REPTILES AND BATRACHIANS FROM BAN DON, 

 KOH SAMUI AND KOH PENNAN. 



By H. C. ROBINSON, c.m.z.s., axu C. BODEN KLOSS, f.z.s. 

 The .small collection of Reptiles and Batrachians obtained in the 

 Siamese Province of Bandon on the east side of the Malay Peninsula 

 near its northern extremity and on the adjacent islands of Samui and 

 Pennan includes, as was to be expected, a relatively large number of 

 Tenasserim and Siamese forms. No new records for tlie Malay 

 Peninsula were obtained though the places visited were quite 

 unknown : but the collections, especially those from the islands, are of 

 interest from the point of view of distribution. As Mr. Boulenger's 

 recent volume summarizes all ovir knowledge of the reptiles, etc., of 

 the Malay Peninsula it has been unnecessary to cite other ref ei-ences. 



1. Trionyx huruni. Gray. 



Boulenger, Vertebrate Fauna of the Malay Peninsula: BeptiUa 

 and Ampliihia, p. 9 (1912). 



A fresh-Avater turtle obtained at Kao Nawng, Bandon, is 

 represented by the head only. Cranial characters however 

 appear to indicate that it is a member of the above species 

 which has only rai-ely been recorded from the Malay 

 Peninsula.

This extremely rare reptile only known from Kina Balu, 

 Borneo and Penang, appears to be fairly numerous on 

 Koh Samui whei-e nine specimens were obtained. It was 

 found both in houses and on the stems of coconut palms and 

 is diurnal in its habits.
