record. The division of the caudal plate is too regular to 

 be looked upon as purely accidental. 



The locality from whence the specimen was brought is 

 sharply fixed. Dussumier himself on his travels in the 

 tropics collected it in the island of Aldabra (N.W. of Ma- 

 dagascar) the chief dwelling place of the closely allied 

 Testudo elephantina. 



A careful investigation of the tortoises still inhabiting 

 this group of small islands is however necessary definitely 

 to settle the question whether really two distinct species 

 of gigantic tortoises inhabit it or whether T. elephantina 

 and glgantea are merely varieties of the same species. The 

 young specimen in the Leyden Museum does not suffice 

 to make out whether any other corresponding difference 

 either in the endo- or exoskeleton really justifies us in look- 

 ing upon the two specimens of T. gigantea , which are as 

 yet on record , as specifically difi'erent from Testudo elephan- 

 tina , both having in that case developed into distinct 

 species by the fact of their being possibly isolated on two 

 difi'erent islands of the Aldabra group. 



The following enumeration of oriental Emydae, represen- 

 ted in the collections of the Leyden Museum , may here be 

 inserted because several authors still appear to retain doubts 

 as to the specific independauce of some of them, whereas 

 at the same time the localities from whence they were 

 brought may be worth recording. One of them was noti- 

 ced and figured by Giebel , who however failed to recognize 

 it as a distinct species, uniting it with Clemmys dentata. 

 It is here described under the name of that naturalist.
