condition, from which, I suppose, arose the deeper tint and 
greater extent of the rosy tint on their side and belly; back 
paler olive; spots fewer and chiefly near the tail, where they 
assumed a more stellate arrangement, but this was not con- 
stant. Very young specimens, four to five inches long, were 
barred on the sides. I saw none so small on the east slope. 
No. 61, Little Blackfoot River, August 17th. No. 69, near 
crossing of Bitterroot River, September 2nd. Length, 14.75 
inch; olive, below silvery with rosy tints towards sides; 
spots black; operculum, etc., bronze gilt; chin-mark orange. 
Salmo sp.—A single specimen of a species of trout was 
caught by Lieut. A. V. Kautz, U.S. A., on September 25th, 
just below the ferry across the Spokan River, at Antoine 
Plant’s. Its very dark hue corresponds to the color of the 
stream, which is often the case in fish of the same species 
found in different localities, but it otherwise differs very much 
from the preceding. There is a high fall of the river below 
this point not passed by the salmon, so that this species cannot 
be a hybrid with them or anadromous either. No. 121, dried 
skin; colors when fresh were very dark olive above; belly 
dull white (no rosy marks) ; chin-mark reddish purple ; oper- 
culum coppery, with a deep purple tint, this continuing as 4 
broad streak along lateral line. Form of head very obtuse.* 
SUCKLEY’s SALMONTROUT (S. Suckleyi Cooper, nov. sp-): 
*Besides Salmo Lewisii, the following fish were caught at and near Fort Benton, 
most of ge probably, do not go above the falls: 
PIKE PERCH (Stizostedion boreus Gir.). Not very co 
CATFISH. Pimelodus olivaceus Gir. was the only ca Perg seen above Fort Union, 
below which P. ailurus Gir. is common. It is excellent eating, preferred by many to 
‚trout, which cannot be said of other c. atfish 

RIVER SUCKER (Acomus lacta. rius Gir.). Common and =y Pega eating. 
MISSOURI KER. ( Catostomus Suckleyi Gir.). Not very com 
NEBRASKA DACE communis Gir.). Abundant below. Fort Benton, but 
MISSOURI HERRING vases no Lesu.. Common, and bites sharply like 8 
trout, giving zood sport, but 
SHOYEL-NOSED STURGEON tae platirhynchus Baird). Several were | 
caught near Fort Bento
