374 THE MOLLUSCA COLLECTED BY THE " HUXLEY " FROM THE 



A rather difficult species, and I can lind only one specimen in the 

 British Museum (Nat. Hist.), and this appears to be similar to the 

 solitary specimen under consideration, which is in rather a bad state. 

 Jeffreys (Moll, of Lightning- For cupine Expds., 1868-70, part v, 

 P. Z. S., 1882, p. 657) decides in favour of its validity. It is a rare 

 shell, which has been recorded only from the Bay of Biscay, Portuguese 

 and Spanish coasts, and in the Adriatic. The Talisman dredged it off 

 Senegal and in the tropical seas, in 1883, from four stations. 



Station IX. 240 fathoms. One dead, corroded shell.
