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
