Diagnosis. Head three and one third in length; depth four and 

 one sixth ; dorsal profile of head evenly rounded ; snout less than eye ; 

 D. VI I, ii ; A. I, 9. Color, above dark reddish-brown, head and 

 body crossed by fifteen light vertical bars ; head below the level of 

 eye black-spotted ; caudal and dorsal fins finely dark-barred. 



Description of the Type. Head three and one fifth in length ; 

 depth four and one sixth ; eye three and one half in head ; maxillary 

 three ; snout three and seven eighths ; interorbital ten and one third ; 

 D. VI-I, ii ; A. I, 9; caudal 27; pectoral 18. 



Body short, dorsal and ventral profiles low and subequal. Head 

 slightly compressed, width less than height, dorsal profile slightly 

 rounded from snout to nape. Snout short, less than diameter of eye 

 in length. Mouth oblique, with projecting lower jaw ; maxillary one 

 third length of head, extending to slightly beyond vertical from an- 

 terior border of eye. Teeth in a double series in both jaws ; inner 

 small and villiform ; the outer enlarged, canine and spaced. Eyes 

 diameter large, greater than snout, situated close together, the inter- 

 orbital consisting of a thin ridge. 



Scales large, ctenoid, twenty-eight in a line from base of pectoral 

 to caudal fin. Whole head, breast, nape, base of spinous dorsal and 

 fin membranes naked. 



Dorsal fin long, deeply notched before last dorsal spine. Spinous 

 dorsal high, second and third spines somewhat produced but consid- 

 erably shorter than in G. zebra, about one half head in height. Soft 

 dorsal lower, with rays of about equal height, a few of the posterior 

 shorter, not reaching base of caudal fin. Anal fin similar to soft dorsal, 

 but not extending so far posteriorly, height equal to soft dorsal, pos- 

 terior rays nearly as long as others, pectorals in the type with the tip of 

 the rays worn ; normally pointed, one and one ninth the length of head. 

 Ventrals jointed, inner rays longest, as long as pectorals; reaching 

 anus. Caudal rounded, one and one fourth in length of head. 



Coloration in Alcohol. Above, head and body dark purplish- 

 brown ; body crossed by thirteen narrow, light, vertical stripes, about 

 one fourth as wide as the dark interspaces, becoming obsolete on 

 sides anteriorly, the light stripes with a fine dark line running through 

 them ; head crossed by two oblique light stripes behind the eye which 

 cross over the nape ; a pair below eye and a single posterior inter- 

 orbital stripe above eye ; light spaces on head wider than on body, 

 distinct, not forming reticulations ; head below level of eyes and belly 

 lighter, pinkish; the dark areas below eye, the chin and branchio- 

 stegal membranes spotted with dark brown ; soft dorsal and caudal fins
