptunea by the same name. Both species were published 

 in 1882 ; mine in a paper read to the Linnean Society of London on March 16, and issued 

 in their journal on June 12. When Mr Friele's came out in that year I do not know. Now, 

 however, one of the two applications of Mr Dall's name had better cease, and, as I have the 

 opportunity, I may be allowed to alter the name of my species. This I have done above, with 

 a reference to the balance there is between the length of the shell above and below the periphery.

Fusus (Neptunea) futile, Watson, Prelim. Report, pt. 14, Joura. Linn. Soc. Lond., vol. xvi. p. 381. 



Station 150. February 2, 1874. Lat. 52° 4' S., long. 71° 22' E. Between Kerguelen 

 and Heard Islands. 150 fathoms. Coarse gravel. Bottom temperature 35 "2° F. 



Shell. — Thin, pale, fusiform, long, very bluntly ribbed and with equal spiral threads ; 

 the whorls are rounded, the suture rather deep and oblique, the mouth club-shaped, the 

 pillar small and somewhat twisted. Sculpture : In the middle of the whorls are low 

 rounded riblets, which extend to neither suture ; they are parted by shallow rounded 

 furrows broader than the ribs ; the surface is scored with strongish hair-like fines of 

 growth. Spirals — there are clear well-rounded threads, about 9 on the penultimate, and 

 fewer on each preceding whorl ; on the last whorl they are not so equal as on the others, 

 being somewhat stronger in the middle of the whorl ; they are parted by squarish shallow 

 furrows. Colour pale greyish white ; but the specimen is bleached. Spire high and 

 conical. Apex small, smooth, rounded and slightly depressed. Whorls 7, of slow increase, 

 rounded, contracted above, slightly so below ; the last is small, rounded on the base, and 

 prolonged into a small and somewhat twisted snout. Suture oblique, impressed, minutely 

 channelled. Mouth club-shaped, being oval above, and produced into a longish canal 

 below. Outer lip much broken. Inner lip : there is a very narrow thin glaze on the 

 body and pillar, of which the point is bent upwards and twisted. H. - 74 in. B. - 3. 

 Penultimate whorl, height 0-15. Mouth, height 0'36, breadth - 17. 



This species has some resemblance to the young of Fusus (Sipho) lachesis, Morch, but has the 

 apex much smaller, is in form more conical, has the suture more oblique, possesses longitudinal ribs, 

 and has the spirals stronger. Compared with Fusus (Sipho) latericcus, Moll., the apex is much 

 smaller, the whorls are of muGh slower increase, are more rounded, and are more contracted above,
