 • Fourth Supplement. 



I have been indebted to the kindness of Dr. Fischer for an 

 opportunity of examining the Mollusca which were procured last 

 summer by the deep-sea exploration in the French Government 

 steamer ' Talisman ' off the west coast of Spain and the coasts of 

 ]\Iarocco, Senegal, Sahara, Cape de Yerd Isles, Canaries, and Azores. 

 This examination will be seen to have greatly enriched the present 

 Supplement. I also wish to recognize the laborious care taken by 

 the Marquis de Folin in his "triage" of the sifted material from 

 the deep dredgings in this Expedition.
