'roMLIN : SUPPOSED NEW LAND SHELLS FROM SOMALILAND. 55 



Striate from the second whorl onwards, the strife on the last whorl 

 becoming less regular, and sometimes obsolescent ; suture slightly 

 impressed ; umbilical area rather narrow, and the perforation ex- 

 tremely small ; columella considerably reflexed over the umbilical 

 area ; aperture long, oval ; labrum very slightly reflexed. 



Alt. 19 mm. ; diam. lo mm. 

 Aperture, alt. 9 mm. ; diam. 6 mm. 



It appears to be rather a variable species in dimensions ; another 

 adult example measures alt. 22 mm. ; diam. 11 mm. 



The spots are most irregularly placed, and sometimes tend to 

 coalesce into small blotches. This species was found alive in some 

 numbers, but very few were adult. It is dedicated to Mr. F. Booth. 



Ennea orestias^ n.sp. 



Shell cylindrical, perforate; whorls 11^, broadest at the sixth and 

 seventh whorls, and thence to the base gradually decreasing in dia- 

 meter ; sculpture consisting of oblique, rather distant, longitudinal 

 striae, with lines of growth often visible between the striae; suture 

 impressed ; umbilicus very small and deep ; labrum and columella 

 widely reflexed ; aperture almost square, with one prominent parietal 

 lamella, and on the columella two rather less strong lamellse, seated 

 deeply within the aperture. 



Alt. 6"5 mm. ; diam. 3 mm. (in the broadest part). 



This shell is not unlike Ennea uvula Desh. from Reunion, but is 

 smaller, narrowed below, not so strongly striated, and has lamellae on 

 the columella. The latter are too far inside the aperture to be visible 

 in the figure.
