Jordan and Evertnann. — Fishes of North America. 883 



" This fish, the ' Coelho ' or Rabbit Fish of Madeira, lives habitually at 

 the bottom, and is taken at most seasons at a depth of from 100 to 300 

 or 400 fathoms, and in the summer months, according to Lowe, it is gen- 

 erally one of the commonest and cheapest fishes in the market, where it 

 is sold in bundles, chiefly to the Portuguese. It breeds in August and 

 September, and attains a length of 1^ to 2^^ feet. It is a very wary fish, 

 its name of rabbit fish being due to its habit of snapping off bait. Sev- 

 eral specimens were obtained in Bermuda in 1877 by Dr. Goode. The 

 fishermen obtain it at a depth of 60 to 100 fathoms, and it is known to 

 them as the ' Catfish.'" (Goode & Bean.) (Prometheus, a classical name 

 "par line allusion facile d saisir.")

We provisionally associate with rromefhichthys, the fish called Dicrottis 

 parviinnnis by Goode & Bean, the very young or larva of some unknown 

 species. If the small number of dorsal and anal rays is permanent, this 

 species would form a new genus, between Prometliiclitliys and Gempylus, 

 the small soft dorsal and anal marking a transition toward the Lepidopidw.
