HYDRASPIS. 41 



Habit, in Brasilia. 



Cuvier indicates in his notes an Emys platycephala. Mer- 

 rem. If it is not a synonym of this species, I do not find it 

 in any of Merrem's works that I have seen. 



The wart on the neck of the specimen from which Ef. as ■ 

 pei'a of Cuvier is established, is rather larger than that of 

 the other specimens.

 liptica pallide fusca nigro radiata, scutello nuchali lineari,
