length, llead larg'e, 3^ in length, in a specimen 1 foot long. iSnout 

 projecting beyond profile, bluntly ronnded, the lower jaw included. 



Mouth large, the maxillary reaching nearly to vertical from posterior 

 border of lower eye, 21 in head. A blunt projecting process anteriorly 

 from head of maxillary. Teeth small, pointed, in a single close-set 

 series in each jaw, none of them enlarged. Vomer toothless. Lower 

 eye slightly in advance of upper; vertical from front of ui)per, falling 

 midway between front of orbit and front of pupil of lower eye. Verti- 

 cal diameter of upper orbit but little more than one-half its longitudi- 

 nal diameter, which is contained 3i in head. Interorbital space a blunt 

 high ridge, entirely scaleless, its width two-fifths diameter of orbit. 

 Anterior nostril of blind side with a very long flap, that of eyed side 

 shorter. A well-marked cutaneous flap on lower eye above pupil. 



Gill rakers very large, broad, and strong, well toothed on inner edges ; 

 the longest equals diameter of i)upil ; number on outer gill arch ten or 

 eleven. 



First dorsal ray over anterior margin of upper pupil, the tin not 

 high, its highest ray 3 in head. Anal similar. Caudal shari)ly double 

 truncate, the median rays i)roduced. Ventrals rounded, equal, barely 

 reaching front of anal. No spine before anal fin. Pectorals moderate, 

 with nine or ten developed rays, half length of head. V. G. 



Scales rather small, growing distinctly larger posteriori v, everywhere 

 smooth. Head scaled, except snout, interorbital area, mandible, and 

 part of maxillary ; the latter with a patch of scales on the posterior 

 end of its expanded portion. On blind side an area around nostrils, 

 and the greater part of the exposed portion ot preorbital, scaleless. 

 Fin rays of vertical fins, all with bands of fine scales, those on caudal 

 especially broad. Lateral line with a broad arch in front, the chord 

 of which is 3f in straight portion. 



D. 76 to 83; A. 58 to 62. Lat. 1. (pores) 97. L. 12 inches. 



Color: Duskj^-brownish, with two conspicuous pairs of round black 

 spots narrowly edged with gray, the anterior pair about half size of 

 orbit, the posterior larger than ])upil ; the anterior pair are under be- 

 ginning of posterior third of dors^, and are about half way between 

 lateral line and dorsal find j*BStfnuargins, respectively ; the posterior 

 pair are nearer outlines oWf)ody, and are about under the tenth before 

 the last doisal ray. Vertical fins obscurely blotched with darker. 

 Ventral of eyed side with a conspicuous black blotch margined with 

 white, occupying the distal portioiL^f its inner two lays. Pectoral 

 unmarked. Membrane^^^giU cavity and peritoneum white. 



Two specimens, about 12 inches long, from the Gulf of California, 

 taken in 29 and 76 fathoms. Stations 3014 and 3016. 



90. Cynicoglossus bathybius sp. nov. 



A well marked species differing from its congeners in its much 

 greater depth and bright coloration, and in having the teeth well 

 developed on both sides of jaws, as in the species of Glyptoccphalus.
