182 G. & H. Nevill — New Species of Marine Mollusca. [August, 



Glatlmrella enginceforniis. 



Convex, narrowly elongate, resembling certain species of Migina, pecu- 

 liarly attenuated and contracted at base, spire pointed ; white, with a single 

 broad irregular yellow band ; whorls seven, distantly reticulated, the inter- 

 stices under the lens closely longitudinally striated, regular and rounded 

 granules where the ridges bisect one another ; sinus deep, but contracted j 

 aperture very straight and narrow. 



Long. 5-J, diam. 2f mil. Ceylon. 



Glatlmrella contortula. 



Globosely conical, peculiarly bent, apex very obtuse, white ; whorls six, 

 longitudinally prominently ribbed, distantly transversely striated, imparting 

 a granulose appearance to the ribs ; columella peculiarly twisted, aperture 

 narrowly contracted ; allied to Reeve's PI. obtusa. 



Long. 5J, diam. 2f- mil. Ceylon. 



Glatlmrella Blanfordi. 



Elongate, cylindrically ovate, apex sharp and pointed, deep violet- 

 coloured throughout ; whorls 7|-, longitudinally and transversely ribbed, ribs 

 very prominent, of equal thickness, forming granules where they bisect one 

 another ; an excavated furrow near the base of the last whorl ; sinus rather 

 large, columella short and twisted, aperture moderately wide, contorted. 



Long. 5f, diam. 2i mil. Annesley Bay, Red Sea. 



Glatlmrella Armstrongi. 



Pyramidically elongate, angular in the middle of the whorls, very point- 

 ed at base, apex sharp, uniform brown throughout ; whorls 8, obtusely and 

 distantly longitudinally ribbed, transversely striated ; columella peculiarly 

 twisted with a shining callosity which is rugosely granulated as in Gytliara ; 

 aperture short and contorted, sinus remarkably deep. Allied to PI. arctatct 

 of Reeve. 



Long. 5, diam. 2\ mil. Andamans and Paumben Straits. 



Gytliara gradata. 



Narrow, ovately oblong, apex very obtuse, pure white throughout ; 

 whorls six, reticulated ; columella straight, slightly rugose ; aperture con- 

 tracted, sinus small, outer lip very thick, rounded. 



Long. 5f , diam. 2 mil. Ceylon, Bombay. 



Gytliara dubiosa {? coniformis, Gray). 



Very closely allied to, if not the same as, Gray's coniformis; greater 

 thickness, straighter outer lip, and less oblique longitudinal ribs seem to 

 distinguish this form. 



Long. 7f, diam. 4 mil. Mauritius, Andamans.
