turreted, not angulate at the upper part ; 18 flexuous longitudinal ribs on the 

 last whorl, perfectly smooth except near the suture, where they are divided by 

 a groove, interstices transversely regularly grooved ; canal short, not recurved, 

 columella and interior of the aperture dark brown. 



Long. 14, diam. 4f mil. 



Dredged by Mr. Wood-Mason at the Andamans. 



This shell in many respects resembles Reeve's M. armillata ; the above 

 characters will, however, easily distinguish it. 



Mitea (Tuebicula) eadius ?, Ev. (an djedala, var. ?) PI. VIII. Figs. 



17—18. 



Shell pyramidically fusiform, pointed, shining ; white, with a broad brown 

 band over tbe lower half of the last whorl and witbin the aperture, apex 

 brown ; whorls 10, turreted, more cylindrical and produced than those of 

 31. clcedala, Ev. (fig. 281) or glandiformis, Ev. (fig. 310) ; longitudinally 

 flexuously ribbed, ribs slightly thickened near the suture, interstices regu- 

 larly engraved with transverse striae ; four folds on the columella, the lower 

 one almost obsolete (Eeeve gives only two folds to his M. radius). 



Long. 13J, diam. 4| mil. 



Dredged by Mr. Wood-Mason at the Andamans ; rare. 



This seems to be doubtfully distinct from M. dcedala and glandiformis, 

 both of which are common shells at the Andamans and at Ceylon.; they all 

 appear to run into one another and may prove to be varieties of one and the 

 same species. 



Mitea (Scabbicola) peetiosa, Ev. 



P. Z. S. 1846. 

 Mitra Antonice, H. Ad., P. Z. S. 1870, {Red Sea). 



This species also was lately obtained rather abundantly by Mr. W. T. 

 Blanford in the Gulf of Oman on the coast of Persia, as also was Turricula 

 (Thala) casta, H. Ad. (P. Z. S. 1872, p. 9, from the Eecl Sea) and a new 

 species very closely allied to the latter. 



Eissoina (?) abnoemis, n. sp., PI. VIII, Fig. 23. 

 Shell small, thick, shortly fusiform, white, suture distinct ; apex re- 

 markably abruptly and truncately sinistral, as in the Pyramidellidce ; 

 whorls 6, the two first embryonal, without sculpture, the others longitudi- 

 nally somewhat thickly ribbed (the figured specimen being rather younc, 

 the ribs are less developed than in mature specimens), the last whorl 

 rounded, with about 15 ribs, obsolete towards the base ; throughout trans- 

 versely, closely, somewhat rugosely striated, so as to form minute, indistinct 

 granules where the strias intersect the ribs; columella strongly twisted at base, 

 covered with a moderately widely spread callosity ; aperture small, peculiarly
