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 3 

 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 3 again by 5. First dorsal ray about f 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 4-jj 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. 



Eastern Brazil, from the R. Preto to the R, Parahyba.

Length of head about 4-^ times in the total length. Breadth of head about 1-f times 

 in its length, diameter of eye 7 times, interorbital width 4-g- times, length of snout 

 2j 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.
