MOLLUSC J. 477 



15. P. sp. nov. 

 Senaf^, Adigrat, Agula, and Meshek. A common form 

 in Tigr^. I can find nothing like it described. The 

 nearest known form is perhaps P. doliolum. 



1 6. P. fontana (?) Kjauss. 

 Same localities as last, and very abundant. It has a 

 vertical groove behind the lip, and an indentation corre- 

 sponding to the lower tooth of the dextral margin, 

 neither of which is described in the South African shell, 

 otherwise it agrees admirably. 



17. P. sp. nov. 

 Agula, and near Takonda, Tigr^. Very near P. urn- 

 bilicata, Drap., but there is one whorl less and the 

 aperture is rounder, not being pointed below. 



18. Vertigo, sp. nov. 



Agula, rare. A small reversed species, of which I found 

 only two specimens. 



19. Claudlia Sennaarensis, Pfr. 

 Near Lat, south of Ashangi. Only an immature 

 specimen, but apparently belonging to this species, 

 was found. 



20. Ennea, sp. nov. 



Meshek, Ashangi, Lat, Wandaj pass. Nowhere com- 

 mon. This is allied to E. crystallum, Mor., but is a 

 much longer and more slender shell, with fewer whorls.
