This they regard as " the adult of the E. pidcherrima, Gray, 

 Cat. Sh.Rept. B. M. 1855, t. xxv. fig. 1 (young)." 



It is described from a specimen said to have come from 

 Central America, which is living in the Menagerie of Reptiles. 



Only the external form and the colouring of the upper part 

 of the animal is figured ; and the description is so general that 

 it is impossible to determine to what subgenus this species 

 should be referred ; and I greatly doubt its being the adult of 

 my Emys pulcherrtma (from the colouring of the head, neck, 

 and feet), which is, by the structure of its sternum, a Rhino- 

 clemmys. The species described by Dume'ril and Bocourt, 

 from the shortness of the toes and the form of the streaks on 

 the head, may belong to the same genus. If it does, it is quite 

 a new species, characterized by the streaks of the head and 

 the broad orange streaks edged with black on the fore legs, 

 which separate it from all the species of Rhinoclemmys known. 

 I therefore propose to call it Rhinoclemmys Bocourti. The 

 colouring of the shell is somewhat like that of, but very dif- 

 ferent from, R. mexicana.

MM. Dume'ril and Bocourt observe that there are two speci- 

 mens of this species in the French Museum from the province 

 of San Francisco, California, sent by Professor Agassiz ; but 

 their description adds nothing to our knowledge of this species ; 

 they give the account of the synonyma. compiled for Mr. 

 Agassiz, which I believe contains two very different animals 

 confused together. 



Mr. Girard's figure very much resembles the animal which 

 I described in 1855, from a specimen I purchased at Nantes, 

 under the name of Emys olivacea, Cat. Sh. Rept. p. 30, 

 t. xii. c, and which I now call Redamia olivacea] and the 

 truth of this suspicion might have been confirmed if MM. 

 Dume'ril and Bocourt had given us the details of its palate.

who add nothing new to the account of this species ; indeed it 

 appears doubtful whether the authors had ever seen a specimen.
