 p. 257 (1864). 



Length of head 4|- times in the total length. Breadth of head about 1\ times in 

 its length, diameter of eye about 8^- times, interorbital width nearly 4 times, length of 

 snout about If times. Sides of the snout, in the male, with bristles. About 33 scutes 

 in a longitudinal series, 15 + 18. Lateral keels sharp, serrated, the lower distinct on 

 the first scute. Lower surface of head covered with small plates except an area below 

 and behind the lower lip ; abdomen with 3 series of plates between the lateral series ; 

 an anal plate bordered anteriorly by 3. Length of first dorsal ray about 4-§- times in 

 the total length. Pectoral spine extending to middle of ventral. Caudal emarginate. 

 Breadth of body at level of last anal ray about 4 times in the distance from the latter 

 to the caudal. Fins with dark spots or bars. 



The type, from the Rio Cujaba, is about 280 mm. in total length.

Length of head 4-J — 5 times in the total length. Breadth of head If- If times in 

 its length, diameter of eye 7^-10 times, interorbital width 3f-3| times, length of 

 snout 1-g—lf times. Snout with a projecting rostrum ; supraorbital edges not raised. 

 32-33 scutes in a longitudinal series, 13-15 + 17-19; lateral keels weak, obsolete 

 anteriorly, remaining separate throughout or united posteriorly. Lower surface of 

 head covered with small plates except a naked area below and behind the lower lip ; 

 abdomen with 3 series of plates between the lateral series ; an anal plate, bordered 

 anteriorly by 3, these 3 again by 4. Dorsal elevated, its height 3-4 times in the total 

 length. Pectoral spine extending nearly to middle of ventral or beyond, to anal 

 opening (young) or to origin of anal fin (adult}. Caudal emarginate, the outer rays 

 much produced. Breadth of body at level of last anal ray 6f- 7^ times in the distance 

 from the latter to the caudal. Olivaceous; a blackish area in front of each eye; 

 dorsal with dark spots on the rays, the first and second interradial membranes blackish ; 

 caudal dark at the base and with a dark longitudinal stripe on each lobe. 



Bio Magdalena, Panama. 



After examination of the type of L. panamensis, which is 98 mm. in total length, 

 I have no doubt of the identity of L. aurea, recently described from a specimen of 

 169 mm. from the R. Magdalena, with this species. Still larger examples (250 mm.)
