Through the kindness of Mr. Arthur H. Norton, 

 T am permitted to publish the following data collected 

 by him: 



"Rana septentrionalis. — It was observed in Van 

 Buren and Caswell, Aug. 15-16, 1914. It was found 

 to be numerous in two small dead water ponds in 

 Caswell, locally called Mud and Girard Ponds. They 

 were more conspicuous than Rana clamata, inhabiting 

 similar places, i.e., tussocks of sedge on the edges and 

 the beds of lily pads near shore. 



"At Van Buren they were found in ditches by the 

 railroad track and were common. 



"At Mud Pond, Caswell, they were heard calling, 

 and the same is true of R. clamata. 



"The call of R. septentrionalis was found to be 

 similar in nature to that of R. clamata, but differed 

 strikingly in tone, being higher and slightly metallic, 

 resembling closely the sound produced by striking a 

 ]on# nail on the head with a hammer in driving it 

 into heavy timber. I did not observe the pungent 

 odor which has given it the name of Mink Frog." 



From these facts I conclude that Rana septentri- 

 onalis is rather generally distributed in the northern 

 part of Maine, and that it is found in the same locali- 

 ties as R. catesbiana and R. clamata, not tending to 

 replace either of these species.

SOME AMPHIBIANS AND REPTILES OF 

 DELAWARE COUNTY, PENNSYLVANIA 



The following list includes species I have seen 

 or collected within the county limits since the fall of 

 1912. Where the number of specimens is given, the 

 error is on the side of understatement, as in many 

 cases I have not recorded in my notes specimens seen 

 which were not caught. 



Plethodon erythronotus (Green). — Both forms 

 common in Cobb's creek near Haverford and at Darby 

 creek near Coopertown Road. 



Spelerpes bislineatus (Green). — Common in 

 Cobb's creek near Haverford, and in a small creek
