THE BRITISH NATURALIST. 



[June 



This shell is allied to a recently published species from the same 

 country, viz.: E. tJielodonta, Melvill and Ponsonby. The denticles in 

 both are nearly similar, although somewhat different, but our shell is 

 twice as large and possesses 8 whorls. 



II. — Helix Melvilliruia, Ancey. 



Having recently described a new species from Walwich Bay, 

 Ovampoland, under the name of Chapmani, I have just been informed 

 the latter name is pre-occupied by Cox, and I venture to suggest the 

 above one for my shell. This belongs to the section Sciilptaria, 

 Pfeiffer, which is quite peculiar to this portion of the African continent 

 including the territories south of Benguella and north of the Cape 

 Colony. 



III. — Neiiia Orbignyi, Ancey.
