94 ANCEY : SHRLI.S FROM BOLIVIA AND BRAZIL. 



This form, quite a ntw one for Bolivia, is distinguished at 

 a glance from similar species, as O. achatanits Doering, know 

 to inhabit the Argentine Republic. 



Bulimus floccosus Spix ? 

 To this rare and beautiful species I refer, with some doubt, 

 two examples from Santa Cruz de la Sierra, provisionally identi- 

 fied as B. fioccosits. K further examination is necessary, as 

 they may belong to a new species. 



Orthalicus pulchellus Spix. 

 Received from Corumba, Matto-Clrosso (Smith, Germain). 



Nenia orbignyi Anc..^ {''^'' «-~^- 'V"^'J 



This fine novelty, recently published by myself in 'The 

 British Naturalist,' has never been figured. 



It is the second species of the genus described from 

 Bolivia, the other being N. boliviana Bottger, a much smaller 

 form, only 12 mill, in length, belonging to the group of N. 

 adamsiana Pfeiffer, of Chanchamayo, Andes of Peru. 



N. orbignyi is somewhat allied to my N. sfylina, from New 

 Granada, but is larger, less slender, of different colour and 

 shape, and is more finely sculptured, the ribs being z'^rc oblique. 

 ]V. crossei Hidalgo is larger, more elongate, has more numerous 

 volutions, and the colour and sculpture are altogether dissimilar. 



This new species was discovered by Mr. P. Germain, to 

 whom natural history is much indebted for his lesearches in 

 Chili, and more recently in Paraguay, Bolivia, and Matto-Grosso.
