SICYDIUM MONTANUM, A NEW SPECIES OF GOBY 



FROM VENEZUELA. 



BY CARL L. HUBBS. 



Dr. Ned Dearborn collected on February 1, 1908, in a moun- 

 tain brook at Macuto, Caracas, Venezuela, eleven specimens 

 of a small goby belonging to the genus Sicydiutn. The species 

 is undescribed, and related to 5. punctatum Perugia and S. 

 buscki Evermann and Clark, but differs from both in its still 

 larger scales, in coloration, and in other characters. 

 Sicydium montanum, new species. 



Holotype. — A specimen 29 mm. long (to caudal), Cat. No. 9053, Field 

 Museum of Natural History; collected by Ned Dearborn in a mountain 

 brook at Macuto, Caracas, Venezuela (February 1, 1908). Paratypes — 

 Ten specimens taken with the holotype, 21 to 28 mm. long. 



Dorsal rays, VI-I, 10; anal, I, 9 (9 or 10). 



Scales comparatively large, about 48 (to 46) in a median series from 

 upper edge of pectoral to end of last vertebra. Each scale deeply sculp- 

 tured over the greater portion of its surface by long basal radii, but bearing 

 a few strong hastate spines in a single series near its posterior margin. 

 Scales obsolescent above pectoral fins and on nape, absent from belly. 



Body slender, scarcely compressed anteriorly; greatest depth, 5.4 (to 

 about 7.0) in body; depth of caudal peduncle, 1.6 in its length from end 

 of anal base, 2.3 (to 2.5) in head. 



Head blunt, and a little depressed, flattened above; its length, 4.25 

 (4.0 to 4.5). Eye placed high, its upper edge entering the profile of the 

 head; its length, about 4^0 in head; interorbital a little narrower than eye. 

 Snout blunt, overhanging the inferior mouth, its length 2.8 in head (shorter 

 in young, in which it is about as long as the eye, and contained about 4.0 

 times in the head. Upper jaw, 2.5 in head, extending horizontally back- 

 ward slightly beyond the vertical from middle of pupil (mouth smaller in 

 young). Premaxillary teeth brownish, set comb-like in a single series
