oor REPORT OF THE COMMISSIONER OF FISHERIES. 
7. Leuciscus crassicauda (Baird & Girard). 
Coyote Creek. 
8. Rutilus symmetricus (Baird & Girard). 
San Francisquito, Madera, San Antonio, Campbell, Guadalupe, Coyote, Alameda, 
Arroyo Honda, and Isabel creeks. The apparent absence of this species from Stevens 
Creek is notable, as it occurs in smaller streams close by. It is able to maintain 
itself in Madera Creek during periods of drought, when nothing remains of the 
stream but a few small disconnected pools. 
The species being generally distributed throughout the Sacramento basin and sub- 
ject to considerable variation, measurements of a number of carefully preserved 
examples are here given: 
Measurements of examples of Rutilus symmetricus from streams tributary to the southern 
arin of San Francisco Bay. 
Alameda Creek Basin. 
Alameda Creek, Sunol.
