usual segments, each separated from its fellow by a considerable plate 

 of cartilage. In the older lion there is an additional, small, rounded 

 nodule of bone between the seventh and eight segments, and in line 

 with the articulation at the ventral end of the ninth rib-cartilage. 



Skull. Concerning the skull little need be said but that all the 

 sutures, with the exception of the lambdoidal, are present. In the 

 older animal the lambdoidal suture has partially disappeared. So far 

 as can be made out from an examination of the intact skull, the eth- 

 moid is very imperfectly ossified ^). 



Scapula. A strip of cartilage runs along the vertebral border 

 of the scapula, but there is no evidence of an ossific centre or centres 

 in it. With the exception of the acromion, all the rest of the bone 

 is fully ossified. In lion No. 1 an epiphysis is present on the acro- 

 mion in the form of a rather thin plate of bone of rounded outline, 

 which is placed on the surface rather than at the end of the process 

 (Fig. 3), and which, though its limits are very obvious, is joined to 

 the rest of the scapula by bone. In lion No. 2 its union is still more 

 intimate, though its extent remains determinable. 



Clavicle. In both animals this bone has evidently attained its 

 full development. 



Humerus. The ossific centres at the proximal end have joined 

 together to form one common, 



readily removable epiphysis ^ ^ j^ead.

1) The presence of additional ossicles in the skull of lion No. 1 

 has already- been commented upon (Anat. Anz., Bd. 27, 1905, p. 317).
