it is known to be present in New York State in the following 

 streams : 



1. Inlet of Cayuga lake. 



2. Inlet of Seneca lake (secured by Gage in 1894). 



3. Cassadaga creek, a tributary to the Alleghany river (speci- 

 mens and information supplied by V. D. Smith). 



4. Chaclakoin creek, the outlet of Chautauqua lake, and tributary 

 to the Alleghany river (information given by Dr. G-. W. Cottis of 

 Jamestown, N. Y.). 



5. Spring creek, a tributary to Cattaraugus creek, which finally 

 empties into Lake Erie (information by Dr. E. H. Eaton of 

 Hobart College, Geneva, N. Y.). 



6. In 1897 Dean and Sumner found brook lampreys in Tibbits 

 brook, Lincoln Park, New York City. Their account of the spawn- 

 ing of these lampreys is most excellent, and the picture which 

 they published of them building their nest and spawning "Shak- 

 ing together" is the best representation ever published (Fig. 3). 



Doubtless brook lampreys are present in many other streams 

 of the State. As their free-swimming life is only during the 

 spawning season, which is very short, it is quite intelligible that 

 they may have been missed in brooks where they are actually 

 present. Furthermore the water is likely to be rather high and 

 turbid in April and May when they spawn, and a zoologist or 

 fisherman would need to be on the lookout for them especially, or 

 they would escape observation. 



Outside the State of New York brook lampreys are reported 

 by Jordan x to be present in the streams of New Jersey, Penn- 

 sylvania, Indiana, Wisconsin and branches of the Ohio river. 

 Creaser and Hubbs 2 report its presence in southern New Eng- 

 land, and as far south as Maryland. 



In the streams of Michigan the zoologists connected with Michi- 

 gan University have found them in abundance near Ann Arbor 

 and have made fundamental studies of their classification, habits 

 and development (Reigharcl, 3 Young and Cole, 4 Okkelberg, 5 ).
