First report on the economic features of the amphibians of Pennsylvania, 

 H. A. Surface (Bi-J/o, Zool. Bui. Penn. Dept. Agr., 3 (1913), No. 3-4, pp. 67- 

 152, pis. 10, figs. 25). — This paper deals with the mud puppy, salamanders, 

 toads, and frogs known to occur in Pennsylvania, their habits, hibernation, 

 reproduction, enemies, food, and economy. The author takes up the collecting 

 and iireserving of specimens, the classification, gives a key to the orders of 

 Pennsylvania Amphibia, and a color key to the salamanders of the State, 

 reports upon the stomach contents of Pennsylvania amphibians and popular 

 errors concerning them, and defines the terms used. A bibliography of 19 titles 

 and an index are included. 



The investigations show that none of the amphibians of Pennsylvania are 

 injurious or harmful in any way but that on the other hand they are often very 

 useful destroyers of insect pests, snails, and slugs, and some are valuable be- 

 cause of their edible flesh. Others are of value as bait for fish and as food for 

 fish and birds.
