 I. Phoxinus (Tigoma) orcuttii sp. no v. 



Types, over one hundred specimens, the largest .062 m. in length. Te- 

 mecula River and tributaries. C. R. Orcutt, collector. Oct. 22, 1889. 

 Catalogue No. ion. 



While camping Mr. Orcutt discovered a large number 

 of fishes in a river about fifteen miles southeast of Tem- 

 ecula station. By using a blanket as a seine a number 

 were secured. Leaving out of consideration the Gaster- 

 ostciis niicroccphahts which enters rivers, but is properl}^ a 

 brackish water species, Ph. oraittii is the second* 'species 

 of fresh-water fish recorded from the western slopes of 

 San Diego county. Judging from its large sandy bed, the 

 river in which this species was discovered is evidently of 

 considerable size during the rainy season. hX the time it 

 was visited it was but three to five feet wide, and a few 

 inches deep. In places it disappeared entirely under the 

 sand. At Temecula station in the Temecula river this 

 species is still more abundant than in the mountains.
