282 MR. C. TATE REGAN ON THE 
twice. Sides of the head, in the male, armed with bristles; snout pointed; supra- 
orbital edges moderately raised ; supraoccipital with a pair of obtuse divergent ridges ; 
orbital notch well developed, triangular ; lips papillose, with short marginal fringes ; 
lower lip rounded ; free portion of barbel nearly equal to the diameter of eye; 6-8 
teeth on each side in both jaws. 25-(?28] scutes in a longitudinal series (in the 
specimen figured 25, 14+-11), all in front of the dorsal distinctly carinate, the lateral 
keels obtuse and united posteriorly. Lower surface of head naked ; abdomen with 5 
series of plates between the lateral series for nearly their whole extent; the anterior 
plates smaller, extending to the level of the middle of the gill-opening; anal plate 
bordered anteriorly by 3, these 5 again by 5. First dorsal ray about # the length of 
head; pectoral spine extending to base of ventral; ventral spine not produced, the 
soft part of the fin rounded, the third branched ray the longest; upper caudal ray 
elongate. Breadth of body at level of first anal ray about 43 times in the distance from 
that point to the caudal. A series of blackish dots on the anterior pores of the lateral 
line; all the fins with dark spots on the rays. 
The examples described by Steindachner measure up to 190 mm. in total length.

21 times. Upper surface of head, lips, teeth, &c. as in the preceding species. — 29 scutes 
in a longitudinal series, 15+ 14, all in front of the dorsal rather weakly carinate, the 
lateral keels obtuse and united posteriorly. Lower surface of head naked; abdomen 
with 3 series of plates between the posterior 4 plates of the lateral series ; the anterior 
plates smaller and more numerous, extending to the level of the middle of the gill- 
opening ; anal plate bordered anteriorly by 3, these 3 again by 5. First dorsal ray as 
long as the head; pectoral spine extending to base of ventral; ventral spine scarcely 
produced, the fin rounded, the second branched ray the longest; upper caudal ray 
elongate. Breadth of body at level of first anal ray 4 times in the distance from that 
point to the caudal. Body with 4 dark cross-bands; a series of blackish dots on the 
anterior pores of the lateral line; all the fins with dark spots on the rays; upper part 
of dorsal, base and posterior margin of caudal blackish, 
Total length 112 mm
