third the length to base of caudal. Profile gently arched from snout to 

 half the distance to dorsal fin, from there nearly straight to dorsal, and 

 then gently curved to caudal peduncle ; ventral outline nearly straight; 

 a considerable prominence on the snout made by the enlarged end of 

 the turbiual bone. Eye somewhat above median line, not quite equal- 

 ing the snout in length ; interorbital space narrow, it being contained 

 one and one half times in the eye. The maxillaries are much produced, 

 in some specimens nearly reaching the gill-openings, broadest at the 

 middle and tapering to a blunt point posteriorly ; premaxillaries not 

 protractile, but little movable at the symphysis, more than half as long 

 as the maxillaries. Gill-rakers, two above the angle, ten below, short 

 and blunt, the first four the largest, those on the second arch but little 

 developed. Teeth well developed, in a single series, on mandible and 

 premaxillaries, all slightly curved backwards. 



The tongue is not so broad as in G. mirabilis Cooper; it is gently 

 rounded at the tip, which is free for a much greater length than in G. 

 mirabilis. The peritoneum is black or blackish, and the iutestine short, 

 but little longer than the head, aud not at all convoluted. 



The scales are small, imbedded, and scarcely perceptible except on 

 sides; no pores appear to be developed. First dorsal of fine flexible 

 spines, distance of origin from snout 2j length of body, and separated 

 from the second dorsal by a distance but little greater than length of 

 snout ; second dorsal of fourteen rays of nearly equal length, which 

 equals the distance from end of snout to middle of pupil ; length of base 

 of soft dorsal not quite equal to length of head, distance of posterior 

 end from caudal fin equals distance between the two dorsal fins. Ori- 

 gin of anal behind that of soft dorsal aud a little posterior to middle of 

 total length of fish ; its base is contained one and one-fourth times in 

 base of soft dorsal, or about four times in length offish to base of cau- 

 dal fin. Pectorals moderate, a little more than half length of head. 

 Ventrals inserted slightly behind the pectorals and about equaling 

 them in length. 



Color in life, whitish beneath, grayish or mottled above; six double 

 white spots aloug the back, alternating with fine blackish areas; a 

 white spot behind each eye on top of head, cheeks with two dark bands 

 extending obliquely backward and downward from eye, a number of 

 dark splotches on opercles ; about seven dusky areas along the side, 

 the last and most marked being upon the base of the caudal fin. Dor- 

 sal fins finely marked lengthwise by about four series of small dark 

 spots; caudal crossed by five or six wavy vertical bars of very tine 

 dark spots or points; anal, pectorals, and ventrals plain. In alcohol 

 these markings are less plain, especially the white and black areas upon 

 the back. 



This species is related to G. mirabilis Cooper, from which it may be 

 readily distinguished by the fewer dorsal, spines, the greater number 

 of anal rays, the more slender body, narrower head, and difference in 

 color.
