Bulimulus Dukinfieldi, n.sp. 



Hah. — Salto Grande do Bio dos Patos (upper waters of Biver 

 Ivahy), Parana, Brazil (E. D. Jones, Esq.). 



A plain but interesting species, procured from a district hitherto 

 almost unworked, that does not seem much akin to any other of the 

 genus known to me. Two specimens, precisely similar, were obligingly 

 handed me by Mr. B. Dukinfield Darbishire, of Manchester, as 

 collected by his relative, Mr. E. Dukinfield Jones, in 1899. I am 

 much indebted to Mr. S. I. Da Costa for having compared this shell 

 with the complete series of Bulimulus, both in his own extensive 

 collection and that of the British Museum (Natural History), in which 

 latter the type is now placed.
