NEW FISHES 215 



Body short, low, with dorsal and ventral profiles subequal, moder- 

 ately compressed ; head with rounded dorsal profile, somewhat com- 

 pressed, width equal to depth of the caudal peduncle ; mouth small, 

 oblique ; tip of snout formed by the projecting mandible ; maxillary 

 short, extending to vertical from anterior border of pupil ; both jaws 

 armed with a double series of teeth, the inner series small, the outer 

 enlarged and spaced, consisting of four canines in each jaw. 



The scales finely ctenoid, large, thirty-eight in a line from base of 

 pectoral fin to last vertebra. Head naked ; body scaled excepting nape, 

 breast, and belly mesially, which are naked. Dorsal fin deeply notched 

 before the seventh spine, spinous part greatly produced, second spine 

 longest and reaching twelfth dorsal ray, third slightly shorter, first 

 spine exceeding fourth in length ; all the spines flexible and united 

 by membrane to their tips. Soft dorsal lower, little rounded ante- 

 riorly, ending squarely behind, posterior rays equaling the median in 

 height and reaching base of caudal fin ; anal fin similar to the soft 

 dorsal in shape and equaling it in height ; caudal rounded or subtrun- 

 cate, equaling head in length. Pectorals pointed, upper rays atro- 

 phied, lower free at tips ; median rays longest, reaching anal fin ; 

 ventrals free from belly, pointed, reaching vent. 



Coloration in Alcohol. Dark brownish, head and belly lighter 

 brownish-yellow, body crossed by nine narrow, light, black bordered, 

 vertical stripes ; a vertical bar below eye, another on opercle, a curved 

 interorbital, a short occipital and a nuchal bar, and two postocular 

 spots light, bluish-black bordered like the vertical body stripes ; caudal 

 fin dusky with a few light spots at base, the other fins lighter ; dorsal 

 spines blackish. 



Another specimen secured at Tagus Cove, Albemarie Island, is 

 somewhat larger and lighter colored than the type, with the dorsal 

 spines less produced, the longest reaching only to the fifth vertical 

 stripe. The coloration in life of this specimen was as follows : Body 

 pale-lavender, crossed by ten narrow, vertical, light-blue, black-mar- 

 gined stripes, these stripes obsolete on the belly ; the head below the eye 

 and the snout golden, above and on nape bright red, interorbital region 

 olive ; bars and spots on the head distributed as in the type and colored 

 like the vertical body stripes ; fins dusky, reddish tipped ; iris light olive. 



This species is apparently nearest G. dalli, of the Santa Barbara 

 Islands, which it resembles in shape and in the character of its teeth 

 and fins ; but the dorsal spines are much more produced, the scales 

 larger and the coloration very different in pattern. 



Named for Dr. Charles Henry Gilbert, of Stanford University.
