186 ON NEW REPTILES AND BATRACHIANS FROM BORNEO. [Mar. 6, 



space as broad as the upper eyelid ; tympanum distinct, one half 

 or two-fifths the diameter of the eye. Fingers free ; toes half- 

 webbed ; disks of fingers a little smaller than the tympanum ; 

 subarticular tubercles moderate ; a small inner metatarsal tubercle. 

 The tibio-tarsal articulation reaches the tip of the snout. Upper 

 parts smooth or with small flat warts ; belly and lower surface of 

 thighs granulate. Grey-brown above, with dark brown sym- 

 metrical markings, a cross-band between the eyes being constant ; 

 usually a )( or )-(-shaped marking on the anterior part of the 

 body ; a dark streak on the cauthus rostralis ; limbs with dark 

 cross-bars ; lower parts white, with or without brown spots on 

 the throat. 



From snout to vent 40 millim. 



I have examined specimens from Mts. Penrissen, Dulit, and 

 Kina Bulu, in Borneo : also from Great Natuna. The species 

 is closely allied to the Javan 1. aurifasciatus, to which the first 

 Bornean specimens were referred by the late Prof. Peters ('Ann. 

 Mus. Genova, iii. 1872, p. 44). 7. aurifasciatus has a smaller, 

 less distinct tympanum, shorter digits, and a brighter coloration, 

 beiug marked with reddish, dark brown, green, and bright yellow. 



Calophrynus heterochirus. (Plate XVII. fig. 4.) 



Tongue large, pyriform, covering the floor of the mouth. Snout 

 very short, slightly prominent, truncate ; canthus rostralis strong ; 

 loreal region nearly vertical ; interorbital space broader than the 

 upper eyelid ; tympanum feebly distinct, measuring about two- 

 thirds the diameter of the eye. First and second fingers very 

 short, not half the length of the third, fourth shorter still, 

 almost reduced to a knob ; toes short, one-third webbed, fifth 

 shorter than third ; tips of fingers and toes bluntly pointed ; sub- 

 articular tubercles feebly prominent ; two feebly prominent 

 metatarsal tubercles. The tibio-tarsal articulation reaches the 

 eye. Skin smooth. Uniform purplish brown above, yellowish 

 white beneath and on the sides of the head ; a few large round 

 yellowish-white spots on the lumbar region and on the back of 

 the thighs. 



A female, full of large-sized ripe ova, measures only 27 millim. 

 from snout to vent. 



Borneo (no precise locality). Type in the Sarawak Museum.
