Description. — In habit like Polypedates maculatus. Head mode- 

 rate, with flat forehead, high muzzle, and rather angular canthus ros- 

 tralis ; nostril elliptical, just below the canthus rostralis near the end 

 of snout. Eye large, prominent ; tympanum circular, nearly half the 

 width of eye ; extremities moderate, with rather small disks and 

 well-developed subarticular tubercles. Fingers and toes quite free ; 

 third finger longest, fu\st and foui'th equal, second shortest ; carpus 

 with three blunt tubercles. Toes fringed with a hardly conspicuous 

 cutaneous fold ; fourth toe longest by far, third longer than fifth ; 

 first with a small blunt tubercle at the base. Skin smooth, hinder 

 side of thighs rather granular ; a small fold above the tympanum. 

 Cleft of mouth broad; tongue large, tapering in front, free and 

 deeply forked behind ; palate very narrow ; inner nostrils and eusta- 

 chian tubes moderate. Vomerine teeth in two rather short, widely 

 interrupted oblique series, each beginning near the hinder interior 

 angle of the nostril, and convergent towards behind. In the single 

 male individual in our Collection, neither a vocal sac nor a slit on 

 the side of the tongue is to be found. Above (in spirits) more or 

 less uniform blackish ash, lighter (in two specimens purpUsh red) 

 dotted and marbled ; generally on each shoulder a white spot ; be- 

 neath dull yellowish, throat marbled with brown. Length of body 

 31" ; length of front extremity 2^" ; length of hinder extremity 5^'. 



The skeleton is distinguished by the firmness of its structure, joined 

 with a proportional slenderness of all the parts. Several portions of 

 the skull are not ossified : there is one fonticulus between the parietal 

 and frontal bones, whilst at the same place in Cystignathiis, an ossi- 

 fied part of the capsula cerebri interior forms a large os intercalare, 

 separating widely the parietal bones from the frontals, and the latter 

 from one another. The sides of the cranium exhibit a large ossified 

 plate in the anterior half, but are fibro-cartilaginous in the posterior. 

 The determination of the single bones between the petrosal and max- 

 illary joint is rather difficult, the os tympanicum being separated into a 

 superior and inferior part : the siiperior part emits the processus 

 mastoideiis, curved, but not reaching the upper maxillary bone, and 

 another process directed towards the joint, and united by sutures with
