Mat, 1893.] FISHES OF THE DEATH VALLEY EXPEDITION. 231 



posteriorly, and ending in an obscure black spot on base of tail. A 

 dark stripe sometimes present along middle of lower half of sides. 



Numerous specimens were procured in the warm springs at Ash 

 Meadows, Indian Creek, and Vegas Creek, Nevada. 



Rutilus synimetricus (Baird and-Girard). 



Type locality. —Old Fort Miller, Fresno Co., San Joaquin Valley, California. 



Specimens from Owens Lake, California, seem to agree with those 

 reported on by Jordan and Henshaw (Leucos formosus, Eep. Chief En- 

 gineer, Wheeler Surv. W. 100th Mer., App. NN, 1878, 193) from Washoe 

 Lake, Nevada, and Kern Lake, California. There are 11 scales between 

 lateral line and front of dorsal, and 52 scales in lateral line. Teeth 4-5. 

 There are seven or eight rays in the anal fin, and the head is 3§ in the 

 length. The lateral line is imperfect in the young. 



The American species of this genus are poorly defined, and may be 

 reducible to one or two species. If the specific forms prove to be 

 numerous there is uo assurance that these specimens are identical with 

 the types of Pogonichthys synimetricus and Algansea formosus from the 

 San Joaquin and Mohave rivers. 



Lepidomeda vittata Cope. 



Type locality. — Little Colorado River, Arizona. 



Three small specimens from Pahranagat Valley, Nevada, agree well 

 with the original description of this species, and are probably referable 

 to it. It has been recorded hitherto only from the original locality, 

 the Colorado Chicpiito River, Arizona, and its occurrence in the present 

 locality is full of interest. Not only Lepidomeda but the whole sub- 

 family (the Plagopterince) to which it belongs, is peculiar to the basin 

 of the Colorado River, to which the Pahranagat waters must belong. 



Cyprinus carpio Linn. 



A specimen of this introduced species was found dead on the shores 

 of Owens Lake. Carp and catfish are both common in the lower Owens 

 River, and when they enter the lake are soon killed by the alkalinity of 

 the water. 



Mr. Palmer and Dr. Fisher reported carp as the staple food fish at 

 Three Rivers on the Kaweah River, where numerous large individuals 

 were taken. 



Salmo irideus Gibbons. 



Type locality. — San Leandro Creek, Alameda Co., California. 



A single specimen of the ' Rainbow Trout' was preserved by Dr. A. 

 K. Fisher from the Canon of Kings River. Compared with specimens 

 from the Santa Cruz Mountains in the vicinity of Palo Alto, this is 

 found to agree in all respects. The coloration is very bright as is usual 

 in the colder mountain streams. The scales above the lateral line are 

 arranged in 135 oblique series.
