line. Spinous dorsal of 18 spines. This genus seems to differ from Ldb- 

 risomus in the large scales, differently formed head, and in the absence of 

 nuchal filaments. (Golio, the gudgeon; Clinus.) 



2708. GOBIOCLINUS GOBIO (Cuvier & Valenciennes). 



Head 3 in total length; depth 4$. D. XVIII, 19; A. II, 17; C. 15; P. 

 14; V. 2; scales 30-10. Head nearly as broad as long, its height a third 

 less. Eye large, 2 in head, twice interorbital space ; a very small tentacle 

 over the eye, another on the nostril. Profile rounded between the eyes, 

 descending vertically to the snout, which is very short. Cheeks inflated; 

 the skull a little rough. Mouth reaching to opposite middle of eye, some- 

 what black; teeth small, conic, and pointed; upper jaw with 26 equal 

 teetli, the lower with 16, the last 2 larger and more curved; teeth on 

 vomer and palatines, simple, in 2 irregular rows; gill membranes united, 

 free from isthmus. Body posteriorly compressed. Dorsal slightly notched 

 between spines and soft rays of anal; pectorals equal to ventrals, 5 in 

 total length ; caudal obtuse, 6 in total length. Lateral line disappearing 

 opposite tip of ventral. Color greenish, with traces of cloudy brownish; 

 the cross bands a deep brown, pointed at base of caudal. Lesser Antilles. 

 Known from several specimens, one 2 inches in length. (Cuvier & Valen- 

 ciennes.) Not seen by us ; apparently a strongly marked species. (Gobio, 

 the gudgeon, from its resemblance to Coitus gobio, the miller's thumb.)

876* STARKSIA, Jordan & Evermann. 

 Starksia, JORDAN & EVERMANN, Proc. Cal. Ac. Sci. 1896, 231 (cremnobates). 



This geius is related to Lalrisomus, differing in the large scales, the 

 presence of palatine teeth, the short soft dorsal fin, and the absence of 

 the comb of nuchal filaments. (Named for Mr. Edwin Chapin Starks, in 

 recognition of his work on the fishes of Western America.) 



2709. STARKSIA CREMNOBATES (Gilbert). 



Head 3i in length; depth 4|. D. XXI or XXII, 8; A. II, 19; scales 37. 

 In appearance resembling very strongly the species of the genus Auchen- 

 opterus. Body slender, snout sharp, the jaws equal; mouth wide, oblique, 

 the maxillary reaching vertical from posterior margin of orbit, 2 in head. 

 Teeth small, villiform, forming a band in front of upper jaw, the outer 

 series enlarged; in lower jaw a single series laterally, becoming double 

 in front; similar teeth on vomer and palatines. Eye longer than snout, 

 4 in head; iuterorbital width less than diameter of pupil; opercle ter- 

 minating in an evenly convex process behind, without spinous points; 

 gill membranes broadly united, free from isthmus; no hook on inner edge 

 of shoulder girdle; nostrils with a flap; a single slender filament above 

 eye and 1 or more on each side of the nape. A slight notch between first
