35. Cremnoconchtis faietjanki. 



" Cremnoconchus fairbanlci, Blanford," Hanley, Conch. Ind. p. 58, pi. cxlvi, fig. 7. 

 I have described the species here attributed to me, and I greatly 

 doubt my being responsible for the specific name, even in manuscript. I 

 . find amongst my collection a small box of G. carinatus, labelled G. fair- 

 hanlci, but I cannot recollect whence the name was derived. The shell 

 figured in the ' Concliologia Indica' resembles (7. carinatus in form, but 

 the angulation of the last whorl is not shewn, and the-- coloured bands 

 represented are not, so far as I know, found in that species. 



The shell figured in the same plate of the ' Concliologia Indica' (pi, 

 cxlvi, fig. 10) as O. carinatus, is certainly not that species, but G. conicus, 

 var. Some of the references in the letterpress, p. 58, to my descriptions 

 and figures of Gremnoconchus (J. A. S. B. 1870, xxxix, pt. 2, pp. 10 — 12, 

 pi. 3, figs. 3, 4, 5) are incorrect. 



36. COUBICULA IRATADICA. 

 " Cor. iravadica, Blanf. MSS." Hanley, Concli. Ind. p. 62, pi. civ, fig. 8. 



Testa fere cBqxdlateralis, rliomhoideo ovata, ventricosa, solidimcula, 

 concentrice striata atque costulis siihremotis, interdiim plus inimtsve ohso- 

 Ictis, ornata, epidermide olivaced induta, intus violacea : latere antico ante 

 umhones prominentes suhliorizontali, tunc fere regulariter convexo, postico 

 declivi, oblique subtricncatulo, demum suhangulato, inargine ventrali modice 

 arcuato ; ligamcnto postioe suhito contracto. Lat. 10|- mm., long. 9, crass. 7. 

 In alio exemplo long. \\\, lat. 8^, crass. 7. 



Hab. Ad Mandelay, urbem capitalem regni Avse. 



Shell nearly sequi valve, rhomboidally ovate, ventricose, thickish, con- 

 centrically striated and ornamented with ribs rather wide apart often more 

 or less obsolete. The colour of the epidermis is olive, that of the shell 

 inside violet; Antei'ior side nearly horizontal in front of the prominent um- 

 bones, then almost regularly convex, the posterior side slopes away gently 

 at first, then sharply, almost as if truncated, and forms a rounded angle 

 ■with the ventral margin, which is gently arcuate. The ligament behind is 

 suddenly contracted and compressed, the hindermost portion, about a quarter 

 of the length being very much smaller than the rest. 



Dimensions of one specimen : — length 0'12 inch, breadth from um- 

 boncs to ventral margin 0'36, thickness 28 ; of another much longer 

 shell, the same measurements are 0'46, 0'34, and 0'28 inch. 



It is very possible that this may not be separable from some of the 

 numerous other forms of tlie genus, but I can find none precisely agreeing. 

 The form is more ventricose and the umboncs more prominent than in most
