VII. TWO NEW BATRACHIANS AND A NEW SNAKE 



FROM BORNEO AND THE MALAY PENINSULA. 



By Malcolm A. Smith, F.Z.S. 



(Plate n.) 



I am indebted to the Director of the Federated Malay 

 States Museums, for the opportunity of examining two 

 separate collections of reptiles and hatrachians. One of 

 them was made by the native Museum collectors in 1919, 

 upon Mt. Dulil, Sarawak, Borneo ; the other, also in the 

 same year, during the expedition of Messrs. Robinson and 

 Kloss to Peninsular Siam. Amongst a large amount 

 of interesting material tlie following species appear to be 

 new : — 



Rana pullus, sp. nov. (pi. 11, fig. 1). 



Vomerine teeth in two very oblique series, commencing 

 between the choanae and extending well behind, the distance 

 between them less than their distance from the choanae ; 

 tongue without median papilla ; head as long as broad, 

 snout rounded or obtusely pointed, feebly projecting beyond 

 the mouth, a little longer than the eye ; canthus rostralis 

 (jbtuse, loreal region obli(|ue, concave ; nostril nearer the 

 tip of the snout than the e>e ; distance between the nostrils 

 e((ual to or greater than thai of the upper eyelid ; tympanum 

 very distinct, 1/2 to W/Tt the diameter of the eye. 



Fingers moderately long, first slightly shorter than 

 second ; tips with moderately large discs, which are a little 

 broader than long, and with a groove in front separating 

 the upper from the lower surface ; subarticular tubercles 

 large and prominent ; discs of the toes like those of the 

 fingers ; toes half webbed, the web reaching the disc of the 

 fifth toe and penetrating to a ([uarter between the outer 

 metatarsals ; subarticular tubercles moderately prominent ; 

 a tarsal fold ; inner metatarsal tubercle feebly prominent, 

 '^/A to 4/5 the length of (he inner toe ; no outer tubercle ; 

 tibia 2 to 2V4 times in (hslance from snout to vent, as long 

 as or a little longer than Ihe fool ; the heels meet when the 

 limbs are folded at right angles to the body ; the tibiotarsal 

 articulation reaches the snout or not quite so far. 



Skin witli a glandular network of fine folds, the reticu- 

 lations largest and best marked al)ove.* A strong glandular 

 fold irom the eye to the shoulder. 



Dark grey or blackish above, whitish below, thickly 

 speckled, except on the belly, with, dark grey. Some of the 

 young have light and dark bars on tlie hind limbs. 



* The skin of tliis frog is unusually tender. There is not a 

 single example in the serius in which the skin is not torn or 

 damaged in some part of Ihe hody. The glandular reticulations 

 leferred to are possibly not so prominent in life as in spirit 

 specimens.
