306 Lake Maxinkuckee, Physical and Biological Survey 



LIST OF SPECIES OF FISHES 



In the following annotated list we use the nomenclature and 

 sequence of species of Jordan and Evermann's Fishes of North 

 and Middle America. 



1. WESTERN BROOK LAMPREY 



LAMPETRA AEPYPTERA (Abbott) 



No lampreys have been seen by us in Lake Maxinkuckee itself 

 and it is possible that they do not occur there. A few catfishes 

 were found dead along the east side of the lake in the spring of 

 1901, and from marks on their sides it was thought that they might 

 have been killed by lampreys, but this is by no means certain. 



Young lampreys, however, are not rare in the Outlet of the lake 

 and in some of the smaller lakes of the region. Fishermen about 

 the lake who go seining for minnows in the Outlet and other 

 streams and waters of the region report the capture of "young 

 eels." 



On June 18, 1901, one of the fishermen living near the lake 

 reported that he had two young eels, obtained while seining for 

 minnows in an old outlet of a drained mud pond. He said that 

 when the lake was drained it was quite full of young eels, and that 

 he could get many more where the two had been caught. The 

 supposed eels were found to be lampreys. In 1906, a fisherman 

 reported finding "young eels" in the Outlet, but none was seen 

 by us at that time. 



On October 7, 1907, a trip was taken with men going to seine 

 for minnows at a point in Outlet Creek, about 3 miles below the 

 lake. The net was dragged through a hole with a muddy bottom, 

 and upon being drawn ashore was found to contain a large amount 

 of mud in which were several lampreys. A few more were taken in 

 a subsequent haul, the total number taken in 4 hauls being 14. 



None of the specimens seen was adult; the largest obtained 

 were the two secured in June, 1901, one of which was 132 mm., 

 and the other 124 mm. in length. This is less than half the length 

 given for the adult, which is given as 12 inches (304.8 mm.). Of 

 the 14 specimens secured in the fall of 1907, the largest was 116 

 mm. and the smallest only 29 mm. long. 



An interesting characteristic of this species is the size it at- 

 tains while still in an immature condition ; none of the specimens 

 obtained has either teeth or eyes developed, while considerably 

 smaller examples of the related /. castanens, with which it was 

 compared, have teeth and eyes well formed. Lampetra ivilderi
