Descriptions of two neio species of Reptiles. 



[No. 3, 



less than 95 transverse series ! While in a specimen of Varanus 

 flavescens, in my possession, on the other hand, I find only 67 trans- 

 verse series (at most) instead of " 70," as given hy G-unther ! I find, 

 also, that V. lunatus has, more commonly, less than " 105" series ; 

 or, generally, about 103. The longest specimen of Varanus lunatus 

 in my possession, measures 2 feet, 9 inches ; and the longest specimen 

 of V. draccena, 3 feet 6 inches. 



It appears to be a law of nature, that the more terrestrial any 

 species of Varanus is, the greater in number, and the smaller in size, 

 are the transverse series of scutes, on the under side of the body ; and 

 the more aquatic any species of Varanus is, the lesser in number and 

 larger in size these series of scutes are.
