distance being niiicli greater tlian their distance from the eye or than 

 the interorbital space, which is narrower than upper eyehd; vertical 

 diameter of tympanum greater than horizontal, a trifle more than one- 

 half the diameter of eye, and more than twice the distance of tym- 

 panum from eye; first finger slightly extending beyond second ; webs 

 of toes deeply excised, barely reaching the middle of basal phalanx of 

 fourth toe; inner metatarsal tubercle oval, projecting, slightly shorter 

 than its distance from subarticular tubercle of first toe; a strong 

 conical outer metatarsal tubercle; subarticular tubercles stronglj^ 

 developed; tibio-tarsal articulation of extended hind leg reaches 

 almost to the nostril; tibia one-lialf the total length; heels overlap- 

 ping by the width of the interorbital space; skin above with numer- 

 ous small scattered granules, those on the sides larger; dorso-lateral 

 glandular folds very narrow and sharply defined, their shortest dis- 

 tance being contained about five times in the total lengtli; lower 

 surface smooth except the proximal half of the posterior aspect of the 

 femur which is granular. Color (in alchol) above uniform pale drab, 

 with a few minute dusky spots on the back; the brown stripe from 

 tip of snout to eye, very narrow, and tlie tympanic dark patch rather 

 pale and ill-defined between eye and tympanum; humeral stripe 

 and crossbars on limbs obscure; underside uniform whitish.

ThemcrZf(U.S.N.M. No. 17520; Tsushima; May, 1885; P. L. Jouy, 

 collector) is smaller (total length 37 mm.), with relatively longer tibia 

 (20 mm.). The snout is somewhat shorter^ with the nostrils nearer 

 to the tip than to the eye; tym})anum slightly larger and nearer the 

 eye; first finger has the swollen pad set with asperities, character- 

 istic of the breeding male; webs less excised, reaching to the anterior 

 third of the basal phalanx of fourth toe; outer metatarsal tid)ercle 

 barely indicated; tibio-tarsal articidation reaching tip of snout, over- 

 lapping by more than interorbital space; shortest distance between 

 dorso-lateral folds one-sixth the total length; lower ])ack and sides 

 with numerous small, white-tipped, pointed tubercles, and in addition 

 on sides large glandular warts. Color like the female, but canthal 

 stripe and ear-patch darker and better defined; underside densely 

 sprinkled w^ith minute brown dots. 



Remarks. — Most of the dilTerences between the two specimens as 

 pointed out here are sexual, the relative shorter body, the pad on the 

 first finger, the greater extent of the webs indicating the male. The
