"M. cariiiinatus Goocle. 

 Silver -gray. Body stouter than in M. bairdi, the tail less attenuate. 

 Scales heavy, covered with long spines arranged in nine or ten rows, 

 like wool-cards (carmen), those of the middle row similar to the others. 

 Eye as deep as width of interorbital space, 5 in head. Snout long, 

 sharp, depressed, triangular, 3 in head, its lateral ridges well devel- 

 oped, running in a straight line under the eyes; a strong horizontal 

 ridge from supraorbital to gill-openings parallel with subocular ridges; 

 barbel very short. Long ray of dorsal unarmed; anal rather high, its 

 longest rays equal to half width of interorbital space; pectoral not 

 reaching anal ; ventral behind pectoral, its filament not reaching anal. 

 Head 5; depth 8. D. 10-80+ ; A. 76 + ; P. 13; V. 7; scales ca. 5-100- 

 12. Gulf Stream, off the coast of Rhode Island. (Goode.) 

 (Goode, Proc. IT. S. Nat. Mus. 1880, 346.) 



aa. Suborbital region without conspicuous bony ridge. 



1253. I?I. bairdi Goode & Bean. 



Brownish gray, bluish below; membrane of first dorsal and under 

 surface of snout pink; throat and branchiostegals deep violet: front 

 of dorsal and anal blackish. Snout sharp, quadrate, shorter than eye, 

 with 4 radiating ridges; bony ridge of preorbital and suborbital obso- 

 lete, this region unarmed and soft to the touch; mouth less distinctly 

 inferior than in other species. Scales keeled; first long ray of first 

 dorsal strongly serrate anteriorly; vent under middle of first dorsal. 

 Head G; depth 8. D. 12-137; A. 120; scales 6-1 52-20. Beep water, 

 oft' the coast of New England. This species approaches CoryphcenoideS) 

 and renders the distinction of the genus Macritnis doubtful.

 ((miner, Trondhj. Selsk. Skrift. iii, 50, 17f>.~>: type Coryphtenotdes r>ip<'x1rin Gunner. ) 



Snout short, obtuse, high, obliquely truncated, soft to the touch, 

 exeept its bony center; cleft of the mouth lateral; head without prom- 

 inent ridges, the membrane bones of the side of the head sol't and 

 papery; teeth in the outer series of upper jaw s ...... -what enlarged. 



Scales smooth or spinoiis. Lower jaw with a barbel. (/.<>/>uui-;a, Cory-
