30073. A right astragalus, perhaps belonging to an immature indi- 

 vidual of this species ; from Hordwell.

28234 q. The left astragalus ; from Debruge. 



Bravard Collection. Purchased, 1852. 



M. 2481. The left navicular ; from Caylux. Purchased, 1885. 



28241. The right metatarsus ; from Debruge. 



Bravard Collection. Purchased, 1852. 



28234 r. The right third metatarsal ; from Debruge.

M. 2439. The left third metatarsal ; from Caylux. 



Purchased, 1885. 



M. 2435. Numerous bones of the manus and pes ; from the Lower 

 Miocene of Ronzon, near Puy-en-Velay (Haute-Loire), 

 France. These bones agree precisely in size with those from 

 Debruge, but are in a less crushed condition ; the Ronzon 

 form was distinguished by Gervais as P. aniciense, but it 

 was suggested that it might be only a variety. 



Purchased, 1885. 



28234 S. Part of the axis vertebra ; from Debruge. 



Bravard Collection. Purchased, 1852. 



30034, 46020. Two imperfect specimens of the atlas vertebra, pro- 

 visionally referred to this species ; from the Lower Miocene 

 of Hempstead, Isle of Wight. These bones are too large 

 for Hyopotamus or Diplopus. The species does not appear 

 to have been hitherto recorded from the Hempstead beds ; 

 but from its occurrence at Ronzon it might be expected 

 there. Hastings Collection. Purchased, 1855. 



Palseotherinm medium, Cuvier *. 



The skull and teeth of this species were described by Cuvier 2 as 

 being rather larger than those of P. crassum 3 : the limb bones, pro- 

 visionally referred by the same writer to P. medium, are long and 

 slender, while those referred to P. crassum are short and stout, and

* In pi. xxx. fig. 7 of Gervais's ' Zool. et Pal. Fran$aises,' 2nd ed., some large 

 teeth are figured as P. crassum ; on page 108 they are, however, termed (the 

 plate is wrongly referred toasxiii.)P. indeterminatum ; and it is not improbable 

 that they really belong to a large individual of P. medium.
