straight line to the broad snout, which is slightly prominent 
and equal to about '/, 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 half way 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 '/, 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
