 of the eye. Mouth broader than long. Limbs moderately deve- 

 loped ; first finger longer than the second, and as long as the fourth. 

 Tlie length of the body equals the distance between the vent and 

 the metatarsal tubercle. Toes nearly half webbed ; metatarsus

 upper parts with a few small scattered tubercles and some short oblique 

 glandular folds. The length of the body is somewhat less than the dis- 

 tance between vent and heel. No fold of the skin along the tarsus ; 

 metatarsus with a single tubercle ; the interdigital web extends to the 

 outer phalanx of the third and fifth toes ; disks of the fingers and toes

 the median hue of the back, to the vent. 



A single specimen has been received from Ceylon ; it is 18 millims. 

 long, the hind limb being 23 millims. In spite of its diminutive size, 

 the specimen, which is a male, appears to be adult. 



IxALus opiSTHORHODUS. (Plate XXXVII. fig. 3.) 



Snout longer than the eye, rather pointed in front, with angular 

 canthus rostralis. Tympanum hidden by the skin. Skin of the 

 upper parts smooth, with a few short oblique glandular folds. The 

 length of the body is a little more than the distance between the
