Station 75. July 2, 1873. Lat. 38' 38' N., long. 28° 28' 30" W. Fayal, Azores. 

 450 to 500 fathoms. Volcanic mud. 



Habitat. — Mediterranean , 92 to 1465 fathoms ; Bay of Biscay, 227 to 994 fathoms ; 

 North Atlantic, 227 to 1456 fathoms (Jeffreys). 



Fossil. — From the Middle Pliocene of Calabria (Seguenza). 



I have not seen Professor Verrill's Actceon nitidus (Cat. N. Eng. Mar. Moll., p. 540, pi. lviii. 

 fig. 21), hut, judging hy his figure, and knowing how admirable these figures generally are, I strongly 

 suspect that his species is the same as this of Dr Jeffreys.
