 the choante. Head depressed, much longer than broad ; snout 

 long, pointed ; cauthus I'ostralis obtuse ; loreal region not very 

 oblique, concave; nostril much nearer end of snout than eye; 

 interorbital space as broad as or broader than tlie upper eyelid ; 

 tympanum very distinct, nearly as large as the e\e, or at least | 

 its diameter. Fingers slender, elongate, first not extending beyond 

 second ; foot as long as or nearly as long as the distance between 

 tympanum and vent ; toes very slender, half-webbed ; tips of 

 fingers and toes dilated into very small disks; subarticular tubercles 

 moderate ; a small oval inner and a small rounded outer meta-

 reddish yellow with dark brown markings, forming sliort cross-

 Capt. Flower obtained many specimens near Jenau and Alor Star, 

 Kedah, and Di\ Annandale caught them hopping about in a rice- 

 field near Biserat, Jalor. Capt. Flower found them among 

 swampy paddy-fields, sitting iu the grass on the ridges betweeii 

 the submerged fields, leaping into the wator when alarmed, but 

 always at once swimming back to the land, "liemarkably nimble, 

 active frogs, and specimens 1 had in captivity used to climb up a 

 vertical surface of glass like a true tree frog."'
