CHELOKEA, 



42886. Slab of rock showing the dorsal aspect of the imperfect 

 {Fig.) carapace, in a flattened condition ; from the Upper Miocene 



Fig. 17. 



Homopus areolaris, — Carapace and plastron. The + + indicate the termina- 

 tion of the axillary and inguinal buttresses. (From Boulenger's ' Catalogue 

 of Chelonians.') 



of CEningen, Switzerland. Figured by Winkler in his 

 ' Tortues Fossiles ' (Haarlem, 1869), pi. xxi. fig. 65. The 

 areolation of the dorsal shields is well shown in this 

 specimen, but still more clearly in the one represented in 

 fig. 63 of the same plate. In the figure the boundaries 

 of the bones are not indicated, but the contour of the 

 first four neurals and adjacent costals is clearly visible 

 in the specimen ; and these bones agree in all respects 

 with those of the existing form.
