122 Mr. G. A. Boulenger on Reptiles and Batrachians 



This species is considerably larger than V. rasse. The 

 markings are not usually very distinct and the general colour 

 is suffused with fulvous. It may be distinguished from both 

 the preceding species by the absence of the transverse 

 markings on the underside of the neck. 



The skull differs only from that of V. rasse by its greater 

 size. 



Dimensions of a skull from Formosa (a small specimen): — 



Basal length 87 millim. ; zygomatic breadth 45; length of 

 palate from henselion 43 ; length of bulla 20 ; basioccipital, 

 breadth at condyloid foramen 12"7, breadth anteriorly 9; 

 greatest diameter of upper carnassial 10 ; least breadth of 

 palate between inner roots of carnassials 13. 



These dimensions are far exceeded in the other skulls, but 

 these are given as it is the only skull sufficiently perfect to 

 allow all the measurements to be taken on it. The largest 

 skull has a zygomatic breadth of 49 millim. and greatest 

 diameter of upper carnassial lO'O millim. 



This species varies less than the others ; the markings are 

 almost always indistinct and generally absent on the fore part 

 of the body. Swinhoe thought Formosan examples slightly 

 different, but the specimens in the British Museum do not 

 bear out that conclusion.

XVIII. — A List of Rejytiles and Batrachians from Ombaai, 

 East Indian Archipelago. By G. A. BOULENGEK, F.R.S. 



In a previous number of these * Annals ' * I contributed a 

 list of the Reptiles and Batrachians collected by Mr. Alfred 

 Everett in Lombok, Flores, Sumba, and ISavu. Thanks to 

 the exertions of the same traveller I am now able to supple- 

 ment our knowledge of the herpetology of that chain of 

 islands by giving a list of the Reptiles and Batrachians 

 obtained by him on Ombaai. All belong to known species.
