1/6 DR. J. E. GRAY ON THE BOX TORTOISES. [May 12, 



Cuora trifasciata, var.. Gray, Cat. Shield Reptiles in B.M. p. 42. 

 Specimen c. 



Hab. China {J. Reeve, Esq.) ; Formosa (i2. Swinhoe, Esq.). 



The surface of the shell is often more or less eroded ; the one 

 which we first received from Mr. Reeve was so on the whole upper 

 surface. The form of the foot, as well as the height and thickness 

 of the shell, at once separates this species from Cuora trifasciata, 

 with which I formerly confounded it. 



Mr. Swinhoe informs me that this Tortoise is very abundant in 

 the ponds in the district of Tamsuy, N.W. Formosa. He did not 

 fall in with it in South Formosa, where the Etnys bennettii* is the 

 prevailing species. He has frequently seen the Tamsuy Tortoise 

 showing its head and the top of its back on the surface of the water 

 in ponds about the rice-fields, and has watched them basking, several 

 at a time, on the tops of large stones in such ponds. 



iii. The hind feet flattened, fringed ; toes webbed and with band- 

 like shields above. 



4. CuORA. 



The thorax rather convex, more or less three-ridged. The sternum 

 flat ; lobes subequal, both enclosed in the symphysis. Head flat at 

 top ; eyes lateral. The front of the fore legs with large scales. The 

 toes all banded above, webbed. The claws conical. The hind feet 

 depressed ; the hinder edge fringed and angularly produced. Asiatic. 



* The head large, flat, with two yellow streaks on each side ; back 

 one-coloured ; toes broadly webbed. Cuora. 



Cuora amboinensis. Gray, Cat. Shield Reptiles B.M. p. 41. 

 Hab. Amboina; Gilolo ( ^a/^ace) ; Borneo {Wallace). 



** Head smaller, oblong, with two dark streaks on each side ; back 

 three-banded ; toes narrowly webbed. Pyxiclemmys. 



Cuora trifasciata. Gray, Cat. Shield Rept. B.M. p. 42. 

 Hab. China. 



5. LUTREMYS. 



Thorax depressed. Sternum flat ; lobes subequal, both enclosed 

 in the symphysis. Head ovate ; eyes superior. The legs with large 

 scales in front. The feet depressed ; toes webbed, banded above ; 

 the hind feet fringed and angularly produced behind. Claws elon- 

 gate, acute. 



LuTREMYS EUROPiEA, Gray, Cat. Shield Reptiles B.M. p. 40. 



Hab. Europe. 



Very variable in colour. 



* Emt/s sinmisis proves to have been founded on the young state of this species, 

 as is shown by the fine series of specimens brought from Formosa by Mr. Swinhoe.
