THE EEPTILES AND BATRACHIANS OF THE NATUNA 



ISLANDS. 



By DE, a. GUNTHEE, F.E.S. 



ri"^HP] collections made by Mr. A. Everett and .Mr. Ernest Hose during their visits 

 -L to the Natuna Islands must be regarded as rich, considering the short time 

 they were able to devote to their exploration. There is no doubt that future visitors 

 will be able to add to the following lists of species, but it is not likely that such 

 additions will modify the views which can be formed from these collections as regards 

 the general character of the Keptilian Fauna of this group of islands. It is a 

 mixture of species inhabiting the large islands and countries bordering upon the 

 southern half of the China .Sea, in the midst of which the Natuna group is situated. 

 The future must show whether the two new forms of Frogs described at the end of 

 this paper are peculiar to the Natunas, or whether they will be rediscovered in some 

 other part of Borneo or the JIalayan region. 



TORTOISES. 



1. Cyclemys amhoinensis Baud. Great Nat una. 



2. Cyclemys dhor Gray. Great Xatuua. 



3. Geoemyda spinoBa Gray. Great Natuna. 



4. Trionyx subplanua Geoflfr. Great Natuna. 



5. Chelonia inihricata L. Great Natuna. 



These Chelonians have a rather wide range of distribution, and do not indicate a 

 special relation of the Natuna Fauna to either that of the Malaj'au Peninsula or of 

 Borneo.
