pools, closely allied to tlie Old World genus, Trijytcrygiov, Risso, but dis- 

 tiugnisbed by the chubby body, short fius, and large, rough scales.

2687. ENNEAIVECTES CAKMIXALIS (Jordan & Gilbert) . 



Head 3t; depth 4| to 5i. D. III-XII, 9 (IV-X, 8 in the specimen before 

 us); A. II, 11 (misprinted II, 17) scales 33 to 40. Body rather stout, 

 heavy forward, rapidly tapering behind. Head short, the snout low and 

 rather pointed, the profile straight and steep from the snout to opposite 

 the front of the eyes, there forming an angle and extending backward 

 nearly in a straight line ; eyes very large, longer than snout, 3 in head, 

 hi'>-h up, and close together; mouth wide, the jaws subequal, the maxil- 

 lary extending backward to front of pupil; teeth moderate, essentially 

 as in species of Labrisomits, those of the outer series enlarged; no evi- 

 dent cirri on the head ; scales on body of moderate size, ctenoid, the edges 

 strongly pectinate ; belly naked; lateral line extending to opposite last 

 ray of soft dorsal, ascending anteriorly, but without convex curve; dor- 

 sals 3, the first and second contiguous, the second and third well sepa- 

 rated ; first dorsal of 3 spines, the first of which is the highest and about 

 as long as diameter of eye; the second dorsal of higher and slenderer 

 spines, the anterior the highest, the longest about equaling greatest depth 

 of body ; soft dorsal shorter and a little lower than second spinous dorsal ; 

 caudal small ; anal long, beginning nearly under middle of spinous dorsal ; 

 pectoral long, longer than head, reaching much past front of anal; ven- 

 trals i length of head. Color light brownish, with 4 dark- brown cross 

 bars on sides, about as wide as the inters])ace8, which are marked with 

 more or less reddish and with some lighter spots ; belly pale ; space behind 

 pectoral dark ; a dark bar downward and 1 forward from eye ; first dorsal 

 mottled with darker, second and third dorsals nearly plain; a narrow, 

 dark bar at base of caudal and a broader one toward the tip, the fin some- 

 times entirely black; pectorals somewhat barred; lower fins plain. Ma- 

 zatlan, in tide pools; the types, 4 siiecimens, each about 11 inches long. 

 Another from the same locality, since figured by Dr. Jordan, differs some- 

 what in the count of the fin rays; but the very small size of the specimen 

 prevents us from being entirely sure of its correctness, (carmen, a hetchel, 

 from the rough scales.)

Body rather elongate, compressed, covered with very small, smooth 

 scales, those along lateral line not enlarged; head long and low, the suout 

 conic, produced, very acute; premaxillaries protractile; mouth moderate, 

 terminal; each jaw with a row of conical teeth, behind which anteriorly 

 is a broad patch of villiform teeth; vomer and palatines with villiform, 

 teeth ; gill rakers feeble ; gill membranes broadly united, free from the
