(Jordan and Evermann, 1896, I, p. 807, p. 342.) 



This species was fonnd in abundance in San Diego Bay from 

 December to August, and unlike the other Atherinoid fishes it is 

 said to be connnon in the bay all the year. It has been taken as 

 far south as Magdalena Bay, Lower California (Gilbert, MS 

 notes). It is known northward to San Francisco (type locality), 

 and is abundant throughout its range. 



60. Atherinops insularum Gilbert. 

 (Jordan and Evermann, I, 1896, p. 807.) 



This is a species apparently confined to the islands from the 

 Santa Barbara Islands to Guadalupe Island, replacing Atheri- 

 nops affinis of the mainland. 



It has fewer spines in the dorsal (5) than Atherinops affinis, 

 finer scales (from 62 to 68), and a larger space between the dor- 

 sals. Dr. Gilbert (IMS. notes) has records of its occurrence at the 

 following localities: San Nicholas Island, Santa Cruz Island, 

 San Clemente Island, Cerros Island, and Guadalupe Island.

Not uncommon in San Diego Bay, especially abundant in a 

 brackish slough near Old Town. It is cosmopolitan in distri- 

 bution.
