MOLLUSC A. 475 



very finely costtdate throughout rather than striated. 

 The measurements are identical. 



5. Zonites, sp. 



Meshek. A single specimen only. It is very close to 

 H. egenula, Mor., from Senegal. 



6. Yitrina Ruppelliana, Pfr. 

 Syn. V. Damaudi, Pfr. 



Common in Northern Tigrd about Takonda, Senafe, 

 and Adigrat, above 6,000 feet. V. Darnaudi appears 

 to be only a variety of V. Hiijjpelliana. 1 obtained both, 

 and intermediate forms as well. 



7. V. Ahyssinica, Pfr. 



Takonda. I only found this shell once. My speci- 

 mens are a little more angulate at the periphery than 



the type. 



8. V. sp. nov. 



Ashangi. Found aJive abundantly amongst long grass. 

 The animal is a true Vitrina and not a Helicarlon, 

 haviug no mucus-pore at the end of the tail. 



Two or three specimens found at Lat and Antalo 

 dififer somewhat from this form, but may be varieties 



only. 



9. Suceinea debilis, Mor. 



1 S. Pfeifferi, ex Abyssinia, auct. 

 AshangL There are larger specimens in the British 

 Museum of the same shell, also from Abyssinia, labelled 

 8. Pfeifferi. It differs, however, from all European forms 

 of- that species by its much smaller spire and larger 

 mouth.
