KO. 2333. FISHES FROM OWUNS RIVER— SNYDER. 205 



In 20 examples the scales in the lateral series number 60 to 67 ; 

 between occiput and insertion of dorsal 37 to 42; above lateral line 

 12 to 14; below lateral line 9 or 10. 



Mr. Kennedy remarks : 



Tliis species is not common. It varies much in color, often being olive brown 

 above, occasionally more gray than olive; yellowish white below. The side stripe 

 is in some cases very conspicuous, in others obscure. The small, yellowish eye dis- 

 tinguishes this fish among others. 



CYPRINODON MACULARIUS Baird and Girard. 



SPOTTED PURSY MINNOW. 



This little fish occurs in the shallow pools along the river. It 

 abounds in the bog pastures and tulle swamps, and enters the irriga- 

 tion ditches in large numbers. Wlien undisturbed it swims about 

 after the manner of top-minnows, the mouth at the surface, the tail 

 deeply submerged. 



Mr. Kennedy reports that the swampy areas of Owens River are 

 relatively free from mosquitoes, and suggests that their absence is 

 probably due to the activities of this fish. The suggestion is well 

 worth serious attention, and if investigation proves that the species 

 aids in controlling the pest m this place, its introduction should 

 be attempted in swampy and irrigated regions where mosquitoes 

 abound, parts of the Sacramento Valley, and the lower Humboldt 

 River, for example.
