Class Amphibia.* 



Family Bufonidce. 



Bufo americanus Le Conte. Toads were scarce here in the 

 breeding season, the only time that adult toads take to water. 

 Some were noticed in spring 1919, but none whatever caught 

 until May, 1920, when a few were observed and one caught, 

 near shore, in the large northwest arm of the large pond. Two 

 others, subsequently captured, were in similar locations. Toads 

 were reported to have been very common about the pond 

 years ago. 



Family Ranidce. 



Frogs were relatively few in Mirror Lake during the time of 

 this survey, though they also had been much commoner at one 

 time. Very few places along the shoreline offered suitable places 

 of seclusion such as they frequent when out of water. 



Rana pipiens Shreber. The common leopard frog could 

 probably not be rated as common here. Numbers were observed 

 in the spring of 1919, but none caught. In fact not until May, 

 1920, when some more were seen, were two caught and iden- 

 tified. They were taken along the edge of the small pond near 

 station 3, and during a few days, half a dozen more were 

 observed along that pond edge jumping from the grass into the 

 water. One was also observed along the south shore of the 

 large pond and one in the northwest arm of that pond near 

 the bridge. 



Rana clamitans Latreille. A large specimen of a male green 

 frog was caught May 15, 1920, while it was squatting at the 

 water's edge on a depressed grassy area, along the southeast 

 shore of the large pond. This species was no doubt scarce. 



Class Reptilia. 



Reptiles were scarce in Mirror Lake. Possibly some other 

 form than the two noticed, was present for somewhat as in the 

 case of Amphibia, their habits of seclusion would make them 

 inconspicuous. 



* Amphibia, since not closely connected with definite stations, are omitted 

 from the Taljle.
