III.— On a Collection of Reptiles and Am- 

 phibians from Mt. Murud, Borneo. By 



Malcolm A. Smith, f.z.s. 



(WitJi one j^late.) 



The collection of reptiles and amphibians made by Dr. 

 Mjoberg is a valuable contribution to the mountain fauna of 

 Borneo. Although only 14 species were obtained, no less than 

 five of them appear new to science. All were caught at high 

 altitudes — between 5500 and 7000 feet. 



The discovery of a new lizard allied to Phoxophrys is of 

 particular note, whilst an interesting adaptation to environ- 

 ment was met with in respect to the breeding habits of a new 

 tree-frog of the genus PhUautus. I am also, thanks to a large 

 series of specimens, able to give the true status of the frog 

 originally described by Boulenger as Mierohyla leucostigma. 



The types of the new species here described have been 

 presented by the Sarawak Museum to the British Museum. 



SNAKES. 



1. Natrix murudensis sp. nov. 



Type female, author's number 7210 collected at 5500 — 

 6000 feet altitude. 



Description of the type. Maxillary teeth 23, the last 2 

 abruptly enlarged. Eye moderate. Eostral broader than 

 high, just visible above ; internasals as long as the praefron- 

 tals, broadly truncate anteriorly ; frontal nearly as broad as 

 long, as long as its distance from the rostral, much shorter 

 than the parietals ; nostril in a partly divided nasal ; loreal 

 longer than high ; 1 prae- and 3 postoculars ; temporals 1 + 2 ; 

 9 supralabials, fourth to sixth touching the eye ; 11 lower 

 labials, 6 in contact with the anterior chin-shields, which are 

 a little longer than the posterior.
