some specimens present a sort of transversely barred effect, while 

 others are indistinctly striped. 



"Much red and orange about lower parts of head. Rows of red 

 spots between the fin rays of the caudal and on the rays of the pectoral" 

 (Evermann and RadclifFe). 



Only two specimens, 145 and 190 mm. (113 and 150 mm. to base of 

 caudal) long, from Peru are at hand. The smaller one was taken in 

 Lobos de Afuera Bay by the Mission, and the larger one at the island 

 by the same name by R. E. Coker. The proportions and enumera- 

 tions stated first in each instance are based on the smaller specimen. 

 Several specimens form the Galdpagos Islands, the tj^pe locality, a few 

 small ones from Gorgona Island, Colombia, several from Panama 

 Bay, and one from Acapulco, Mexico, have been compared. Although 

 there is great variation in color, struc:ural differences were not 

 detected. 



Range. — Gulf of California to the Galapagos Islands and northern 

 Peru.
