Not a trace of fishes was found in the stomachs of these speci- 
mens; and this fact, together with the large percentage of molluscan 
food, constituted the leading alimentary peculiarities of the species. 
The first of these is doubtless related to the small mouth,—the 
second to the stout, blunt pharyngeal teeth, —a character used in 
defining the genus. In all the preceding species the pharyngeals | 
are set with more slender, pointed teeth. 
Evromotis pauitipus, Ag. Pane SuN-FISH. 
Having but few specimens of this rather uncommon species, I 
have examined the food of but one,—-enough to indicate that it 
probably agrees closely with the preceding species. 
This fish, taken in Clear Lake, Ky., had eaten largely of small 
Mollusca,—young Unionidew, Planorbis, Amnicola, ete. These 
amounted to seventy-five per cent. of the food. The remaining ele- 
ments were Chironomus larve, several small water beetles, (Hy- 
droporus hybridus, Cnemidotus 12-punctatus, and Haliplus, sp.), an un- | 
krown aquatic pupa and a little pond-weed.
