others it can be made out only by close scrutiny. The back of some, as well 

 as the sides and thighs, are covered with large round tubercles, while in one the 

 back has only scattered spine-bearing warts. In some the second finger is con- 

 siderably longer than the first while in others they are of about equal size. In 

 one the parotid gland has a tendency toward a crescentic shape, while in another 

 it is simply elongate. The amount of black both above and below varies 

 extremely.

Two specimens agree perfectly with the description of this subspecies, 

 except that there is a web between the outer fingers. Unfortunately the locality 

 tags are missing, and it is impossible to state whether they came from about 

 Ichang or from Szechwan. Stejneger has covered the question of the identity 

 of the various east Asiastic tree toads so completely that there is no need of 

 further remarks on the subject. The Chinese and Japanese specimens in the 

 M. C. Z. collection substantiate his conclusions. 



HYLA MONTICOLA, sp. nov. 



Plate 1, Fig. 2. 



Type: No. 2553 M. C. Z. Washan, western Szechwan, China. Altitude 

 10,500 feet. One adult specimen. W. R. Zappey. 



Very distinct from Hyla annectans Boulenger and Hyla chinensis Gunther 

 with specimens of which it has been compared. 



Vomerine teeth in two elongate series, well separated, converging back- 

 ward, beginning between the middle of the extremely small choanae and extend- 

 ing considerably posterior to them. Tongue large and long, deeply nicked 

 behind. Nostrils midway between eye and tip of snout, their distance from 

 each other much greater than their distance from the labial margin. Inter- 

 orbital space much greater than width of upper eyelid. Tympanum almost 

 circular, its diameter less than half that of eye. Fingers distinctly webbed at 

 base, slender, terminating in very small disks. Feet with rather slightly devel- 

 oped webs, tarsometatarsal joint, reaching tip of snout. Toes long, disks
