XXIII.—Description of a new Fish of the Genus Cichlosoma from Tampico, with JSotes on some other Fishes from Mexico and the Caribbean Sea. By C. Tate Regan, M.A.
During a recent visit of Sir Frederic Johnstone's yacht 'Zena'ida,' R.Y.S., to Mexico and the Caribbean Sea a number of fishes were obtained. Several were caught with rod and line by Laura, Countess of Wilton, who has presented them to the British Museum, and others were collected by Dr. P. R. Lowe. Among them are examples of a little blenny, Enneanectes
carminalis, Jord. & Gilb., a species hitherto known only from Mazatlan, on the Pacific coast. These were captured by Dr. Lowe at Swan Island, between Honduras and Grand Cayman, and, so far as I can judge from comparison with the published descriptions and figures, they do not seem to differ from the Pacific coast form. The freshwater fishes include a large specimen of Cichlosoma fenestratum, Giinth., from the R. Coaxacoalco, without cross-bars and with the lateral band quite black, extending forward to the eye, and on the sides occupying nearly the whole of the space below the lateral line. From Tampico were obtained several examples of Cichlosoma steindachneri, Jord. & Snyd., and two of a new fish for which I propose the name
Cichlosoma laurm, sp. n.
Depth of body If in the length, length of head 3. Snout as long as postorbital part of head, with straight oblique profile. Diameter of eye 4^ to 5 in the length of head, interorbital width 2£ to 2f. Depth of praoibital 1£ to If the diameter of eye. Jaws equal anteriorly; maxillary not extending to below the eye; fold of the lower lip not continuous; upper jaw with about 36 teeth in the outer series, gradually decreasing in size laterally ; lower jaw with the anterior 8 or 10 teeth somewhat abruptly differentiated from the smaller lateral teeth. Cheek with 5 or 6 series of scales. 7 gill-rakers on the lower part of the anterior branchial arch. Scales 28 2£ or 3 between lateral line and scaly sheath at base of anterior part of soft dorsal. Dorsal XV 11, commencing above the opercular cleft, the spines increasing in length to the fifth or sixth, thence subequal or slightly increasing, the last i the length of head; soft fin, when laid back, extending about to the middle of caudal. Anal V 8-9. Pectoral shorter than the head, not extending to above the anal; outer ventral ray more or less produced, nearly or quite reaching the origin of anal. Caudal rounded. Caudal peduncle $ as long as deep. Olive-brown, with blue (turquoise or ultramarine, according to Dr. Lowe's notes) spots on the head and body, one on each scale, the ground-colour in places reduced to a dark reticulation; soft vertical fins with similar spots.
Hab. Tampico.
Two specimens, 190 and 230 mm. in total length.
The nearest ally of this species is C. macracanthum, Giinth., which is distinguished by the coloration, the shorter snout and narrower praeorbital, the somewhat different dentition, the more numerous gill-rakers, and the longer pectoral fin.
