‘AmpBnopLites RupESTRIS, Raf. Rock Bass. 
This favorite and widely distributed species does not differ from 
the other fishes mentioned in respect to the food of the young. The 
smallest specimen examined, five-eighths of an inch long, contained 
only a few Cladocera (Pleuroxus). Another, three-fourths of an 
inch long, had eaten daphnids (seventy-five per cent.), Cyclops 
(ten per cent.), and larve of Chironomus. A third, seven-eighths 
of an inch long, contained only minute fragments of a few larve of 
‘Neuroptera. ‘These specimens were all taken from Fox River, in 
July, 1879. The remaining young of the yéar were living chiefly on 
Corixa (eighty-three per cent.), as were also the young of the year 
‘preceding (ninety per cent.), as fay as could be judged from the 
food of two specimens, from three to four inches in length. Some 
land insects, ephemerids, water beetles,. and a few Allorchestes 
‘were also found in the food. 
Four adult specimens, taken at Ottawa, on the 8th of July, had 
featen some minute fishes (fifteen per cent.), a few water beetles, in- 
‘eluding Tropisternus limbatus, over forty per cent. of Neuroptera 
darve, and about thirty per cent. of smmall crawfishes. The Neurop-
