7 Red Sea : ex c. Dr. H. Dohrii. 



5 Roweiah and Aden; coll. J. B. Baxter and G. Nevill, Esqrs. 



An intermediate form, as to sculpture, between the two 

 figures in Descr. de I'Egypte. 



9. Risella [Peasiella] roepstorfl3.ana, n. sp. / 



20 Arakan ; ex c. Dr. F. Stoliczka. 



Uniform yellow coloration throngliout ; very small umbili- 

 cus ; nearly smooth above, never subimbricate at the sutures, 

 only very rarely slightly undulately " waved " at the periphery.

 5 Hongkong; coll. R. Hungerford, Esq. 



" Lives on rocks, about high-water mark ! " The narrow 

 umbilicus resembles that of Red Sea specimens. Two of 

 them possess a basal dark zone, as in B. templiana var. nujro- 

 fasciata. Not subimbricate. 



10. Eisella [Peasiella] templianaj «. sp. / 



Exceedingly variable in coloration and sculpture ; seems, 

 however, to be constantly distinguished from the preceding 

 forms by its considerably more open umbilicus, constantly stained 

 of a rich chesnut ; the columella seems to be more distinctly 

 thickened and is of the same colour ; the form I take for my type 

 is evenly, spirally striate above, striation more or less obsolete 

 on the apical two or three whorls ; aperture of a uniform saffron 

 yellow vsdthin ; no subimbrication, or peculiar sculpture of any 

 sort, at the suture ; three or four deeply excavated spiral sulca- 

 tions at base. Long. 8|, diam. 4 mil. 



12 Andamans [type] ; coll. Capt. R. C. Temple, 

 var. nigrofaselata. 



The interior of the aperture shows two dark-brown bands, 

 one quite close to the suture, the other quite at its base ; a 

 rather broad, dark-colou^red band also round the base, just below
