fifth toes. Disks well developed. The length of the body 

 equals the distance between the vent and distal end of meta- 

 tarsus. Upper parts dark violet (in spirits), with numerous 

 round, smaller and larger, bright yellow spots. Hinder side 

 of the thighs marbled with brown. Lower parts dirty yellow, 

 throat marbled with brown. 



One specimen is 34 millims. long, the hind limb being 

 48 millims. 



Ixalus oxyrhynclius. 



Snout rather elongate, sharply pointed, projecting beyond 

 the mouth ; loreal region flat, vertical ; canthus rostralis an- 

 gular. Eye of moderate size ; tympanum distinct, one-third 

 the size of the eye. Upper parts smooth, with a pair of folds 

 commencing from the eyelid, and converging towards the 

 middle of the back. Throat smooth, not granular. Meta- 

 tarsus without fold, with a single tubercle. Fingers not 

 webbed ; the interdigital web of the hind foot does not reach 

 the last phalanx of the third and fifth toes. Disks small. 

 The length of the body is rather less than the distance be- 

 tween the vent and heel. Upper parts reddish olive, with a 

 large, hourglass-shaped brown blotch on the back ; its ante- 

 rior base is between the orbits, and laterally it is bordered by 

 the convergent folds of the skin. Limbs with a few blackish 

 bars ; an almost black spot occupies the hand and its root. 

 Loreal region and a tympanic spot, the vent and hind parts 

 of the thighs, and the lower part of the foot black. Lower 

 parts white, throat dotted Avith brown. 



Two specimens, the larger of which is 24 millims. long, the 

 hind limb being 42 millims. 



Ixalus jjulchellus. 



Snout depressed, obtuse, but rather longer than the eye, 

 without canthus rostralis. Tympanum covered by the skin. 

 Skin smooth ; abdominal surface coarsely granular, the gra- 

 nules extending over a part of the throat. The length of the 

 body is a little more than the distance between vent and heel. 

 No fold along the tarsus ; metatarsus with a small tubercle. 

 Interdigital web rather broad, extending nearly to the ulti- 

 mate phalanx of the third and fifth toes. The two outer 

 fingers united by a membrane for a considerable part of their 

 length. Disks well developed. Upper parts yellow (in spi- 

 rits), mottled with violet, and with scattered minute black 

 dots ; upper arm, anterior and posterior sides of the femur 

 colourless ; lower parts uniform white. 



One specimen is 23 millims. long, the hind limb being 

 38 millims.
