Evermann — A New Trout from Lower California. 21 



seasons the stream sometimes reaches the coast. A few hundred 

 yards below the springs are some large, deep pools. These fish 

 abound throughout the entire length of the stream. 



La Purisima Creek is a stream about 50 feet wide and 18 

 inches deep, flowing for 20 or 25 miles down a broad, fertile 

 canyon in which is located the settlement known as La Purisima, 

 about 35 miles south of Mulege, or in north latitude 26°. This 

 stream flows to the Pacific after heavy rains, but it usually loses 

 itself in the sand and is there restricted to the middle of the 

 peninsula. The large goby was found here. 



It has never been definitely determined just how far south 

 trout originally extended in the coastal streams of southern 

 California. It has been said that trout are native to a stream 

 near San Luis Rey in the northern part of San Diego County, 

 but the authority for the statement is not known. 



A new species of trout* has recently been discovered in the 

 headwaters of South Fork of the Santa Ana River at an altitude 

 of 8,200 feet, near San Gorgonio Peak in the San Bernardino 

 Mountains; and rainbow trout have been introduced into the 

 lower portion of the Santa Ana as well as into many other 

 streams in southern California. A comparison of the specimens 

 of the San Gorgonio and the San Pedro Martir trouts shows 

 them to be very distinct species. 



The most .southern stream in California in which 1 have per- 

 sonally taken native trout is Santa Paula ('reek, Ventura County, 

 about 200 miles north of the International boundary, or 300 

 miles from the stream in which the Lower California trout are 

 found. Other small streams in Ventura County contain trout; 

 namely, the Sespi, Sisa, Matillija, and perhaps others, all small 

 streams which dry up in their lower courses during the summer 

 and fall. The trout in these streams is a small species, seldom 

 exceeding 6 or 8 inches in length, brightly colored and possibly 

 identical with the typical rainbow trout, Salmo irideus. 



Trout have been reported from at least three other localities 

 in Mexico besides the San Pedro Martir Mountains of Lower 

 California. 



In 1886, Copet recorded trout from Mexico in the following
