Depth 6%; head to hind edge of gill opening 5%, width I14. 

 Snout 2% in head; eye 13, 514 in snout, 7% in interorbital ; mouth 

 width 214 in head to hind opercle edge; lips and barbels all more 

 or less papillate; nasal barbel reaches pectoral origin, maxillary 

 1% 6ye diameters beyond depressed pectoral fin, outer mental to 

 tip of pectoral spine, inner mental to pectoral origin; teeth fine, 

 conic, in rather broad bands in jaws, also little broader crescentic 

 band on palate ; interorbital 2 in head, broadly and slightly convex ; 

 front fontanel 2^/2 times eye, hind one equals eye; occipital process 

 broadly convex, length about % its basal width. Gill rakers 4+11, 

 lanceolate, % gill filaments which little over twice eye diameter. 



Skin smooth. 



D. about 62, last ray for % basal length joined with caudal, fin 

 height 1% in head to hind opercle edge; A. 63, last ray joined with 

 caudal % its length, fin height 1% in head; caudal 1%, rounded

Dull olivaceous generally, slightly paler on belly and under sur-

British Malaj^a, Siam, East Indies, Philippines? My example ap- 

 pears to differ from most accounts of this species in its spotted colora- 

 tion and partly confluent vertical fins.
