March, 1921] Macro-Fauna of Mirror Lake 175 



Since none of the fishes could be ascribed to any particular 

 stations, they are entirely omitted from the table. 



Family Siluridce. 



Ameiurus nebulosus (Le Sueur). The common bull-head 

 or brown bull-head was rare in Mirror Lake. Only one spec- 

 imen was taken, but it must be noted that since they are 

 bottom dwelling forms, and since the seining along the bottom 

 was very much interfered with by projecting stumps, branches, 

 and stones, others may have escaped. 



Ameiurus melas (Rafinesque). The black bull-head was 

 possibly a little less scarce, if the fact that three specimens were 

 taken in the seine as compared with one of the above, is basis 

 for this judgment. 



Family CatostomidcE. 



Catostomus commersonii (Lacepede). The common sucker 

 was also apparenth^ rare. One specimen was secured. 



Family CyprinidcE. 



Cyprinis carpio Linn. This introduced form, the well known 

 carp was not secured in the seine, but is here included on the 

 basis of positive declaration that it has been taken from the 

 pond, on the fact that we caught glimpses of what unmis- 

 takably were carp, and also on the fact that a peculiar spec- 

 imen was caught which proved to be a true hybrid between a 

 carp and a goldfish. 



Carassius auratus (Linn). The goldfish is a common, con- 

 spicuous form in the pond, but it certainly did not rank better 

 than third in abundance, although it was the fish most readily 

 seen. 



Pimephales notatus (Rafinesque). The blunt-nosed minnow 

 was common but probably somewhat less so than the goldfish. 



Abramis crysoleucas (Mitchill). The golden shiner was the 

 most abundant of all fishes in Mirror Lake. Seining disclosed 

 great numbers, quite in excess of the second most numerous 

 species. 



Family CentrarchidcE. 



Apomotis cyanellus (Rafinesque). The green sunfish was 

 also common, in fact very likely the second in abundance of 

 all the fishes.
