146 NEW SPECIES OF FISHES, GULF OF CALIFORNIA. 



9. Gobius chiquita, sp. uov. (Tj pe, No. 39634, U. S. X. M.) 



Head 3£ in length to base of caudal (t in total); depth, 5 (5§); eye, 

 1 : 8cales37 in Longitudinal, 17 in transverse scries; 1). VI— 9 ; A. 10. 



Body rather stout, compressed; bead short, somewhat depressed, 

 widened behind orbits; snout short and narrowly rounded; profile in 

 front of eye \n\ steep, less so to occiput, and nearly straight from 

 there to caudal tin; eyes moderate, well up, iuterorbital space very 

 narrow, less than eye; greatest width of head equals greatest depth of 

 body. Top of bead, opercles, and space in front of dorsal naked, rest of 

 body covered with small, evidently ctenoid scales, which increase in size 

 upon the caudal peduncle. Dorsal fins two, the anterior of six flexible 

 spines, their length about equal to the depth of the body; the distance 

 from the snout to the origin of the spinous dorsal is a little more than 

 one-third the distauce to base of caudal; the second dorsal of nine, soft 

 rays is but slightly separated from the spinous part, its origin being 

 about midway of the total length of the fish, its rays are not quite so 

 high as are the spines. The anal is of about the same shape and size 

 as the soft dorsal, but begins a little behind it. The pectorals are, 

 tapering, about equal to the head in length, their tips not reaching 

 origin of anal, but to origin of soft dorsal ; ventrals united, free from 

 the belly, inserted behind the pectorals, but their tips not reaching tips 

 of pectorals. 



Teeth apparently, in a single species, small and weak. 



Ground color pale yellowish, thickly mottled with fine punctulations 

 of dark; about seven pretty well-defined larger spots of dark brown 

 along middle of side ; eight or nine faint cross-bars of lighter, a num- 

 ber of small light spots scattered irregularly over the sides ; head dark; 

 dorsal, anal, and ventral tins covered with tine black points, in some 

 specimens the dorsals and anal being quite dark ; pectorals plainer ; 

 caudal similar to the ventrals. 



This species seems most closely related to G.poeyi Steindachner, but 

 differs in that the head is less fiat, the iuterorbital space is less wide, 

 the fewer scales, as well as differing in color. 



Seven specimens were obtained from shallow water in the bay at 

 Guaymas. This species seems to be one of the smallest of the gobies, 

 the largest of our specimens being but 27 mm long. 



10. Gobius longicaudus, Bp.nov. (Type No. 39636, U. S.N.M.) 



(ken-tli of longest specimen, 1.")"".) Head 5 in length to baseof cau- 

 dal (7| in total); depth, 7 (10); eye, 4|j I). Vi-13; A. 13; scales about 

 t'.ti in longitudinal, 15 in transverse series, counted just below space be- 

 tween the two dorsals. Body slender, tapering pretty regularly from 

 middle of first dorsal to caudal, most compressed posteriorly, depth 

 about uniform from head to origin of second dorsal. Head short, de- 

 pressed, and broad. U to 5 in length in twelve specimens measured. 

 io 7', in total length of fish; maxillaries rather short, 3 in head, 

 i '-aching about to middle of eye. wide apart, the distance between them
