242 REPORT OF THE COMMISSIONERS OF 



463. Silver fins (Notropis whiplii Girard). — Fifty caught, most in the latter part of 

 May and the first half of June. 



471. Red fins (shiner, dace) {Notropis cornutus Mitchill). — One hundred and thirty, 

 nearly all of which were taken during the first half of June. 



559. Cut-lips (Exoglossum maxillingua Le Sueur). — Four collected. Common 



707. Alewife or sawbelly (Pomolobus pseudoliaroigns Wilson). — One hundred and 

 fourteen, most of which were taken in one school on the afternoon of May 23. 



799. Rainbow trout (Salmo irideus Gibbons). — Only two of these were captured, 

 but one was fifteen inches long, and others even longer were caught in the Inlet by 

 various anglers. This indicates gratifying success in the efforts of the United States 

 Fish Commission to introduce this species of fish from the West Coast. 



801. Brook trout (Salvelinus fontijialis Mitchill). — Nineteen were taken from the 

 trap. They evidently were not in schools, and were not " running " at this time of 

 year, but were merely passing from one feeding ground to another. 



942. Pike (Lucius lucius Linnaeus). — Only one was seen, but this was remarkable 

 for the fact that it was a large female measuring over three feet in length, and was 

 filled with ripe eggs, which stripped readily. As this was at the close of the pike's 

 spawning season for this region, this definite observation was enough to prove that the 

 representatives of this species may ascend streams to spawn here as late as the middle 

 of April. 



959. Barred killifish (Fiindulus diaphanus Le Sueur). — Three caught. 



1 169. Trout perch (Peiropsis guttatus Agassiz). — Sixty caught. Light is here for 

 the first time thrown upon the spawning habitat and period of this unusually 

 interesting and generally rare fish. The trout perch is so named because it has many 

 features that partake of the trout, on one side, and ally it to the perch on the other. 

 It thus stands intermediate between the soft-rayed and the spiny-rayed fishes. It is 

 a living vestige of the fish fauna of a past geological age. Nearly all that were caught 

 were taken during the month of May, at which time they were in ripe spawning 

 condition, showing that they run up streams here to spawn during that month. It is 

 so rare that many naturalists of high reputation who visited our weir had never 

 before seen it alive. In fact, in Dr. Meek's " Fishes of the Cayuga Lake Basin," 

 published in the "Annals of the New York Academy of Science," in 1889, he said: 

 "I have seen no specimens of this species from the lake." 



141 3. Rock bass (Amblopites rupestris Rafinesque). — Ninety -nine, caught mostly 

 in the latter part of May and the month of June, which indicates their time and place 

 of spawning here. Many taken at this date were adult males or females, and were 

 evidently going up stream to spawn.
