AMPHIBIA. 

 CAUDATA. 



1. PLETHODON ERYTHRONOTUS (Green). 



The red-backed salamanders were found to be common in decayed 

 tree trunks in the woods. Their preference seemed to be for pine 

 logs, although they were found in tlie decayed trunks of other trees as 

 well as under stones and rubbish. One individual was taken with a 

 partly regenerated tail. 



12 specimens, 56-98 mm., September 26, 1913, U.S.N.M., No. 

 51943-51954. 



2. AMBYSTOMA JEFFERSONIANUM (Green). 



Common in the lowlands near small streams, under logs. 



6 specimens, 54-65 mm., September 26, 1913, Nos. 51937-51942. 



SALIENTIA. 



3. HYLA PICKERINGU Holbrook. 



Although the species is common in the region, judging from the 

 numbers of individuals seen and the calls heard, specimens were 

 difficult to obtain. Several specimens were taken in swampy places 

 near Sunday Lake. 



1 specimen, 17 mm., September 6, 1913, No. 51923. 



2 specimens, 26 and 28 mm.. May 9, 1914, Nos. 51924-51925. 



4. HYLA VERSICOLOR LeConte. 



A specimen of this species was captured on June 6, 1914, but escaped 

 before it could be preserved. 



5. RANA PIPIENS Schreber. 



This species was found to be very abundant about ditches and in 

 swampy places. It is the first of the amphibians to appear in the 

 spring, specimens being taken about the middle of April. Eggs of 

 this species were found on April 19, 1914, and small tadpoles of 

 this species were seen the latter part of the month. 



4 specimens, 40-85 mm., September 6, 1913, Nos. 51927-51930. 



6. RANA CLAMITANS Latreille. 



This species was rather uncommon, although not rare. Several 

 specimens were taken from an old open well in a swamp in the fall, 

 while others were captured in the spring. 



4 specimens, 40-55 mm., September 6, 1913, Nos. 51933-51936.
