1310. The left astragalus of an Aurochs. 



1311. The right os calcis of an Aurochs. 



1312. The left os calcis of an Aurochs. 



1313. The left scapho-cuboid bone of a young Aurochs. 



1314. The left internal cuneiform bone of a young Aurochs. 



1315. The proximal two-thirds of the right metatarsal bone of an Aurochs {Urus 

 priscus) : it presents an unusual prominence of the inner border of the 

 anterior groove for the extensor tendon which traversed the middle of 

 that surface of the metatarsus, bending the groove obliquely outward. 



1316. The left metatarsal bone of an Aurochs {Urus priscus) ; showing the 



same character of the enlarged and produced inner border of the anterior 

 tendinal groove. This character might be regarded, if present in a 

 single example, as the effect of partial ossific inflammation, but I have 

 observed it in the metatarsal bone of an Aurochs from the freshwater 

 pleistocene deposits at Clacton, Essex, and in another larger metatarsal 

 from the drift gravel at Kensington. 



The following seven bones form part of the left hind-foot of the same indi- 

 vidual Aurochs. 



1317- The metatarsal or cannon-bone. 



1318. The proximal phalanx of the inner toe. 



1319. The proximal phalanx of the outer toe. 



1320. The middle phalanx of the inner toe. 



1321. The middle phalanx of the outer toe. 



1322. The ungual phalanx of the inner toe. 



1323. The ungual phalanx of the outer toe. 



1324. The proximal phalanx of the outer toe of the hind-foot of a young Au- 



rochs {Urus priscus). 



1325. A mass of breccia, with a fragment of the shaft of the tibia of a small or 



young Aurochs.
