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



85. MiTRA (Pusia) inermis, Reeve. (Plate XX. figs. 53, 53a.) 



Mitra {Pusia) inermis, Eeeve, Con. Icon. ii. sp. 2/9 ; Sowerby's 

 Thes. Conch, fig. GOO (vile!). 



Hab. Station 5. Island of Luzon {Cuming). 



A single specimen (fig. 53ff), which I consider a variety of this 

 species, differs from the type (fig. 53) in being nearly black, with the 

 white zone less well defined, but marked in the same manner with 

 short black and brown lines upon the ribs. Reeve does not mention 

 the sculpture between the costse : it consists of well impressed lines 

 or sulci, six in number on the upper whorls and eleven or twelve on 

 the last, besides some strong oblique grooves at the extreme base ; 

 the lira; between the latter, of which one is especially prominent, are 

 spotted with white. The figure in the Con. Icon, represents the 

 spire much too turreted and the whorls too flat. The copy of 

 Reeve's figure in Sowerby's Thesaurus is simply as bad as possible. 



86. Cancellaria japonica. (Plate XX. fig. 54.) 



Shell ovate, pyramidal, white, thickish : whorls 7, convex, divided 

 by a deep suture, longitudinally ribbed and spirally lirate ; costse 

 rounded, oblicpie, about 13 on a whorl, rather broader than the 

 interstices ; transverse lira? prominent, six or seven on the penulti- 

 mate whorl and twelve on the last : aperture small, occupying about 

 three eighths of the entire length ; columella with two small central 

 oblique plaits. 



Length 12 millims., diam. 5. 



Ilab. Station 1. 



This species is remarkable on account of its elongated form and 

 the absence of colour. The only sj)ecimen is not in very good con- 

 dition, and the lirse, which are usually met with in the aperture of 

 species of Cancellaria, are not present, and possibly have been broken 

 away with the front part of the labrum, which is incomj)lete. 



87. Oliva (Olivella) consobrina, Lischke. 



Oliva {Olivella) consobrina, Lischke, Japon. Aleer. -Conch, ii. p.

 f. 422, 423. 



? O.fulyurata, Ad. and Rve. Vcy. Samarang, p. 31, pi. 10. f. 12. 



Hab. Stations 7 and 22. Nagasaki {Lischke). 



These three species are very closely related ; and it is somewhat 



doubtful if they are really distinct. If they prove to be so, the name 



fuhjurata will take precedence of the other two by many years. This 



spt'cies was quoted by me in the 'Annals and Magazine of Natural 



History' under the name of O.fulgurata. 



88. Oliva (Olivella) sfreta, Gould. (Plate XX. fig. 55.) 



Olivella spreta, Gould, Otia, p. 127. 



Shell small, elongate-ovate, jiale livid luteous, v>ith light brown 

 indistinct zigzag undulating longitudinal lines : whorls 4|-5, the
