the following obsen'ations on this species, which appears to have 

 been mentioned* in a preceding volume : — 



Testudo elongata, Blyth, Journ. As. Soc. Bengal, xxxii. 639. 

 Vol. XXV. 1856, lxxviii. 712. 



Mr. Blyth statės, " a number of living specimens have been re- 

 ceived from Captain Berdmore. 



" Colour of naked parts olive-grey varied with dull yellow, and 

 with black head conspicuously dull yellowish white." 



Mergui, Tenasserim River. 



2. Testudo Horsfięldi, Gray, Cat. Tort. B. M. t. 1. 



There is a fine large specimen of this species, showing it is very 

 distinct from the T. grcBca of Europa. The upper jaw has a small 

 notch on each side of the tip. 



3. EmYS CRASSICOLLIS, Bcll. 



The Collection contains three adult specimens of this species, which 

 are marked "Emys nigra, Blyth." 



The adult examples are rather broader than the younger specimens 

 in which are usually found a raucro, and the dorsal keels are almost 

 entirely obliterated ; the hinder edge of the thorax is acutely dentate ; 

 the sternum is pale grayish, with black areolse and rays. It is probably 

 the absence of the keels in the adult statė that induced Mr. Blyth 

 to regard it as a distinct species ; but the keels become generally 

 more indistinct in all the species which are keeled in their younger 

 condition. 



The specimens are marked as coming from " Mergui." The jaws 

 are even, and not notched in firont. 



4. Emys nigra, n. s., Blyth, Journ. As. Soc. Bengal, lxxviii. 712. 



Mr. Blyth obserses on the affinity of this species with E. crassi- 

 coUis, but he does not appear to have the means of comparison. 



The Collection contains two species of the genus Batagur : — 



5. Batagur baską, Gray, Cat. Tort. B.M. t. 16. 



There is a very large adult shell of this species, which is marked 

 "Emys tentoria, Blyth," It measures 21^ inches over the back, 

 19į along the sternum, and is 18 inches across the back aud 21į 

 over the convexity of the back. The jaws of the species are very 

 strongly dentated, the upper one is toothed on the edge with two 

 angular series of pits ; the lower jaw is furnished with two concentric 

 series of acute spinose tubercles, those in the outer series the largest 

 and very acute, the centrai one in front horny, very large. 



6. Batagur ocellata, Gray, Cat. Tort. B.M. t. 36. (PI. X.) 



There is a beautiful specimen of a species of this genus from 

 Mergui, which I am incUued to beUeve is referable to Emys ocellata 

 of DumerilandBibron(Erpetologiegenerale, ii. 329. 1. 15. f. 1); a spe- 

 cies which I have not before seen in any Enghsh collection. I should
