older to 57/,. Head 37/, to more than 4, much broader than 
high, its crown granulated; occipital process triangular, with 
a median keel, longer than broad at its base, with straight 
borders, its truncated hindborder touching the basal bone of 
the first dorsal. Median fontanel shallow, narrowing posteriorly 
and ending at some distance from the occipital process. 
Humeral process triangular, strong, with waved rugae. Dorsal 
profile nearly straight. Snout obtuse when young, when adult 
pointed and projecting much beyond the lower jaw. Eye 
3—6, with a free orbital margin, about twice in the snout, 
which is nearly equal to the postorbital 
part of the head. Maxillary barbels reaching 
to base of pectoral, mandibulary barbels '/,, 
mental barbel about '/, shorter. Height of 
dorsal somewhat less than head, osseous 
part of its spine granulated in front, serrated 
behind, about equal to head without snout. 
Base of adipose fin much shorter than its 
height, equal to half length of dorsal, 6—7 Fig. 114. Arius tha-

that of dorsal. Ventrals reaching on anal, their length equal 
to height of dorsal, slightly shorter than pectorals, the spine 
of which is flattened granulated in front, serrated behind,

arcuated broad band, in the lower jaw in a divided, somewhat 
narrower but more curved band. Teeth on the palate in two 
large, triangular, separate patches, the base of each triangle 
formed by two more or less quadrangular patches, the outher 
of which is the larger; behind them a much larger subtrian- 
gular patch. g rather stiff, cylindrical gillrakers, the longest
