Rana virgatipes Cope. 

 Sphagnum Frog. 



The clack, clack, clack, clack, clack of this frog could be heard 

 about the Rancocas Creek above New Lisbon, in Burlington 

 county, on May 12th, 1907. It occurred at intervals, interrupt- 

 ing the stillness of a backward spring. Though loud and not 

 often uttered, in comparison with those found at Mare Run, their 

 croaking could be heard at quite a distance. Sometimes the ani- 

 mals must have been quite close, for we could hear them when 

 but a few feet away without seeing them. It may have been that 

 the weather was too cold, for their croaking was always located 

 as coming- from among the submerged and overgrown vegetation 

 along the banks. In such places the temperature was considerably 

 higher by mid-day than elsewhere. When Mr. Hunt visited this 

 place just a year previously, the frogs were very numerous. The 

 weather at that time, however, though about the same time in 

 May, was much warmer. In the evening, during the night, and 

 in the early morning, they were very noisy, but during the day 

 were more or less quiet, only an occasional croak being heard at 

 intervals, or as noted above. We found a lot of spawn, though 

 were unable to identify it as belonging to this species. It re- 

 sembled that found in Mare Run, in similar situations, as it was 

 formed in strings and wound about the numerous aquatic plants 

 in still water. These strings were quite long and very abundant. 

 Attempts at their transportation and hatching failed. 



Rana catesbeiana Shaw. 

 Bull Frog. 



Found at Green Creek on June 9th, 1907. 



Mr. S. H. Hamilton found it at Woodport in Lake Hopatcong, 

 Hurdtown and Mount Hope in Morris county, and in the pond at 

 Oxford Furnace, in Warren county. On one occasion large ex- 

 amples were found crawling through briars and thick vegetation, 

 evidently in an attempt to scrape off a number of leeches which
