Habitat. Northern Queensland and New Guinea. 



The shorter hind Hmbs distinguish this species from R. papua ; 

 in this respect there is complete agreement with R. krefftii, the 

 male of which differs in the presence of external vocal sacs and of 

 a humeral gland. 



104. Rana sw^inhoana.

Vomerine teeth in short oblique series between the choanse or 

 extending beyond the level of their posterior borders, nearer to 

 each other than to the latter.' 



Head as long as broad or slighly broader than long, much 

 depressed; snout rounded, moderately projecting beyond the 

 mouth, as long as the eye ; canthus rostralis obtuse ; loreal region 

 moderatel}' oblique, concave ; nostril equally distant from the eye 

 and the tip of the snout or a little nearer the latter ; distance 

 between the nostrils greater than the interorbital width, which is 

 equal to or a little less than that of the upper eyelid ; tympanum 

 very distinct, half the diameter of the eye, li to 2 times its dis- 

 tance from the latter. 



Fingers moderately long, the tips dilated into moderately 

 large discs with a groove separating the upper from the lower sur- 

 face and measuring half the diameter of the tympanum ; first finger 

 as long as or slightly longer than the second ; subarticular 

 tubercles rather large and very prominent. 



Hind limb long, the tibio-tarsal articulation reaching the tip 

 of the snout or a little beyond, the heels overlapping ; tibia 3| to 

 5 times as long as broad, if to 2 times in length from snout to 

 vent, shorter than the fore limb, a little longer than the foot. 

 Toes with discs similar to those of the fingers, entirely webbed or 

 two phalanges of fourth free; outer metatarsals separated nearly 

 to the base ; subarticular tubercles moderately large and prom- 

 inent ; no tarsal fold ; inner metatarsal tubercle oval, feebly 



I In the larger female from Kosempo, the vomerine teeth present a curious 

 anomaly : they form a single V-shaped group just behind the level of the choanje.
