** 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. tem^liana var. nigro- 

 fasciata, Not subimbricate. 



10. Eisella [Peasiella] templiana, n. 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 within ; no subimbrication, or peculiar sculpture of any 

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

 tions at base. Long. 3|, diam. 4 mil.

var. nigrofasciata. 



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-coloured band also round the base, just below
