blotch just below the last dorsal rays, and another just 

 below the adipose. Markings of the female similar, except 

 that the broad lateral band is irregularly interrupted and 

 even reduced to a series of three or four backwardly 

 pointing V's in some. The satiny white stripe is lacking. 

 Dorsal tin in males reaching the adipose, when depressed; 

 reaching the anterior azygous plate in females. Pectorals 

 a little longer than the dorsal. Dorsal spine short, 2 in 

 the head. Side of the snout with stiff bristles in the male. 

 Snout long, 1.5 to 1.2 in the head. Eye small, 3 to 3.6 in 

 the snout, 5 to 5.5 in the head, and 1.4 to 2 in the inter- 

 orbital. Head a little greater than the depth, 3.4 to 3.5; 

 depth 3.5 to 3.6, D. I, 7-8; A. I, 5.5 to 6; lateral plates

rr. Head dark, with a worm-shaped mark on the snout; a large 

 unbroken spot on the lower part of the side between the 

 ventrals and anal. Dark stripe along the lateral line often 

 ending in a caudal spot; dorsal region checkered. Four 

 series of spots across the dorsal. Much like naltereri in 

 morphological characters (von Ihering).

 qq. Snout thickly sprinkled with small dark dots or distinct round 

 dark spots. 

 5. Head with very numerous small black chromatophores; 

 humeral processes dark; sides with a row of small dark 

 spots on either side of the lateral line, three very large 

 dark spots along the lateral line, a broken stripe along 

 the middle of the upper series of plates, sometimes 

 confluent in places with the large spots of the lateral 

 line, occiput, dorsal plate, and back just behind the 

 dorsal and adipose. Dorsal of male with five cross- 

 bars. Anal and ventral with a large central dark spot. 

 Pectorals cross- barred. Dorsal of the male reaching 

 beyond the adipose, not quite reaching the adipose in 

 the female. Pectorals reaching the tip of the ventrals 

 in the male, reaching the middle of the ventrals in 

 the females. Dorsal spine straight and strong, 1.1 

 to 1.2 in the head. Snout 2 in the head. Eye larger 

 than in kronei, 1.5 to 2 + in the snout, 3.5 to 4 in the 

 head, and 1.7 to 1.8 in interorbital. One or two azy- 

 gous plates. Head 3.3 to 3.5; depth 2.7 to 2.8; D. I, 7;
