5.3 in the length. Ventrals inserted directly below or slightly anterior to origin of dorsal, their tips 
when depressed extending to base of second anal ray. Pectorals a little longer than ventrals. 4.5 in the 
length. Caudal deeply forked, 4 in the length. 
According to Mr. Cramer’s notes the color in life is pale olive overlaid with silver; a fairly con- 
spicuous silver band extending along the side to base of caudal; upper parts of body speckled with 
black, the specks grouped here and there in clusters; scales on dorsal half of body narrowly edged 
with dusky; top of head dark, a narrow, median dusky band extending from occiput to dorsal fin. In 
spirits the color changes to light brown, the silver partly disappears, and an inconspicuous dusky band 
is seen along the side, most evident posteriorly. 
This description, except the life color, is of the type, no. 61574, U. S. National Museum, a specimen 
65 mm. long from the Willamette River at Oregon City, Oreg., Messrs. Frank Cramer and K. Otakt, 
collectors. Cotype no. 9863, Stanford University. Named for its discoverer, Mr. Frank Cramer. 
The barbel is sometimes absent from one or both sides. Among 35 specimens from ‘‘The Lakes,”’ 
near Albany, Oreg., 3 are without barbels. There is also some individual variation in the color, the 
small spots on the sides sometimes forming in longitudinal lines. Besides the specks which are massed 
together to form rather distinct spots there are isolated ones of large size occurring most frequently 
below the lateral line. The appended table shows some variations of a local character, the anal fin 
being lower and the caudal shorter in the specimens from the Willamette basin. Short fin rays are 
not characteristic of individuals from the Willamette, however, as in 10 specimens from ‘“‘The Lakes”’ 
the anal averages 0.2 and the caudal 0.3 of the length. 
Willamette and Umpqua basins.
