37204. Slab showing the dorsal aspect of the imperfect skeleton ;

 greater portion of the carapace is absent. The type spe- 

 cimen; noticed by Mnrchison in the 'Trans. Geol. Soc' 

 ser. 2, vol. iii. p. 281, and described and figured by Bell

42287. Slab showing the ventral aspect of the nearly entire skeleton 

 (Fig.) of a young individual ; from (Eningen. Figured by 

 Winkler, op. cit. pi. xx. The whole contour of the cara- 

 pace is shown, and the shell and greater part of the caudal 

 region are also visible. The distinctive characters of the 

 plastron of this species are shown in the figures given by 

 Meyer in the ' Palaeontographica,' vol. ii. pi. xxx.

Chelydra decheni, Meyer \ 



Carapace much expanded posteriorly ; tail short ; epiplastrals 

 large and widely divergent posteriorly ; outer extremities of hyo- 

 and hypoplastrals greatly produced antero-posteriorly, that of the 

 hyoplastrals reaching as far forwards as the suture between the

42732. Slab of lignite showing the dorsal aspect of the nearly entire 

 (Fig.) skeleton of a young individual; from the Lower Miocene 

 (Upper Oligocene) of Eott, near Bonn. Figured by Meyer 

 in the ' Palseontographica,' vol. xv. pi. ix. fig. 1. This 

 specimen shows the skull, the greater part of the carapace, 

 the left manus, and the right hyoplastral, which has been 

 displaced. Van Breda Collection. Purchased, 1877.

 of the anterior part of the skeleton, together with frag-
