P. Smithii of Forbes, P. Farrani of Thompson, Fusus 

 elegans of Brown and Leach, and Mangelia Loveneana 

 of Reeve. This last-named author made also a great 

 many other so-called species from the late Mr. Cuming's 

 collection, which will not stand the test of criticism ; 

 but the excellent illustrations that form the chief merit 

 of his c Conchologia Iconica 3 amply compensate for such 

 failures. Mangelia striolata of E/isso is apparently P. 

 attenuata. 



P. accincta (Murex accinctus, Mont.), one of Las- 

 key's pseudo-discoveries, is West-Indian.
