<br />Distribution: Green River at Jensen and Green River City; Colorado River
<br />at Moab.
<br />Remarks: This species known ai the "Colorado Salmon" becomes one of
<br />the largest fish in the waters listed, weighing from 10 to 20 pounds, with
<br />a maximum weight of 80 pounds. It is a good food fish.

<br />Remarks: We are in agreement with Prof. Snyder (1916)9 that C, Se11lillUda
<br />is a synonym of G, f"olntsta, We have been unable to find any specimens
<br />that agree with the Cope and Yarrow description. All our specimens are
<br />well covered with scales.

<br />
<br />Distribution: Common in the streams of Utah and Salt Lake Valleys.
<br />Remarks: It would seem that the genus Richardsonius shaull:! be used for
<br />our Utah minnows since they seem to be more closely related to such
<br />species as balteatus of the Columbia River system. There seems to be
<br />no good reason for making genera out of many of Gi.rard's .sub-genera.
<br />Dr. Hubbs of Michigan has examined specimens of thlS speCIes and be-
<br />lieves they should be placed in this genus.
