202 MR. E. A. SMITH ON MOLLUSCA FROM JAPAN. [Feb. 18, 



rather strongly angulated at the middle ; beneath with convex out- 

 lines, but sloping or contracted inwards, thus being narrower at the 

 base than at the angle, stoutly jalicate and coarsely spirally ridged ; 

 plicae or costse about nine on a whorl, equal in width to the inter- 

 stices between them, becomina; thinner or more or less obsolete in 

 the concavity, on the last whorl attenuated below and produced to 

 the extremity ; transverse lirae stout, four or five beneath the angu- 

 lation, prominent on the ribs, and the same number above the cari- 

 nation, rather finer than the preceding, about twenty in number on 

 the body-whorl ; the interstices between are deep, about as broad as 

 the ridges, all of which are finely and somewhat closely inibricately 

 scaled. Aperture half the length of the shell, white within, exhi- 

 biting about six tubercles near the labrum ; columella smooth, 

 covered with a thin white callosity, only a trifle oblique, tortuous 

 below the middle ; canal short, reflexed. 



Length 20 millims., diam. 10. 



Operculum with a lateral subterminal nucleus exteriorly. 



Bab. Station 27. 



This species is a close relation of TropJion paiva, Crosse, and 

 Trophon hanleyi, Angas, which two species, judging from the shells 

 alone, might conveniently be placed in Stimpson's genus Urosalpinx ; 

 but the operculum of both is fusoid, although not quite typical, and 

 the odontophores have not been examined ; therefore I prefer locating 

 them provisionally in the genus Fusus. Murex calcareus, Dunker 

 (Moll. Jap. p. 5, pi. 1. f. 2), also approaches this species very 

 closely.

I have no doubt of the identity of Lischke's shell with this species, 

 for specimens of it in the Cumingian collection, probably received 

 by Cuming from A. Adams, answer exactly the description in the 

 ' Japan. Meeres-Conchylien.'

Shell fusiform, brownish, much streaked with very dark brown or 

 black, especially between the plications, with white transverse lirte 

 upon them ; rostrum of the last whorl purphsh black. Whorls 9, 

 obliquely tabulated and a little concave above, then acutely angu-
