Cautley Collection. Presented, 1840. 



Genetically Undetermined Specimens. 



Of the following specimens from the Upper Eocene (Lower Oli- 

 gocene) Phosphorites of Central France, it is probable that the ma- 

 jority are referable to land forms such as Testudo, Stylemys, or 

 Ptycliogaster. 



R. 384. A left scapula ; from Caylux (Tarn-et-Garonne). The pre- 

 coracoid is broken. The specimen indicates a form of the 

 approximate size of Testudo radiata. Purchased, 1884. 



R. 385. The imperfect left scapulo-precoracoid of a smaller tortoise ; 

 from Caylux. Purchased, 1884. 



R. 421. A right humerus, wanting the distal extremity; from 

 Bach, near Lalbenque (Lot). This specimen would agree 

 in relative size with jSTo. R. 384. Purchased, 1884. 



R. 421 a. A rather smaller right humerus, wanting the distal ex- 

 tremity ; from Bach. Purchased, 1884. 



R. 421 b. An apparently similar right humerus, wanting the 

 proximal extremity ; from Bach. Purchased, 1884. 



R. 424. A much smaller right humerus, wanting the distal ex- 

 tremity ; from Bach. Indicates a form of the approxi- 

 mate size of Clemmys leprosa. ■ Purchased, 1884. 



R. 424 a. A slightly smaller right humerus ; from Bach. 



Purchased, 1884. 



R. 424 b. Two nearly similar left humeri ; from Bach. 



Purchased, 1884. 



R. 1301. A left femur, agreeing approximately in relative size with 

 the humerus No. B. 421 ; from Bach. 



By exchange, 1888. 



R. 422. A smaller right femur ; from Bach. Purchased, 1884. 



R. 383. A still smaller right femur ; from Caylux.
