[On limestone at an altitude of over 1000 feet on the top of the 

 ridge overlooking GoUonsir village, and on the S.W. of it (Gollonsir 

 is at the west end of the island) ; not abundant in this locality. — 

 JB. 5.] 



In the form of its aperture this shell approaches the subgenus 

 Bacillum of Theobald, from Eastern India. 



20. Stenogyra fumificata, n. sp. (Plate LXIX. figs. 2, 2 a.) 



Shell dextral, elongately turreted, solid, not rimate ; sculpture 

 irregular-sized fine transverse lines of growth crossed by spiral lines, 

 giving a cloth-like appearance ; colour ruddy ochre ; spire elongate, 

 sides convex ; apex contracting rather rapidly at the sixth whorl, 

 rounded; suture shallow, but well marked ; whorls 11, regular, flat- 

 sided ; aperture semiovate, angular above, rounded below, nearly

[Common on limestone at east end of island. This shell is used 

 often by the natives for a pipe-bowl. — B. £.] 



This is a remarkable form, also with characters somewhat like 

 those of Bacillum, and may eventually be placed in a subgenus of its 

 own next to Bacillum and Prosopeas. 



21. Stenogyra jessica, n. sp. (Plate LXIX. fig. 3.) 



Shell elongately turreted, dextral, decollate in the three specimens 

 obtained, scarcely rimate ; sculpture very fine longitudinal ribbing ; 

 colour white ; spire long, with sides flatly convex ; suture very shal- 

 low ; whorls 8 -|-; sides very flat ; aperture oval, oblique, angulate 

 above ; peristome thin ; columellar margin weak and but slightly 

 reflected.
