114 chelonia. 



Specimens op which some may belong to the next species. 



a. From tlie Upper Eocene {Lower Oligocene) of Hordwell. 



30410 g. The nuchal bone of an adult specimen. This specimen, 

 which was probably associated with the type hyoplastral, 

 agrees in all respects with the nuchal of the type of Emys 

 Jwrdwelliensis figured by Seeley in the ' Quart. Journ. 

 Geol. Soc' vol. xxxii. p. 446, fig. 1, but is of rather larger 

 size. It closely resembles the nuchal of Ocadia sinensis. 



Hastings Collection. 



38100. An immature nuchal. Figured by Owen in his ' K,eptilia 

 {Fig.) of the London Clay, &c.' vol. i. pt. i. pi. xxiv. fig. 1, without 



name l . In contour it agrees precisely with the preceding 

 specimen, while in size it accords with the 1st margnial 

 of No. E. 1562. Hastings Collection. 



R. 1563. A nuchal agreeing in size with the preceding specimen. 

 The dorsal part of the nuchal shield is very narrow. 



Hastings Collection. 



R. 1560. A series of eight neural bones and the anterior supra- 

 pygal, belonging to different individuals. These bones 

 are lettered consecutively a to h, according to their serial 

 position. They agree precisely with the corresponding 

 bones of the type of Emys Jwrdivelliensis, and also closely 

 resemble those of the existing Ocadia. The prominence 

 in the anterior sulci of the vertebral shields is well shown 

 on the 1st, 3rd, 5th, and 8th neurals. 



Hastings Collection. 



R. 1571. Numerous specimens of the 1st neural bone. 



Hastings Collection. 



R. 1572. Several specimens of neurals, of which the majority are 

 the 2nd of the series. Hastings Collection. 



R. 1566. Numerous specimens of neurals, the majority of which 

 are the 3rd of the series. Hastings Collection. 



38101. A 3rd or 5th neural (probably 3rd). Figured by Owen, op. 

 {Fig.) cit. pi. xxiv. figs. 2, 3, without name, and in a reversed 



position. Hastings Collection. 



1 The name Emys tcstudiniformis in the description of the plate is erroneously 

 made to include this and the undermentioned specimens figured in the same 

 plate.
