below Portageville Falls. June 18, Brimer brook (Allegany Co.). 2 9/lt) 

 inches. Food: 3 small midge larvae [Chironomidae) . Fan-tailed darters 

 were taken with eggs at several places. June 25, Pliillips creek (Allegany 

 C!o. ) . There were about 400 eggs, fastened side by side to the under side ol a 

 Hat stone in shallow water where the current was moderate. The eggs 

 were spherical, 3/32 inches in diameter and the egg mass formed a round 

 patch on the stone. As the mass and its attachment were lifted from the 

 water some eggs hatched, possibly due to the warmth of the sun. The young 

 were i/4 inch long and had a ratlier small yolk sac. They were very active 

 and quickly sought shelter under stones. Due to dark spots on the body 

 they were inconspicuous when in the water. A male darter 2% inches long, 

 probably the parent, was found under the stone which bore the eggs. The 

 water temperature was 08° F. June 22, Cryder creek (Allegany Co.). Egg 

 mass about 2 days from hatching and male taken under stone in swift, shallow 

 water. Water 00° F. July 0, Angelica Genesee — 2 (Allegany Co.). Egg 

 mass (hatching) and male found under stone in shallow water. Water 76'° 

 F. 



Etheostoma hlennioides Rafinesque. — Green-sided darter. Genesee river and 

 some of largest tributaries as Black creek (Monroe Co.), Honeoye creek 

 (Monroe Co.). Warm waters. Rapids or swift shallow water with hard 

 Ijottom. Moderately common in the Genesee river from Belmont to Black 

 creek ( Monroe Co. ) . June 29, Genesee river below Belmont dam. 2 inches. 

 Food: 3 midge larvae [Ghironomidae) and 1 crustacean {Ostracoda) , Con- 

 tained a trace of vegetable matter (diatoms). 



SciAENiDAE Drum-fishes 



Aplodinotus grunniens (Rafinesque) . — Sheepshead, fresh water drum. One 

 specijuen was said to have been caught from the dock of the Oak Hill Boat 

 CIul) (Rochester). It is possible for some Great Lakes species to enter the 

 river via the Erie canal. 



CoTTiDAE Sculpins 



Cottiis hairdii (Rafinesque). — Sculjjin, Miller's Thumb, Blob. Moderately 

 small shallow, swift streams witli ruljble or rock Iwttoni. Occurs in warm 

 or cold waters but seems to avoid large waters such as the Genesee river. 

 June 18, Brimer brook (Allegany Co.). 1% inches. Food: 2 yomig caddis 

 worms and their cases (Trichoptera) , a mayfly nymph (Ephemerida) , and a 

 small amount of filamentous algae and diatoms. July 6, Tributuary of 

 (Janeadea creek (Allegany Co.), 2% inches. .Food: 2 mayfly nymphs 

 {('hiroteuetes, Heptagenia) , 3 midge larvae (Chironomidae), and a small 

 fiagment of algae. June 20, Nigger spi'ing (Allegany Co.) Messrs. F. B. 

 Smith and P. E. Hering found a s('ul})in with its egg mass. The eggs were 

 splierical, Vs inch in diameter and yellow. They were in a grape-like mass of 

 approximately 200 eggs, attached to the under side of a stone. A 3^ inch 

 fish ft)und with them was probablv the male parent. The water temperature 

 was 48° F.

 tlie Genesee river at Gold (Potter Co.), Pennsylvania, (Fowler 1907). Should 

 occur in the Genesee drainage within New York State though not taken
