FISHES OF THE MISSOURI RIVER BASIN. 351 



Vol. ii, p. 362: "June 11. One of the meu caught several dozen fish of two species. 

 The first is about nine inches long, of a white color, round in shape; 

 the month is beset both above and below with a rim of fine, sharp 

 teeth, the eye moderately large, the pupil dark, the iris narrow, and 

 of a yellowish brown. In form and size it resembles the white chubof 

 the Potomac, though its bead is proportionally smaller. These read- 

 ily bite at meat or grasshoppers; the flesh, though soft and of a line 

 white eolor. is not highly flavored. The second species is precisely of 

 the form and aboul the size of the fish known by the name of hickory - 

 shad or old-wife, though it differs from it in bavin-- the outer edge of 

 both the upper and lower jaw set with a rim of teeth, ami the tongue 

 ami palate also defended by long, sharp teeth bending inward ; the eye 

 is very large, the iris wide, and of a silvery color. These do not 

 inhabit muddy water, and the flavor is much superior to that of the 

 former species. Of the first kind we have seen a, few before we reached 

 .Marias River; but had found none of the last before we caught them 

 in the Missouri above its junction with that, river." This locality was 

 near the mouth of Marias River. The first species is Stizostedion cana- 

 dense boreum, and the other either Hiodon alosoides or Hiodon tergisus. 

 Vol. it, ]>. 367: "June 13. In the afternoon they caught in the falls some of both 

 kinds of the white fish, and half a dozen trout from 16 to 23 inches 

 long, precisely resembling in form and in the position of the fins the 

 mountain orspeckled trout of the United States, except that the specks 

 of the former are of a deep black while those of the latter are of a 

 red or gold color. They have long, sharp teeth on the palate and 

 tongue, and generally a small speck of red on each side behind the 

 front ventral tins; the flesh isof a pale yellowish red, or when in good 

 order of a rose-colored red.'' This locality is the lower or Crooked 

 Falls of the Missouri, below the present town of Great kails. Montana,. 

 The two kinds of " white fish" were probably Ictalurus punctatus ami 

 Hiodon alosoides, and the trout, of course, was Salmo mykiss lewisi. 

 Vol. n, p.-373: The next day and at the same place they "obtaineda number of fine 

 trout and several small catfish, weighing about four pounds and differ- 

 ing from the white catfish lower down the Missouri." These were 

 probably not different from the other white catfish. 

 Vol. ii. p. 431: "July 20. Since the river has become shallow we have caught a 

 number of trout and a fish white on the belly and sides, but of a bluish 

 east on the back, with a long, pointed month opening somewhat like 

 that of a shad.'' This was in the Missouri nearly due east of Helena. 

 The fish were Sahno mykiss lewisi and probably Hiodon alosoides. 

 Vol. if. p. 458 : '■ August :'.. The only fish observed in this part of the river were the 

 trout ami a species of white fish with a remarkably long, small mouth, 

 which one of our men recognized as the fish called in the Eastern States 

 the 'bottlenose.' " This was in Jefferson Fork of the Missouri, near the 

 mouth of Whitetail Deer Creek, south of Helena. The trout was Salmo 

 mykiss lewisi; the "bottlenose" is not identifiable; if may have been 

 Coregonus williamsoni cismontanus or Pantosteus jordani. 

 Vol. ii, p. 495 : "August 13. Some very tine trout [ Salmo mykiss leivisi] were caught, 

 as also for several days past." This was in Beaverhead River near the 

 mouth of Grasshopper Creek, south of Dillon, Mont. 

 Vol. Hi, p. 1138 : "July lb. One of the men caughi a fisb which they bad not seen 

 before. It was eight inches long, andresembeda trout in form, but its 

 month was like that of a sturgeon, and it hail a red streak passing on 

 each side from the gills to the tail." This locality was in the Yellow- 

 stone River near the mouth of Little Timber Creek, some 30 miles below 

 Livingston, Mont. The fish was undoubtedly a sucker, and almosi cer- 

 tainly the species named Pantosteus jordani S7 years afterward. There 

 is, of course, a possibility of its having been Catostomus catostomus.
