 LOWER CALIFORNIA.

While carrying on biological explorations in the peninsula of 

 Lower California in 1905 for the U. S. Bureau of Biological 

 Survey, Mr. E. W. Nelson collected a few specimens of fishes. 

 Through the courtesy of the Biological Survey these have been 

 placed in my hands for identification. Although the collection 

 is a small one, containing but 37 specimens representing only 

 5 species, it is of unusual interest because the specimens come 

 from localities in which little or no collecting had previously 

 been done, and because 2 of the species, a trout and a cyprino- 

 dont, prove to be new and undescribed. 



The localities represented in the collection are four, namely: 

 the San Ramon River, a small stream at San Ignacio, La Puris- 

 ima Creek, and some small tide pools at San Felipe Bay. 



Mr. Nelson has furnished the data for the following account 

 of these various waters: 



The Rio San Ramon has its rise at an altitude of about 7,000 

 feet in La Grulla meadows on the west side of the San Pedro 

 Martir Mountains, about 150 miles south of the International 

 boundary, and descends through a deep, narrow and precipi- 

 tous canyon to the vicinity of San Antonio ranch. Below 

 San Antonio the descent is more gentle and the stream winds 

 through a rocky canyon most of the way to the sea. The San 

 Ramon River is merely a small creek during ordinary times, but 

 becomes a torrent during heavy rains. It is said to be the only 

 stream in northern Lower California which always flows to the
