Shells from South America. 513 



Tliere is a fine series of this species in the British Museum, 

 received in 1854 under the name of ^^Biiceinum hoUvianum,^'' 

 and labelled as coming from Oobija, which place is now well 

 within Chilian territory, though formerly belonging to the 

 Kepublic of Bolivia; as I am unable to trace the name 

 " holivianum " in any work, I have thought it well to describe 

 and figure the species as above.
