facet probably supported the small inner toe by its metatarsus directly. 

 The other two are more nearly on one plane, and are deeper than wide.

On account of the absence of corresponding parts, it is not possible to 

 be certain whether the individual above described belongs to the species 

 Eohasileiis pressicornis or not. It is possible that the bones belong to the 

 same individual as that described under the latter name, although the locali- 

 ties where they were found are about one hundred yards apart. At about 

 the same distance from both the above specimens I found a humerus, which 

 I describe briefly. The distal articular face is very oblique to the trans- 

 verse axis, but is about equally developed on opposite sides of the shaft. 

 The condyles are unequal, have parallel axes, and are hour-glass shaped, 

 with a shallow concavity. The supra-condylar fossae of opposite sides are 

 not very large nor deep. 



Measurements of humerus and ulna. 



Transverse diameter, distally 175 



Anteroposterior diameter of inner condyle 104 



Anteroposterior diameter of outer condyle 125 



Transverse diameter, olecranon 110 



The portion of ulna just measured belongs to a young individual found 

 near to the one above described as Eobasileus furcatus. It is represented on 

 Plate XXIX, Fig. 7. 



Belations. — Besides the difference in the development of the anterior 

 nasal tuberosities, which might be sexual only, this species differs from L. 

 cornutus in the simple naso-maxillary horn-cores, which want the interior 

 tuberosity of that species, and ia the fact that they are composed exclu- 

 sively on their inner sides of the nasal bones to the apex, the maxillaries 

 forming the outer face. JE. pressicornis has also a much wider and less 

 massive parieto-occipital basin, with lighter horn-cores. Minor differences 

 have been already mentioned.
