Deep Sea Fisues.—Not less than 3800 specimens of deep-sea 
fishes were dredged in the last voyage of the Talisman. At the 
dredging No. CX., as many as 931 were captured, of which 780 
were EHymenocephalus italicus Giglioli.

Gunther and others, raise the known species of this se ee 
fifteen. Most of these fishes have the dorsal and anal fins ; ro h 
back upon the caudal peduncle, and seem adapted for easy and rap 
locomotion.
