Doydixodon 



This genus contains several species, chiefly on the east coast of 

 Asia. Only one species, Girella nigricans, is found on our coast. 

 This species, called the green-fish, occurs on the California coast from 

 Monterey to Cape San Lucas and Guaymas. It reaches a foot in length, 

 is a common and active inhabitant of rock-pools, and is a food-fish of 

 fair quality. In life it is dusky green, paler below ; fins dusky greenish ; 

 young with a large yellowish blotch on the back on each side of dorsal. 



GENUS DOYDIXODON VALENCIENNES 



This genus is very close to Girella, from which it seems to differ 

 in having the soft dorsal and anal elevated, and only 12 or 13 dorsal 

 spines. The single species in our waters is D. freminvillei, a very 

 rare species known only from the Galapagos and the coast of Peru. 



GENUS HERMOSILLA JENKINS &■ EVERMANN 



This genus is allied to Kypliosus, from which it differs in the 

 weaker gill-rakers, the entire preopercular margin, absence of teeth on 



tongue, the larger scales, and the less complete squamation of the head. 

 But one species is known, H. a^urea, which occurs at Guaymas
