nibited by Mr. Gray, was brought frora Dukhun by Lieut. Col. Sykes. 

 It was characterized as the 



Emys tentokia. Em, testd ovato-oblongd, olivaced ; dorso sub- 

 angulariler compresso ; scutellis subrugosis, vertebralium primo 

 quadraio, reliquis elongato-hezagonis carinatis postici productis 

 {tertio pracipue) tuberculatis , viarginalibus sternalibusqueJlavo 

 carinatis ; sterno subplano parum elevato. 

 Hab. m Indiae Orientalis regione Dukhun dieta, 

 A fouilh new species characterized by Mr. Gray was the 

 Emys platynota. Em. testd ov aid, convexd, fuscd; dorso coni- 

 planato ; scutellorum vertebralium primo lato hexagono ; margine 

 subintegro ; sterno plano ; capite luteo variegaio. 

 Hab. in India Orientali. 

 Long. testcp, 9 poli. 



The shell differs at first sight from all the other species of the ge- 

 nus by the flatness of the middle of the back, agreeing in that cha- 

 racter vvith Hydraspis planiceps, Bell. 



Mr. Gray also exhibited a specimen of the fresh-toater Tortoise 

 which he had described in his ' Synopsis Reptilium/ under the name of 

 Cistuda Bealii, from a dravving communicated to him by Mr. Reeves. 

 The examination of the specimen subsequently received from Mr, 

 Reeves has enabled him to ascertain that it is really an Emys, vvhich 

 is easily distinguishable from all the other knovvn species of that ge- 

 nus by the possession of tvvo eye-like spots on each side of the nape : 

 the shell is in form likę that of Em. vulgaris, Gray ; its colour is dull 

 olive, speckled vvith black as in Cistuda Europeea, Gray. The name of 

 the species will now necessarily be changed to Emys Bealii. 



With these Terrapins Mr. Reeves had also transmitted to Mr. Gray 

 three specimens of Cistuda Amboinensis, Gr&y, tvvo of vvhich, differing 

 very much from each other and from the typical species in external 

 form, vvere exhibited. 



The first is extremely heavy and solid, vvith a very high back. 

 It appears to have belonged to an old animal, as the platės are 

 worn nearly smooth ; its sternum is solid, flat, rounded beforeand 

 behind, and the gular and anai pairs of platės are each united into 

 one, leaving only a slight groove betvveen the gular pair, showing 

 vphere the division is generally placed. 



The second is very much depressed, expanded on the sides, so as 

 to be nearly orbicular, and is as vi'ide as it is long. This extension is 

 chiefly produced by the length of the costal platės, for the vertebral 

 ones are very narrovv, the front one being rather longer than broad, 

 and much narrovver behind. The sternum is very broad, flat, rounded 

 before, and slightly keeled behind. All the platės are separate, 



Colonel Sykes exhibited several pieces of the leaden pipes used 

 for the supply of water to his house, which were perforated by 

 having been gnavved by Rats,
