SOME NEW AMPHIBIA SALIENTIA. 

 BY THOMAS BARBOUR. 



Among material selected from the stock of Mr. Owston, in 

 Yokohama, was the remarkable new frog described below. Un- 

 fortunately it bears no very definite data. The other two new 

 forms were both taken by the author, while on a collecting trip 

 in 1906-'07. 



Rana subaspera sp. nov. 



This specimen was sent to Dr. Stejneger for examination. His letter, 

 confirming the surmise that it was undescrihed, says: "It is * * * 

 l>r< ihably nearest related to Rana feae, and also to Rana Uebigii and Rana 

 boulengeri." He then calls attention to the enormously developed first 

 metacarpal, "somewhat recalling that of R. holsti, with which species, 

 however, the present one has nothing to do." He adds: "The large 

 gland above the axil is also very remarkable." 



Descrijition. — Vomerine teeth in two small oblique groups, situated 

 very slightly behind the choanae. The distance between these is a little 

 less than their distance from the choanae. Habit rather stout. Head 

 much broader than long; snout very short, well rounded; no canthus 

 rostralis; nostril much nearer tip of snout than eye; interorbital space 

 narrower than upper eyelid; tympanum distinct, three-fourths the diam- 

 eter of the eye. Fingers moderate, first much longer than second ; first 

 metacarpal very greatly developed (similar to R. holsti); toes rather long, 

 entirely webbed; subarticular tubercles well developed; tips of fingers 

 and toes slightly dilated; inner metatarsal tubercle narrow and elongate, 

 two-thirds the length of the inner toe; outer metatarsal tubercle indis- 

 tinct; no inner tarsal fold. The tibiotarsal articulation reaches the eye; 

 tibia one-half the length of the body. 



Body warty, all upper parts and sides of body and limbs with many 

 round, prominent warts. No fold from eye to shoulder as in R. feae. A 

 large kidney-shaped gland above each axil. Uniform olive brown on all 

 upper surfaces and sides; tympanum lighter; under surfaces chestnut 

 brown with olive marblings. Male without internal vocal sacs. The type, 

 a male, evidently taken in the breeding season, has light-colored spine-
