snout than the eye; the distance between the nostrils equal to or 

 greater than the interorbital width, which is nearly equal to or 

 less than that of the upper eyehd; tympanum very distinct, 

 f to f the diameter of the eye, f to i| times its distance from the 

 latter. 



Fingers moderate, the tips swollen or dilated into very small 

 discs, first longer than the second, third as long as or a little longer 

 than the snout; subarticular tubercles moderate, moderately pro- 

 minent. 



The tibio-tarsal articulation reaches the eye or between the 

 eye and the tip of the snout ; heels overlapping when the limbs 

 aire folded at right angles to the body ; tibia 3 to 3^ times as long 

 as broad, nearly 2 to 2\ times in length from snout to vent, 

 shorter than the fore limb, as long as or a little longer or a 

 little shorter than the foot. Toes moderately long, the tips dilated 

 into very small discs, entirely or nearly entirely webbed ; subarticu- 

 lar tubercles rather small, moderately prominent; a short and 

 feeble tarsal fold, sometimes absent; inner metatarsal tubercle 

 moderately prominent, narrow, I to ^ the length of the inner toe ; 

 no outer tubercle. 



Upper parts smooth or with small warts or interrupted longi- 

 tudinal folds ; upper eyelids tubercular ; sometimes a transverse 

 fold behind the eyes ; a glandular fold from the eye to the shoulder. 

 Lower parts smooth. 



Brown, grey- brown, or dark olive above, with or without 

 rather indistinct darker spots ; sometimes two Hghter strips on the 

 back and the canthi rostrales, meeting on the tip of the snout; 

 sometimes a light vertebral stripe ; a dark cross-band between the 

 eyes often present ; a black spot sometimes present on the tympa- 

 num ; upper lip with dark vertical bars, two below the eye; limbs 

 with dark cross-bands ; hinder side of thighs dark brown, with 

 light spots or marblings. Lower parts white, uniform or speckled 

 or spotted with brown. 



Males with internal vocal sacs ; the head rather larger than 

 in females. 



Osteological characters as in R. macrodon. 



Eggs rather large, 2^ millim. in diameter in female measur- 

 ing 58 millim. from snout to vent. 



Habitat. Celebes, Talaut Ids., Nusa Laut and Saleyer. 



Closely allied to R. macrodon, but much smaller, vomerine 

 teeth in shorter series, and males with vocal sacs. Although the 

 latter character justifies its specific separation, it is not easy to 

 distinguish it from young specimens of R. macrodon of the same 

 size. 



14. Rana microtympanum. 



Rana microtympanum, Van Kampen, in M. Weber, Zool. Ergebn. IV, 

 p. 386 (1907). 



Vomerine teeth in short, oblique series just behind the level 

 of the choanae. Lower jaw with short, obtuse, tooth-like processes 

 in front.
