194 THE VOYAGE OF BLM.S. CHALLENGER. 



already perplexes this species, I would have classed it as a Fasciolaria. In the circumstances, 

 however, I think it better simply to note that towards the front of the pillar, above the narrowing to 

 the canal, the lip is crossed by 2 or 3 slight nearly horizontal teeth. These teeth are quite distinct 

 from though much obscured by the strong oblique spiral threads of the external sculpture, and 

 coil round the pillar and form ridges and furrows through the thin callus of the lip ; these ridges are 

 peculiarly strong on the body at the top of the mouth within the lip. 



5. Fusus hanleyi (Angas).

April 17 to 18, 1874. Port Jackson, Sydney. 2 to 10 fathoms. 



Habitat. — Port Jackson (Angas). 



The operculum of this species is not that of Murex nor of Fusus, still less that of Urosalpinx, being 

 subspiral like that of Neobuccinum, but the character of the shell, and the great length of the canal 

 in particular, make its union to that genus impossible. The form of shell and operculum alike 

 remove it from Trophon. In perplexity, I have followed the British Museum classification as the 

 best in the circumstances. 



Mr Tryon (Manual, vol. ii. p. 155, pi. xxxix. fig. 499) classes this species as a Urosalpinx, 

 probably in ignorance of the operculum at least, and asserts that it is founded on " elate specimens 

 of Trophon Paivce, Crosse." Mr Angas has had both before him (Proc. Zool. Soc. Lond., 1867, 

 p. 187), and his judgment deserves much respect. He keeps them separate. 



6. Fusus niphonicus, E. A. Smith. 



Fusus niphonicus, E. A. Smith, Moll, from Japan, Proc. ZooL Soc. Lond., 1879, p. 203, pL xx. fig. 34. 



Station 204a. November 2, 1874. Lat. 12° 43' N., long. 122° 9' E. Off Manilla. 

 100 to 115 fathoms. Green mud. 



Habitat— South of Niphon. Lat. 34° 12' N., long. 136° 28' E. 52 fathoms (Smith). 



I incline to class this as a Fasciolaria rather than a Fusus, the better-grown specimen of the 

 Challenger showing indications of teeth on the pillar beyond what can be traced in Captain St 

 John's specimen, from which Mr E. A. Smith described the shell. Still they are very faint, so I 

 leave it under Mr Smith's classification till more and better specimens are found.
