MARINE BLIND FISHES. 11 



The fishes, blind or partly blind, living in the depth of the ocean bordering the 

 American continents are Ipnops murrayi Giinther and Ipnops agassizii Garman. 

 The former lives at depths varying from 955 to 2,158 fathoms and is very widely 

 distributed. The second one is known from the type specimens from Lat. 2° 34/ N., 

 02° 6' W-, at a depth of 1,360 fathoms. Ipnops stands alone in a family and is the 

 only vertebrate in which no eyes have been found. 



The Brotulidae have several members blind, or with very minute eyes, in various 

 parts of the globe. With the exception of the fresh-water species of Cuba, the 

 only ones found in the neighborhood of America are Aphyonus mollis Goode and 

 Bean, 955 fathoms, and Alexeterion parfaiti Vaillant, 2,736 meters. Other deep-sea 

 blind fishes are Aphyonus gelatinosus Giinther between Australia and New Guinea, 

 1,400 fathoms; Mancalias shufcldtii Goode and Bean, 372 fathoms; Paroneirodes
