AN ANNOTATED LIST OF THE COLD-BLOODED 



VERTEBRATES OF DELAWARE COUNTY, 



PENNSYLVANIA. 



BY HENRY W. FOWLER. 



While studying the various local collections of fishes, 

 amphibians and reptiles in the Academy of Natural Sciences 

 of Philadelphia, I found considerable material representative 

 of this section. As many of the localities have not been 

 given before, and are of value in studies of geographical dis- 

 tribution, I prepared the present paper as a slight contribution 

 to science. It is believed that the list is fairly representative, 

 though inevitably a number of other forms will be added with 

 future studies and collecting. Several scattered records are 

 given for species likely to be overlooked. Among the species 

 included as most likely to be discovered within the county 

 limits, and which occur in adjacent or contiguous districts, 

 are: — Acipenser brevirostrum , Lepisosteus osseus, Schilbeodes 

 insigyiis, Carphophiops amcenus and Regina leberis^^ The only 

 complete paper dealing with a portion of the present subject 

 is the interesting account of the tailless amphibians, published 

 in these Proceedings, in 1908, by Mr. T. Chalkley Palmer. 



*I am later informed that the Museum of the Institute contains one 

 of. the last named species, taken from a water hole in a quarry on Ridley 

 Creek near Fox's Bridge, below Moylan, Pa.
