ine of these, or 40 p ni. are large enough to be 
ue on a hook and the t opi or 55 per cent., are too small 
to be taken in that way. Of the species that have disappeared, 
three small and two large ones were formerly abundant in 
the stream, three small ones were rare and the abundance of 
the others is not noted. Atogether, twelve of the nineteen 
species are either abundant or at least of common occurrence 
in this region, while the other seven are not very common. 
Classified on the basis of food*, eleven of the extermi- 
nated species subsisted chiefly on animal food, five are either

terus scierus, was first described from this stream and has 
since been taken in several states of the Mississippi basin, but 
is not as common as many of the darter family, of which it is 
a member. The other is the sucker-mouthed minnow, Phena- 
cobius mirabilis, not heretofore reported from Indiana, but 
rather common oe Illinois and farther west. Apparently it is
