Myoxus sansaniensis, Lartet 1 . 



This is a minute species, distinguished by the complex arrange- 

 ment of the enamel-folds of the lower molars ; the mandible is 

 imperforate. 



Hob. France. 



33274. Fragments of the mandible and maxillae (with teeth), and of 

 the humerus, femur, and tibia, with several complete 

 specimens of the calcaneum ; from the Middle Miocene of 

 Sansan (Gers), France. These specimens agree precisely 

 with those figured by Gervais in the Zool. et Pal. Franchises, 

 2nd ed. pi. xliv. Presented by M. Ed. Lartet. 



Myoxus murinus, Pomel 2 . 

 Syn. Brachymus ornatus, H. von Meyer 3 . 

 Myoxus obtusangulus, H. von Meyer *. 

 (?) Myoxm primeevm, Schlosser 5 . 



This species has not hitherto been recorded below the Lower- 

 Miocene horizon of St. Gerand-le-Puy. Schlosser has separated a 

 mandible from the French phosphorites under the name of M. 

 primcevus, that specimen being slightly larger than the typical 

 form, but apparently not distinguished by other characters. The 

 folds on the crowns of the cheek-teeth are comparatively simple, 

 and the angle of the mandible is perforated; whence it is not 

 improbable that the species belongs to the so-called genus Ellobius. 



Hob. France. 



M. 1629. The greater part of the right ramus of the mandible ; from 

 the Upper Eocene of Caylux (Tarn-et-Garonne), France.
