same corner of the other eye much greater than the intertympanic width in 

 R. grylio, somewhat greater in R. clamitans, about equal in R. catesheiana 

 and equal in R. heckscheri, i.e., in the males. 



In the field at night we mistook the first one for a green frog until another 

 specimen called, but in our original description we called it a new bullfrog. 

 More material and more life history clues are needed to establish its place 

 in the Rana catesheiana- Rana clamitans series.

Supplementary records. Miss Dickerson relying on Cope says "It is re- 

 ported from the Adirondack Mountains, from Lucknow, Ontario, and Fort 

 Ripley, Minnesota, and from Moose River and the Hudson Bay region. 

 Strictly speaking, Madrid and Garrison's Creek, N. Y., are not Adirondacks 

 proper but Paulmier found one on Black Lake in the Fulton Chain. On June 

 13 and 14 A. H. and A. A. Wright found the species from White Lake to Old 

 Forge, N. Y. On June 28, Messrs. S. C. Bishop, C. K. Sibley, C. R. Crosby, 

 M. D. Leonard, P. W. Claassen and L. West found it at Hart or Clear Lake 

 (Mt. Marcy region). On July 7, Mr. C. W. Leister also recorded it there as 

 did Mr. and Mrs G. B. Upton from July 7-12. On July 13-15 Dr. S. C. 

 Bishop studied it in this place. Mr. C. W. Leister has also seen it in Connery 

 Pond, about four miles northeast of Lake Placid. G. A. Boulenger (1920, p. 

 424) in his range Southern Canada and New York to Montana and Utah 

 omits Pope's records 1914-1918 from Maine, yet No. 8 in his measurements 

 from Eustis, Maine, must be a Pope specimen. With Pope's discoveries of 

 this species in Frankhn County, Me., with the general distribution of this 

 species in the Adirondacks, search at the right time ought to reveal the species 

 in New Hampshire, Vermont and possibly in the Catskill Mts., N. Y. and 

 doubtless in some of the swamp area around Oswego, N. Y., or north of 

 Auburn, N. Y. Nash, (p. 10) holds that it extends in Ontario from "Bruce 

 County and northward and westward, not common." He doubtless is
