152 CHELONIA. 



the present specimen the carapace has been crushed almost 

 completely flat. The cranium is distinctly seen to have 

 the temporal fossae only incompletely roofed over, and the 

 orbits appear to have been approximated to the nares. 

 The flutings on the areas occupied by the vertebral shields 

 are distinctly visible. Purchased, 1878. 



49177. Cast of a slab of limestone showing the middle of an imma- 

 ture carapace apparently referable to this species. The 

 original was obtained from the Lower Kimeridgian of 

 Solenhofen, Bavaria, and is preserved in the Museum at 

 Munich. It is figured by Wagner in the ' Abh. k.-bay. 

 Ak. Wiss.' vol. ix. pi. ii., as JEuryaspis radians, of which 

 it is the type. It is provisionally referred to the present 

 species by Eiitimeyer in the ' N. Denkschr. schw. Ges. 

 Nat.' vol. xxv. art. 2, p. 140. The original contour of 

 the carapace is preserved, and is seen to be distinctly 

 convex. The boundaries of the neural bones are invisible ; 

 but the flutings on the area occupied by the vertebral 

 shields are very distinct. The hinder neurals are slightly 

 ridged. Purchased, 1878. 



49158. Cast of a slab showing the dorsal aspect of a young skeleton 

 belonging to the present genus. The original was obtained 

 from the Lithographic Stone of Kelheim, Bavaria, and 

 is figured by Maack in the ' Palseontographica,' vol. 

 xviii. pi. xxxix. (vii.), as Eury sternum crassipes. By Eiiti- 

 meyer it is identified, in the ' N. Denkschr. schw. Ges. 

 Nat.' vol. xxv. art. 2, p. 140, with Aplaoc oberndorferi. 

 Zittel regards it as specifically identical with the young 

 skeleton already mentioned and figured by himself in the 

 ' Pala3ontographica,' vol. xxiv. pi. xxvii., under the name 

 of Eury sternum wagleri. The right humerus shows a very 

 small and imperfectly differentiated head, in which respect 

 it differs from the humerus of Paraclielys, and resembles 

 the specimens mentioned on p. 157. The peculiar form 

 of the neural bones as given in Maack's figure is probably 

 due to incorrect restoration. Pur chased, 1878.
