" Tlie hinder nose-leaf is bristly, ovate-lanccolafe, nearly as broad 

 at the base as the face, vvith a rather pioduced tip; the septum of the 

 nose is grooved ; and the front leaf expanded vvith a quite free mem- 

 branaceous edge. The head is elongated ; the face depressed ; the 

 muzzle rounded ; the ears are large, reaching \vhen bent dovvn 

 rather beyond the tip of the nose. The fur is soft and of a pale 

 mouse colour. The membranes are dark and naked, with rather di- 

 stant whitish hair on the under side near the sides of the body, 



♦' This Bat is very nearly allied to the true European Rhinolophi, 

 and agrees with them in having four cells at the base of the hinder 

 nose-leaf, and distant pectoral teats. It diflers from them in having a 

 much broader nose-leaf. The pits on the nose and the distant teats 

 are not found in the other Rhinolophi, vvhich have no hinder nose- 

 leaf. These I propose to separate irom the others under the name 

 of Hipposiderus." 



Mr. Gray also exhibited specimens of seveT&\fresh-water Tortoises, 

 Of these he had recently received three from John Russel Reeves, 



Esq., of Canton, two of vvhich he regarded as being previously un- 



described. These he novv characterized as follovvs : 



Emys nigricans. Em. testd obovato-oblongd, convexd, nigro- 

 fuscd ; subtricarinatd, carind mediand obtusd postici continud, 

 lateralibus indistinctis distanfibus ; scuteUis obscure radiatis, ver- 

 tehralibus latis, anterioribus pentagonis ; viarginibus revolutis, 

 posticd subserratd ; infrci ad latera luleo maculatd ; sternum sub- 

 conveium, luteum, nigro variegatum. 

 Long. tesl<B, 3 poli. 

 Hab. in China prope Canton. 



This species is nearly allied in shape and colour to Em. cras$i- 

 colits, Bell, bot differs by the distance and indistinctness of its la- 

 teral keels, the convexity of its sternum, and the shape of its anterior 

 vertebral platės. From Em. Thurjii, Gray, it is distinguished by its 

 smaller size, the darkness of its colour, and the yellovv spotting 

 on the under side tovvards the edge of the sliell. 



The character is taken from a half-grovvn shell, from vvhich the 

 animal had been removed. 



Emys Sinknsis. Em. testd ovatd, convexd, suhcarinaid, otivaced 

 nigro punctatd ; scuteUis lavibus, luteo strigatis, vertebralibus 

 latis hexagonis ; marginibus integris, lateralibus subrevolutis į sub- 

 tūs luted, maculis oblongis olivaceis nigro marginatis ornatd ; 

 sterni lateribus subcarinatis : colio lineis tenuissimis Jlavis notato. 

 Long. testcE, 5 poli. 

 Hab. in China. 



Allied to Em. vulgaris, Gray, but easily distinguished by the 

 orange streaks in the centre of each discal shield. The under side 

 of each of the marginai platės is marked near its hinder edge by a 

 large oblong subąuadrate olive spot, vvhich is dotted and margined 

 vvith black ; the axillary and inguinal platės are marked vvith a black 

 ring. The sternal platės are varied vvith brovvn.
