Head largg, wide, upper profile generally convex, more inclined 

 than lower. Snout short, wide, convex over surface, its length 

 about § its width. Eye large, circular, slightly anterior. Mouth 

 broad, terminal, rather low, and broad fleshy lips similar. Jaws 

 equal. Maxillary extending very slightly beyond front edge of eye. 

 Each jaw with trenchant firm cutting-edge, feebly notched or with 

 slight dentate appearance. Inside mouth skin apparently smooth. 

 Tongue thick, fleshy, front edge free. Upper and lower buccal 

 membranes slight. Nostrils near together, lower in slight tube 

 about opposite middle of eye, and posterior simple pore about 

 opposite upper rim of eye. Interorbital broad and slightly convex. 



Gill-opening high, mostly above upper level of eye, and small 

 aperture about half of eye. Downwards and below, skin forms 

 slight fold. 



Skin almost everywhere, except upper surface of head and front 

 of back, which furnished with a number of bony tubercles, smooth 

 and without any pores. 



Dorsals entirely separated, space between about half of eye. 

 First dorsal much shorter, though higher, than second, and its edge 

 slightly notched. Spinous dorsal inserted over front of gill-opening. 

 Second dorsal and anal similar, rays simple, well defined, and more 

 or less uniform. Caudal moderate, rounded. Pectoral moderate, 

 with long and moderately inclined base, and formed with simple 

 rays. Pectoral reaches far posteriorly as disk. Latter quite large, 

 circular, and not ensheathed in front by pectoral rays, edge entire. 

 Vent close behind disk. 



Color in alcohol largely brownish, contrasted with whitish mark- 

 ings. Color-pattern may best be understood by an examination 

 of the accompanying figure. On head whitish is left radiating as 

 several streaks from eye. First dorsal largely dusky-brown, with a 

 white edge. Vertical fins otherwise pale or whitish. Disk pale. 

 Iris pale slaty.
