Rana pipiens brachycephala (Cope). 



The western form of the green frog evidently reaches its western 

 limit in Nevada, and from the fact that the expedition only brought 

 home one specimen it may probably be concluded that it is rare in that 

 region. This specimen was collected in Pahranagat Valley, Nevada, 

 May 25, 1891, by Yeruon Bailey (No. 18927). 



As to the name Rana pipiens Schreber, adopted in preference to R. 

 virescens 'Kalm,' 1 may remark that as the latter was never used by 

 Kalni in a binominal sense, it being only the first word of his diagnosis 

 of the species, the former is beyond doubt the oldest tenable name for 

 the species. From some of the recent synonymies it might be inferred 

 that Rana virginiana of Laurenti (1768) would be the name, but I need 

 only quote his diagnosis, viz, "corpore cinereo, dorso quinqueangulato 

 quinquestriato ; maculis rubris; abdomine, pedibusque flavescentibus," 

 to show that it can never be identified as our shad-frog. 



This question has already been settled by Prof. S. Garman in 1888 

 (Bull. Ess. Inst., xx, pp. 90, 100), and I am only induced to repeat and cor- 

 roborate it here, as one might be led to believe, from Cope's treatment 

 of the matter (Man. N. Am. Batr., 1889, p. 399), that Garman is respon- 

 sible for the adoption of Rana virescens.
