50 Catalogue of Reptiles inhabiting the 



Habit. — Piuang. 



Singapore, Java. 

 But two individuals were observed on the Great Hill of Pinang, oua 

 by Sir W. Norris, the other by myself. The latter made its appearance 

 through a hole in the soft, moist mould beneath a group of Polympo- 

 dium horsfeldii. Above ground its movements were very quick, ser- 

 pent-like, apparently little assisted by the tiny limbs. The head of 

 the larger measured f inch, the trunk 2| inches in length. One 

 had but 4 toes on the anterior feet. In both the tail was reproduced, 

 which is also the case in a third, from Singapore, preserved in the 

 Museum of the Asiatic Society.
