 River and streams at)out Puget Sound. It apparently fully iutergrades with the preceding, the 

 anal rays ranging from 11 to 22. The name Leuciscus lateralis is preoccupied, and this form, if dis- 

 tinct, should stand as Leuciscus yilli.

 (13 to 10). Teeth 2, 4-5, 2. Scales 11-60-7, 32 before dorsal. Body deep, compressed, much
