new Fish from Tampico. 228 



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 fenestration, 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, laurce, 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 A\ to 5 in the length of head, inter- 

 orbital width 2\ to 2f. Depth of prasorbital \\ to If the 

 diameter of eye. Jaws equal anteriorly; maxillary not ex- 

 tending to below the eye ; fold of the lower lip not con- 

 tinuous ; 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 ^- 3 , 2^ or 3 between lateral line and scaly sheath 

 at base of anterior part of soft dorsal. Dorsal XV 11, com- 

 mencing above the opercular cleft, the spines increasing in 

 length to the fifth or sixth, thence subequal or slightly in- 

 creasing, the last ^ 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 (tur- 

 quoise 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 prasorbital, the somewhat different dentition, 

 the more numerous gill-rakers, and the longer pectoral fin.
