2 in the head; caudal notched, the upper lobe much longer, nearly or quite equal 

 to the length of the head; anal reaching lobe of caudal, ventrals to anal; pectorals 

 not to ventrals; pectoral spine less than half the length of the head, its inner margin 

 with strong recurved hooks, its outer margin with still larger teeth, antrorse near 

 the tip, retrorse near the base. 



Black, with markings of brown, the lighter color forming a blotch on the 

 sides, below the space between the dorsal and a few smaller irregular ones in front 

 of it ; adipose and upper surface of caudal peduncle and a spot on or near the lower 

 surface of the peduncle also light brown. Dorsal black, its margin and a wedge 

 entering the posterior rays hyaline; caudal with a median spotted area near its 

 base, the margin white, the rest of the fin black; anal, ventrals and pectorals each

No specimens of this species were secured by me. The specimens mentioned 

 by Giinther as from the Essequibo do not belong to this species. I examined the 

 types. Three specimens, 91-110 mm. " De la Mana, Leschenault," in the Jardin 

 des Plantes. 



Dorsal plate long, nearly touching the occipital process. Dorsal spine smooth; 

 pectoral spine with strong teeth in front and behind, as wide as the spine. 

 Maxillary barbel reaching a little beyond the tip of the humeral spine; a band be- 

 tween the gill-openings, a submedian band on the last dorsal rays, tips of rays 

 hyaline, anal similar, base and subterminal band of caudal dark. 



Two of the specimens are nearly uniform dark brown, one has a very distinct 

 band between the gill-openings, and all have the entering wedge of light on the 

 dorsal and anal and have the vertical fins margined with white. Villose as in 

 villosus. 



All have backward projecting angles to the premaxillary bands of teeth.
