MEDIALUNA. 



(Jordan and Evermann, 1898, II, p. 1391, fig. 560.) 

 Common on the coast of Southern California about rocky 

 places ; one specimen taken at La Jolla. Not seen in San Diego 

 Bay. Known from Santa Barbara (Jordan and Gilbert, 1880, 

 p. 456) south to Cerros Island (Jordan and McGregor, 1898, p. 

 279). 



92. Girella nigricans (Ay res). 



GREEN FISH. 



(Jordan and Evermann, 1898, II, p. 1382.) 

 The young up to ten inches in length are very abundant in 

 the tide pools. 



Color in life olive green with bi'i^ht blue borders to the fins 

 and membrane following the gill opening. The blue follows the 

 edge of the dorsal across the tips of the spines and rays, but fol- 

 lows the rays longitudinally on the upper and lower edges of the 

 caudal and on the front of the anal. The ventrals are tipped with 

 blue ; the pectorals are yellowish. There is a very conspicuous 

 light spot on the back below^ the middle of the base of the dorsal. 

 It is not at all constant in position, one being frequently behind 

 the other on opposite sides of the same fish. Sometimes there are 

 two spots on each side, and occasionally two on one side and one 

 on the other. When the fish has been dead a short time the blue 

 color on the fins entirely disappears, and the spot on the side is 

 not very conspicuous. 



Known from San Francisco south to Guaymas, Mexico (Ever-
