space as broad as the upper eyelid ; tympanum i; the diameter of 

 the eye, close to it. 



Fingers moderatel}' long, the tips feebly dilated, without dis- 

 tinct discs, first longer than the second. 



Hind limb long and slender, tibio-tarsal articulation reaching 

 beyond the tip of the snout ; tibia f the length of head and bod}''. 

 Toes nearl}' entirely webbed, the tips dilated into small but distinct 

 discs ; subarticular tubercles prominent ; no tarsal fold ; inner 

 metatarsal tubercle oval, prominent ; a smaller, oval outer tubercle. 



Skin of upper parts smooth or rather rough ; a very narrow 

 dorso-lateral fold. Lower parts smooth. 



Uniform olive above ; a rather broad brown streak below 

 the canthus rostralis ; a large brown temporal spot; limbs with 

 brown cross-bands ; hinder side of thighs with large black spots in 

 a white network. Lower parts uniform yellowish white. 



From snout to vent 48 millim. 



Habitat. Iliwaki Island, Sunda Islands. 



This species has been compared with R. florensis and R. varians 

 but it appears to me, judging from the description, to be more 

 nearly allied to R. gnentheri and R. gracilis. 



71. Rana sautcri. 



Rana saiiteri, Bouleng. Ann. and Mag. N.H. (8) IV, 1909, p. 493. 



Vomerine teeth in strong oblique series originating between 

 the choanse and extending considerably beyond the level of their 

 posterior borders. 



Head as long as broad, much depressed ; snout rounded, feebly 

 projecting be^^ond the mouth, as long as the eye; canthus rostralis 

 obtuse ; loreal region not very oblique, slightly concave ; nostril 

 a little nearer the tip of the snout than the eye ; distance between 

 the nostrils greater than the interorbital width, which is a little 

 less than that of the upper eyelid ; tympanum very distinct, | to f 

 the diameter of the eye, and 2 to 4 times its distance from the 

 latter. 



Fingers rather slender, with distinctly swollen tips, first as 

 long as the second, third longer than the snout ; subarticular tu- 

 bercles strong, very prominent. 



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

 the snout or a little beyond, the heels strongly overlapping when 

 the limbs are folded at right angles to the body ; tibia 4|- to 5|- 

 times as long as broad, i| to i^ times in length from snout to vent, 

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

 Toes slender, the tips dilated into small discs with a groove 

 separating the upper from the lower surface, | webbed, the web ex- 

 tending to the discs of the fourth and fifth, leaving 2 phalanges of 

 fourth free, and separating the outer metatarsals almost to the 

 base ; subarticular tubercles large and prominent ; no tarsal fold ; 

 inner metatarsal tubercle oval, very prominent, :', to | the length 

 of the inner toe ; a small round outer tubercle.
