Head4; depth 5; orbit 3| in head ; maxillary 2; barbel about 3 in orbit. 

 D. 9 or 10-55 to 57; A. 56; C. 5, 18 to 21, 5; P. 17 or 18; V. 3; scales 

 7-90 or 91-28. Vent situated under the twelfth ray of second dorsal, 

 and equidistant from tip of snout and end of second dorsal; distance of 

 dorsal fin from snout equal to twice length of mandible; third ray of first 

 dorsal extremely elongate, extending to a point (thirty-third ray of sec- 

 ond dorsal) of distance from snout to tip of caudal, its length more than 

 twice that of head, and more than 4 times as long as the rays immediately 

 preceding and following it; anal fin inserted immediately behind vent, its 

 distance from root of ventrals equal to that of dorsal from snout; as in 

 other species of the genus, ventral of 3 rays, the first 2 much prolonged, the 

 first contained 3 times in length of body, the second almost 3 times as long 

 as head, reaching to fortieth anal ray or f of distance from snout to tip of 

 caudal, the third shorter than diameter of orbit; pectoral 4 times as long 

 as operculum. Scales large and thin, easily wrinkling with the folding 

 of the thick, loose skin, particularly in the median line of sides of body. 

 Lateral line much broken on posterior half of body. (Goode & Bean.) 

 Atlantic coast of United States, in 100 to 500 fathoms, with Macrourus 

 bairdi, the most abundant fish on the continental slope, swarming every- 

 where below the 100-fathom line. (Named for Capt. Hubbard C. Chester.)
