Spelerpes ruber (Daiidin). — A common species in spring heads. 

 I have taken it in Philadelphia, Chester, and Lancaster Cos., and 

 in Camden Co., N. J. It seems fairly well distributed and has 

 been obtained in the AUeghanies at Round Island, Clinton Co. 

 (Rhoads), and in Blair Co. (Dr. ^McCook); also at Wilmington, 

 Delaware. I fail to distinguish the variety montanus Cope. 



Desmognathus ocrophaea Cope. — This seems to be a boreal 

 species and I have only seen specimens from the higher AUe- 

 ghanies, Harvey's Lake, Luzerne Co. (Stone), Lake Ganoga, 

 Sullivan Co. (Rhoads), and Clinton Co., Pa. (S. Brown). 



Desmognathus fusca (Rafinesque). — Probably our most abun- 

 dant salamander. Found throughout eastern Pennsylvania, 

 northern and southwestern New Jersey, but apparently not in 

 the streams of the pine barrens. In Delaware it occurs in the 

 Brandywine drainage and probably elsewhere. 



Desmognathus nigra (Green). — The only Pennsylvania speci- 

 men that I have seen is one presented to the Academy by Dr. 

 Holbrook without definite locality. 



Diemyctylus viridescens Rafinesque. — An abundant species in 

 the lakes and ponds of the mountainous parts of Pennsylvania 

 and New Jersey; the terrestrial form is common in the hemlock 



I have taken it sparingly in York and Chester Cos., but not 

 about Philadelphia nor in southern New Jersey, though Dr. Wilson 

 obtained some near Newark, Delaware. 



Bufo lentiginosus americanus (Holbrook). — Everywhere abun- 

 dant from the mountains to the coast, including the pine barrens. 



Acris gryllus crepitans Baird. — I have found this species com- 

 mon along the lower Delaware and Susquehanna valleys. H. W. 

 Fowler has secured it at Cape May, N. J., and S. N. Rhoads ob- 

 tained it in Sussex, Somerset, and Warren Cos., in the upper part 

 of^the State. 



Chorophilus triseriatus Wied. — Personally I have not observed 

 this frog but Cope states that it is common in southwestern New 

 Jersey and he also observed it in southern Chester Co., Pa. 

 Rhoads obtained specimens at Pine Grove, Cumberland Co., Pa. 



Hyla versicolor Le Conte.— This is the most frequent tree frog 

 during the summer, for the others are seldom seen except when
