Sommerring Collection. Purchased, 1827. 



R. 1230. A considerable portion of the vertebral column, ribs, and 

 (Fig.) the left pelvis and hind limb of the same individual. 

 Figured by Sommerring, op. cit. figs. 8-10, and by Cuvier, 

 op. cit. pi. xxi. figs. 7-8, and pi. ccxlix. figs. 7-8. As 

 far as their crushed condition admits of comparison, the 

 vertebras appear to agree in all respects with those of 

 Clidastes (No. R. 473). The pelvis and hind limb also 

 accord very closely with the restoration of the same in 

 Clidastes, as given by Cope in the Rep. U.S. Geol. Surv. 

 Terrs, vol. ii. pi. lv., but the bone which is probably the 

 ischium is relatively larger and differently placed. 



Same history. 



37020. An imperfect skull provisionally referred to a large indivi- 

 dual of this species ; from the Kimeridgian of Solenhofen, 

 Bavaria. This specimen seems to accord with the skull 

 of Clidastes, figured by Cope, op. cit. pi. xiv. fig 1. 



Purchased, 1862. 



37016-7. The crowns of two teeth agreeing with those of the last 

 specimen ; from Solenhofen. Same history. 



21530. The crown of a similar tooth ; from Solenhofen. 



Purchased, 1847. 



Genus CLIDASTES, Cope l . 



Syn. Edestosaurus, Marsh 2 (teste Cope). 



Body greatly elongated. Premaxillas not produced into a rostrum. 

 Vertebras much elongated, with zygosphenes, which are placed but 

 slightly above the plane of the zygapophyses ; 8 in the cervical 

 region ; chevrons anchylosed to centra. Humerus short and broad. 

 The possibility of this genus proving identical with the preceding is 

 noticed under that head. All the species are of moderate or small size.
