XIV. — On the Herpetological Fauna of Palawan and Balabac. 

 By G. A. BOULENGER, F.R.S. 



In his valuable paper, " On the Zoo-geographical Relation- 

 ships of the Island of Palawan and some adjacent Islands " *, 

 Mr. A. Everett has shown that Palawan, together with other 

 islands west of Mindoro Straits, should be regarded as forming 

 part of that district of the Indo-Malayan subregion to which 

 Borneo belongs, as its fauna has much more in common with 

 that of the latter island than with the Philippines proper. His 

 conclusions were derived from a study of the mammals and 

 birds. Of the reptiles and batrachians very little was known 

 at that time. A new snake from Palawan (Gallophis bilinea- 

 tus) had been described by Peters in 1881, a new toad by 

 myself in 1887 (Bufo philippinensis) , and a widely distri- 

 buted Agamoid lizard {Calotes cristatellus) had been recorded 

 in the British Museum ' Catalogue of Lizards.' A list of 

 eight species has since been contributed by Dr. Mocquard 

 (Nouv. Arch, du Museum [3] ii: 1890). Thanks to an 

 important collection made for the British Museum by 

 Mr. Everett himself on Palawan and Balabac, we are now 

 able to draw up the following list of the species of reptiles 

 and batrachians represented on these islands. Mr. Everett's 

 conclusions are entirely confirmed so far as these classes of 

 animals are concerned.
