344 On the Herpetological Fauna of Mount Kina Baloo. 



small, with round pupil ; nostril valvular, an oblique slit 

 between two nasals ; three pairs of chin-shields. _ Body cylin- 

 drical, elongate ; scales smooth, without apical pits, in tifteen 

 or seventeen rows. Tail moderate j subcaudals in two rows. 



The affinities of this genus are with Ojoisthotropis, not with 

 Ablabes. 



Two species from Borneo : — 



Scales in 17 rows ; ventrals 190-200 ; two 

 prefrontals 1. H. periops, Gthr. 



Scales in 15 rows ; ventrals 178-180 ; a single 

 prefrontal 2. If. preefrontalis, Mocq. 



4. Rana paradoxa, Mocq. 



Rana Kuhlii is a very variable species, and I have repeat- 

 edly drawn attention to the great development of the terminal 

 disks of its toes, which would warrant its removal to a distinct 

 genus if such a character were regarded as generic, as it used 

 to be in former times. This character appears to have led 

 Dr. Mocquard astray in describing specimens of this species 

 as a new form, R. paradoxa, to which he assigns a position 

 widely remote from R. Kuhlii. I have now before me one of 

 the types of R. paradoxa, and can state that it is identical 

 with R. Kuhlii, as I had suspected from the description. I 

 have described male specimens from Burma with the same 

 enormous head, in a paper * which has been overlooked by 

 Dr. Mocquard when dealing with the adhesive ventral disk of 

 certain tadpoles. 



5. Rana Whiteheads, Blgr. 



Doubts having been expressed as to the distinctness of this 

 species from R. jerboa, Gthr., I have compared two specimens, 

 male and female, received from the Paris Museum, with the 

 types of the latter species, and have no doubt as to the correct- 

 ness of the course followed by me. In R. jerboa the choanse 

 are considerably larger, the lateral fold is as well marked as 

 in R. erythrcea and continuous throughout, and the hind limbs 

 are much longer, the tibia measuring four fifths of the length 

 of head and body, as against two thirds in R. Whiteheadi. 



6. Ixalus nubilus, Mocq. 



The fact that all specimens of Rana natafrix from the 

 Philippines are devoid of vomerine teeth, as I am informed by
