BRANNER-AGASSIZ EXPEDITION TO BRAZIL 1 83 



the lower very little produced in the others. The longest ray extends 

 beyond the middle of the anal, and is contained 2^ times in the length. 

 The color is light grayish-brown, finely mottled and with a number 

 of rather definitely placed round light spots with darker centers. The 

 most conspicuous of these form a series of five or six parallel with 

 the dorsal outline, and a similar series parallel with the ventral out- 

 line. Others occupy the intermediate territory. A narrow curved 

 dark bar extends from the upper eye obliquely across the interorbital 

 space to the lower eye, bounded by a light line in front and behind ; 

 another dark line and another light line may follow these. From the 

 front of the upper eye, a narrow scaleless area runs downward and 

 forward to the profile of the snout. This area is bounded above and 

 below by narrow, dark lines, which were probably dark blue in life. 

 The upper line ceases opposite the origin of the dorsal ; the lower ex- 

 tends down along the profile to the tip of the snout, and is continued 

 along the mandible to its joint. A dark streak — also probably blue in 

 life — runs along the back at the base of the anterior ^ of the dorsal 

 fin, on the colored side. This streak is formed of spots, one for each 

 ray, the hinder ones more or less coalescent. The dorsal and anal 

 fins are grayish, speckled with darker, a dark streak on the base of 

 each eighth to tenth ray. Pectorals not barred. The blue streaks on 

 the head have not been mentioned in any previous description of this 

 species. They are doubtless developed only in adult males. I find a 

 trace of them in a specimen from Jamaica (collector, Roberts).
