straight line to the broad snout, which is slightly prominent 

 and equal to about '/ 3 the length of the head and about twice 

 as long as the eye. Interorbital space flattened, 2 3 times the 

 diameter of the eye. Upper surface of head granulate, occipital 

 process triangular, very narrow, separated or nearly separated 

 by a cutaneous interspace from the long, prominent basal bone 

 of the dorsal spine. Median groove very short, extending about 

 to the vertical through the hindborder of the eye. Nasal barbels 

 reaching to hindborder of eye or somewhat farther, maxillary 

 ones to the anal, mandibulary ones halfway on pectorals, mental 

 ones about half their length shorter. Height of dorsal equal to 

 head without snout, its flattened spine serrated behind, equal 

 to postorbital part of head. Base of adipose fin rather shorter 

 than that of the dorsal, its length being less than one half of 

 the distance between both fins. Anal rounded, its highest rays 

 longer than postorbital part of head. Ventrals broadly rounded, 

 inserted behind dorsal, reaching to anal. Pectorals equal to head 

 without snout. The strong and flattened pectoral spine is as long 

 as head without snout, about ! / 4 longer than dorsal spine, its 

 hindborder strongly denticulated. Caudal deeply forked, the lower 

 lobes shorter and rounded. A crescentic vomero-palatine band 

 of villiform teeth, equal to that on the jaws. Greyish brown, 

 undersides of head and body whitish. Nasal and maxillary bar- 

 bels and distal part of fins blackish. Length 450 mm.

(BLEEKER, Ichth. Arch. Ind. Prodr. I. Siluri, 1858, p. 130). 



Rather elongate, much compressed; nape and base of dorsal 

 much elevated. Head conical ; snout blunt, prominent before 

 the transverse, rather small mouthopening, with thick lips. Skin 

 covers the eyes and conceales more or less the occipital process, 

 which touches the prolonged, somewhat carinate basal bone 

 of dorsal spine. Anterior nostrils tubular, in the frontpart of 

 the snout. Posterior nostrils valvulate, near eye. 8 barbels, the
