THE SHORE FISHES OF PERU 345 



mens are considerably darker, with correspondingly darker fins. ^ 

 The two large males among the Panama material and one from Socorro 

 Island differ in color only in the absence of the dark longitudinal stripe 

 on the side. Large males have a pronounced fleshy pad on the head 

 over the eyes. In large examples, whether male or female, the outer 

 rays of the caudal and the lobes of the dorsal and anal become very 

 long, often exceeding the length of the head, the lobes of the dorsal 

 and anal reaching well beyond base of caudal. The outer rays of the 

 ventral, too, become much elongated, sometimes reaching origin of anal. 

 The usual number of enlarged teeth anteriorly in each jaw is four 

 above and four below, and they are scarcely compressed in any 

 individual examined, being rather strictly canine-like. 



Range. — Baja California to Peru. Reported also from the Gala- 

 pagos Islands.

The foregoing proportions and enumerations are based on four 

 specimens, 130 to 245 mm. (106 to 202 mm. to base of caudal) long, 

 taken by the Mission in rocky places in Paita Harbor, Lobos de Tierra 

 Bay and Lobos de Afuera Bay. These specimens are so closely 

 related to those already described as B. diplotaenia that it seems 

 necessary to point out only the differences noticed. The most 

 prominent one is the much darker color, the four specimens of B. 

 eclancheri being uniformly dark brown, varying little among them- 

 selves, only one being a little lighter brown than the others. The 

 fins, too, are quite dark, only the basal part of the pectoral being 

 olivaceous in the three dark specimens. In the somewhat lighter 

 specimen most of the pectoral and the caudal are somewhat oli- 

 vaceous. According to the accounts offered by Evermann and Rad- 

 cliffe (see reference above), some specimens are marked with a black 

 bar on the head, which is not evident in any specimen at hand. In 

 the report of the Mission (1943, p. 22) black individuals, red and brown 

 ones, and partly orange, yellow, and white ones are mentioned.
