 Long. b', lot. 1*50 mm. 



Hab. Oharbar, Aiekran Coast, 7-10 fathoms. 

 Of the same character as the European T. rufa Phil., but smaller, 

 and the ribs are continuous beyond the periphery in our species, 

 not evanescent as in rufa. Whorls 11 or 12. the two apical being 

 glassy, vitreous, sinistral, the remainder closely longitudinally 

 ribbed, ribs smooth, interstitially spirally striate. Eight examples 

 were dredged, all precisely similar.

Hab. Linjah, Persian Gulf. 3| fathoms, sand. December 1900. 



Very distinct, though so minute ; being usually entirely rufous, 

 though some examples are almost white, with rufous tinge alone 

 on the body-whorl. It is one of the smallest TurbonilUr yet 

 described, and remarkably graceful in contour. The ribs are nearly 

 straight, acute, crowded, the spaces intervening being seen, with a 

 lens, to be exquisitely closely striatulate ; mouth ovate ; peristome 

 continuous. It bears no close resemblance to any other Eastern 

 species known to us.
