I20 REPORT OF NEW JERSEY STATE MUSEUM. 

 2. Further Notes on New Jersey Fishes. 



My observations on the fishes of the State during the past 

 season, or since my supplement in last year's report was prepared, 

 are all recorded in this paper. In a recent number of Science, 

 the interesting discovery of "Gambusia in New Jersey" is noted. 

 This is a small fish of interest chiefly to mosquito investigators 

 for its destruction of the larvae of the malarial mosquito, Ano- 

 pheles. Other rare and interesting species have been found in 

 New Jersey waters and examined. In Professor J. B. Smith's 

 Rep. N. J. Agr. Exper. Sta., 1904, I have previously neglected 

 to call attention to Mr. William P. Seal's interesting notes on the 

 mosquito-devouring fishes. Dr. W. C. Kendall, of the Bureau 

 of Fisheries, Washington, D. C, has kindly furnished me with 

 some interesting notes. 



Family PETROMYZONID^. 



Petromyzon marinus Linnaeus. 



Lamprey. 



Reported to occur in Cedar Swamp Creek at times about 

 Petersburg, though in tide-water. 



Mr. J. B. Vanderveer reports that in his experience the lamprey 

 is quite bold when spawning, and resists intrusion, though harm- 

 less. Their bodies appeared in contact when the ova was ex- 

 truded. He found them in the Delaware about Trenton in early 

 summer, though small, and ascending or swimming with the 

 common eel, Anguilla. On one occasion three were seen on a 

 single shad, of which one was fastened on each gill-opening and 

 the other at the vent. 



A small example in the Antmoccctes stage was taken in Ed- 

 ward's Run, tributary of Mantua Creek, in Gloucester county, 

 November 3d, 1907, by B. W. Griffiths and H. W. Fowler.
