On Deep-sea Mollusca from the Bay of Biscay. 315 



XXXVIII. — The Deep-sea Mollusca of the Bay of Biscay. 

 By J. Gwyn Jeffreys, LL.D., F.R.S. 



During the French deep-sea exploration last July, in the 

 Bay of Biscay, in which expedition I was privileged to take 

 part, on the obliging invitation of the Minister of Public In- 

 struction, I was intrusted with the Mollusca. Perhaps the 

 accompanying catalogue raisonne may interest conchologists.

 1 Travailleur 1 in the Bay of Biscay, 1880.
