Myoxus sansaniensis, Lartet’. 
This is a minute species, distinguished by the complex arrange- 
ment of the enamel-folds of the lower molars; the mandible is 
imperforate. 
Hab. France. 
33274. Fragments of the mandible and maxillz (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. Frangaises, 
2nd ed. pl. xliv. Presented by M. Hd. Lartet. 
Myoxus murinus, Pomel’. 
Syn. Brachymus ornatus, H. von Meyer *. 
Myozus obtusangulus, 1. von Meyer *. 
(?) Myoxus prumevus, Schlosser *. 
This species has not hitherto been recorded below the Lower- 
Miocene horizon of St. Gérand-le-Puy. Schlosser has separated a 
mandible from the French phosphorites under the name of MZ. 
primevus, 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 Hlobius. 
Hab. France. 
M. 1629. The greater part of the right ramus of the mandible; from 
the Upper Eocene of Caylux (Tarn-et-Garonne), France.
