206 THE MOLLTJSCA OP TOREES STRAITS. 



new subgeneric division. It only remains to say tliat several 

 examples (mostly, however, single valves, thougli one at least 

 occurred quite perfect) were found of -P. Saddoni, dredged at 

 about 5 to 6 fathoms in the localities above cited. It is not, 

 therefore, a deep-sea form. 



In dedicating this mollusc to its discoverer, we would once 

 again tender him our best thanks for having given us every 

 facility and latitude in the preparation of this Eeport ; and, we 

 may add, it is by his express desire that all the types have been 

 permanently deposited in our National Collection at the British 

 Museum (Natural History), South Kensington.
