152 M'.W SPECIES OF FISHES, GULF OF CALIFORNIA. 



the base, a black spol greater than the diameter of pupil ou the middle 

 of the outer part, and another on the tips of the last rays. Pectorals 

 with two (list met black bars and mottled with black near the base, the 

 narrow outer edge white; axilla pale; ventrals white on anterior half, 

 the terminal half black; anal white, tips of last rays with a black spot ; 

 caudal with three black bands, the first partly on the peduncle, the 

 second about equal to half the eye in width, its posterior edge at mid- 

 dle of tin ; the third on tip of tin, about equal to snout in width. 



This species is related to 8. fernandeziana Steindachner, from which 

 it differs chiefly in being not so deep, in the naked temporals and oper- 

 cles, and in coloration. 



One specimen, 63 mm long, from (iuaytnas. 



14. Gnathypops ecops, sp. nov. (Typo, No. 39641, U. 8. N. M.) 



Head. 3.5 in body to base of caudal ; width of head 5.75, its depth 

 l.ii; dorsal spines and soft rays, 20 ; anal spines and soft rays, 19; 

 scales, :;-1l':. , -4.0. 



Scales small ; none on head. The lateral line extends to about mid- 

 dle of dorsal tin. Mouth large. Maxillary extends beyond the eye a 

 distance equaling 4.1 in head. The snout is 0.5 in head. Teeth in 

 bands, and on the upper jaw the outer series is rather strong. A single 

 tooth on the vomer. The gill membranes are connected. 



The opercles end in long liaps, which extend upwards and backwards, 

 nearly meeting over the back in front of the dorsal fins. 



Eye large ; 2.5 in head. The interorbital space narrow; 1L in the 

 head. 



There is no depression between the dorsal spines and the soft rays; 

 height of dorsal equals that of anal. 



Ventrals inserted in front of the pectorals; the pectorals equal the 

 ventrals in length, being 7 in the body length ; caudal rounded. 



Coloration, in alcohol: Body pale, covered with many dark spots 

 about the size of three to six scales. The top of the head with 

 smaller dark spots; the sides of the head with whitish spots. The 

 dorsal tin with a black ocellated spot equal to the diameter of the eye 

 on the space between the second and fifth spines, the remainder of 

 the fin dark, with many white spots running into each other on some 

 portions, so as to form irregular lines. Base of the anal fin pale; the 

 outer edge black. The caudal fin is dark, with two whitish spots at 

 the base, and a row of six white spots across the middle on alternate 

 rays. Pectorals lighter, with small whitish specks; ventrals dusky; 

 belly pale. 



Three specimens were obtained from the bay at Guaymas, respect- 

 ively 115", 10"", and 7"" in leugth to base of caudal.
