into an upturned and curred hollow hook. Its canal too, like some 

 examples from the Andaman Islands described by me (P. Z. S. 

 1878), is rather elongate, and directed to the left, or in an opposite 

 direction to that of the type. Notwithstanding these differences, 

 and a few other slight ones, I feel convinced that they all belong to 

 one and the same species.

 XX. fig. 31.) 



Trophon fimhriatulum, A. Adams, P. Z. S. 1862, p. 375. 



Shell turgidly subfusiform, turreted, fawn or hght reddish, with 

 a narrow interrupted brown band a little above the middle of the last 

 whorl and almost obsolete above, and dark brown at the apex. 

 Whorls 7, the two apical smooth, the rest sloping at the upper part 

 and rather convex beneath, longitudinally uodosely plicated and 

 spirally ridged ; costse or phcse attenuated at ihe top of the whorls, 

 rounded, about eleven on a whorl ; on the last subnodose at the 

 upper part or shoulder, attenuated and becoming obsolete inferiorly ; 

 spiral lirse about nine in number on the upper volutions, whereof the 

 upper three or four on the slope are finer than those beneath, which 

 appear at intervals to be somewhat imbricately scaled ; last whorl 

 rather suddenly contracted below the middle, with about twenty- 

 eight transverse lirse, the interstices being moderately deep. Aper- 

 ture ovate, pale pinkish or flesh-colour within ; labrum thin and 

 crenulated at the margin, strengthened with a strong imbricated 

 exterior varix, extending downwards almost to the extremity of the 

 Cauda; columella arcuate, pale rose; canal closed, as long as the 

 aperture, curved to the right, slightly retroverted and brown at the 

 tip. 



Length 19 millims., diam. 7g.

Like Murex japonicus of Dunker, this species is remarkable for 

 the absence of varices, with the exception of the postlabral one, in 

 which respect it calls to mind certain species of Tritonium — for 

 example, T. stravyei, A. Adams and Angas ; but in that and other 

 allied species the canal is not closed.

This shell, 1 believe, is the young state of an undescribed species. 

 It is subpyriform, white, purple at the apex, longitudinally plicate, 

 and very beautifully spirally lirate, the liraj being most prettily im- 

 bricately scaled. The aperture, together with the canal, occupies 

 two thirds of the entire length (10 millims.). 



46. Urosalpinx innotabilis. (Plate XX. fig. 32.) 



Shell ovately or shortly fusiform, whitish, with two transverse 

 somewhat interrupted brown hnes on the last whorl, the upper one 

 of which is visible on the upper volutions. Whorls 9 ; two apical 

 smooth, convex ; the rest turreted, concave at the upper part, then
