 suturam et apicem costulato- striata, albida, epidermide olivacea 

 minutissime corrugata induta; spira elongato-conica, versus apicem

Long. 20-30, diam. 10-11 mill.; apert. long. 11, lat. 5 mill. 



Var. oxynter testa elongato-turrita, graciliore. 



Long. 30, diam, 8 mill. 



Habitat ad Portum Blair insularum Andamanicarum. 



This species was, I believe, first discovered by Dr. Walker, 

 Superintendent of the Settlement ; but the most perfect speci- 

 mens, with the epidermis in fine condition, were received from 

 his successor, Major Haughton. 



There is a tendency in the stouter form to verge towards the 

 variety which I have called oxynter, although the extreme spe- 

 cimens might be considered as separate species. A single spe- 

 cimen of this variety was sent by Major Haughton. 



7. Spiraxis Walkeri, B., n. sp. 



S. testa imperforata, cylindraceo-turrita, arcuato-striatissima, sub 

 epidermide albida ; spira gracili, apice obtuso, sutura profundius- 

 cula ; anfractibus 9, convexiusculis ; apertura obliqua, elliptica ; 

 margine dextro tenui, acuto, superne arcuato, columellari calloso, 

 subito revoluto.

None of the specimens sent by Major Haughton possess a 

 perfect epidermis, and all are more or less injured at the aper- 

 ture.

S. testa imperforata, elongato-turrita, tenui, arcuato-striatula, albida,

This shell, the first of the genus noted from Ceylon, was col-

 epidermis were very scarce.
