Color. — Uj)per surface light fawn color, fading at the edges into 

 the dirty white of the belly: a few white spots scattered over the 

 upper surface of the body ; these are much less prominent than de- 

 scribed in B. moresbyi. 



Entire body and fins, except the caudal, enveloped in a loose flabby 

 skin. 



This species is well differentiated from B. moresbyi by the differ- 

 ence in color, greater width of disk, difference in relative size of 

 dorsal fins, and in the greater development of the eyes, which may be 

 due to the less depth of water in which it lives. 



This species is known from a single specimen, a female 33 cm. (13 

 inches) long, from station 2661, steamer Alhatross., of the U. S. 

 Bureau of Fisheries, lat. 29° 41' N., long. 79° 55' W., depth 373 

 fathoms; bottom coral sand. Collected May 4, 1886. 



Type.— Cat. Xo. 62917, U.S.N.M. 



Cervina, like a deer, from the fawn color.
