Rana fisheri, sp. nov. (Plato ill, figs. 5a-c.) 



Diagnosis. — Heel of extended hind limb reaching anterior eye canthus, 

 falling considerably short of tip of snout; vomerine teeth between and 

 projecting posteriorly beyond choanse; no black ear patch; vertical 

 diameter of tympanic disc greater than distance between nostrils and 

 eye; hind feet webbed for about two-thirds; one small metatarsal 

 tubercle; one weak dorso-lateral dermal fold, no dorsal folds between; 

 posterior lower aspect of femur granular; back and sides with numer- 

 ous small, distinct, dark spots, surrounded by lighter; no external vocal 

 sacs. 



Habitat. — Vegas Valley, Nevada. 



Type.—U. S. Nat. Mus.,No. 18957; Vegas Valley, Nevada, March 13, 

 1891 ; V. Bailey coll. 



Not closely allied to any of the known species. The coloration is 

 very distinct, resembling somewhat that of R. aesopus; the great 

 size of the tympanic disc is also quite characteristic, being larger than 

 in any of our species, except R. catesbiana, elamitans, and septentrionalis. 



I should have considered it rather risky to describe a new species of 

 Rana from the West had it not been for the fact that the great number 

 of the specimens collected established beyond a doubt the constancy 

 of the characters mentioned. 



This species is dedicated to Dr. A. K. Fisher in recognition of his 

 share in the herpetological success of the Death Valley Expedition. 



[Frogs were tolerably common in Beaverdam Creek near its junction 

 with the Virgin in northwestern Arizona, May 8, but whether Rana 

 fisheri or R. pipiens brachyeephala is not certain. The former was col- 

 lected in Vegas Valley (type locality); the latter in Pahranagat 

 Valley.— 0. H. M.]
