FISHES OF THE FAMILY LOEICAEIID^. 281 



lateral keels obtuse, united posteriorly. Lower surface of head naked. Abdomen with 

 3-4 series of plates between the posterior plates of the lateral series, 5 or 6 series 

 between the middle ones, the anterior plates still smaller, extending to the level of the 

 inner angle of the gill-opening; an anal plate, bordered anteriorly by 3, these 3 again 

 by 5. First dorsal ray nearly as long as the head ; pectoral spine extending a little 

 beyond origin of ventral ; ventral spine not produced, the first branched ray the longest ; 

 upper ray of caudal produced. Breadth of body at level of first anal ray about 5 times 

 in the distance from that point to the caudal. Body with 5 dark cross-bands, the first 

 passing through the base of dorsal ; all the fins with dark spots on the rays. 



Total length 80 mm. 



Four specimens : Bolivia ; Argentina. 



12. LORICARIA KONOPICKYI. 



Loricaria konopickiji Steind. Denkschr. Ak. Wien, xli. 1879, p. 45, pi. vi. fig. 3, and pi. vii. fig. 1. 



Length of head about 4f times in the total length. Breadth of head If times in its 

 length, diameter of eye 6|- times, interorbital width 4 times, length of snout 2\ times. 

 Supraorbital edges slightly raised ; supraoccipital with a pair of obtuse keels ; orbit 

 with a large notch ; lips papillose, with short marginal fringes, the lower of moderate 

 breadth, rounded ; barbel slightly longer than the diameter of eye ; teeth well developed, 

 9-10 on each side in both jaws. 29 scutes in a longitudinal series (15 + 14), the lateral 

 keels obtuse, completely united posteriorly ; all the scutes in front of the dorsal carinate. 

 Lower surface of head naked ; abdomen with 3 series of plates between the lateral 

 series, the anterior plates scarcely smaller, extending to the level of the middle of the 

 gill-opening; an anal plate, bordered anteriorly by 3, these 3 again by 5. First dorsal 

 ray 1+ times the length of head ; pectoral spine extending to anterior \ of ventral ; 

 caudal emarginate ("? the uppermost ray elongate). Breadth of body at level of first 

 anal ray 4^-4f times in the distance from that point to the caudal. Back with 5 or 6 

 dark cross-bands, the first through the base of the dorsal ; head and anterior part of 

 body with small blackish spots ; all the fins with dark spots on the rays ; caudal dark 

 at the base and with a dark intramarginal band. 



The type, from the Middle Amazon, is about 108 mm. in total length. I have 

 received an example of nearly the same size from Rio Janeiro, through the Geneva 

 Museum.
