﻿144 PLEISTOCENE MAMMALIA. 



Bleadon, Hutton, and Sandford Hill. An ulna from the latter cave must from its 

 extreme shortness have belonged to a very young animal. In Mr. Beard's collection, now 

 in the Taunton Museum, are two right fibulae, the larger of which we figure (PI. XXII, 

 fig. 9), with some doubt as to its correct determination. Its ridges, which are slightly 

 developed, and the distal lateral articulations for the tibia, are of the same form as in the 

 older Lion. So far as we can tell, from the limited means at our disposal, it is of the size 

 of a Lion's whelp six weeks old. In the same collection there are both ends of a left radius 

 which correspond exactly with those of a young Lion of three months. They most probably 

 were obtained in Hutton Cave, which has furnished two young humeri, one of which is 

 figured (PL XXII, fig. 1), a large portion of a right scapula, both ulnae (one figured, 

 figs. 2, 3), both femora (figs. 7, 8), a left tibia, calcaneum (fig. 10), a fifth metacarpal 

 (fig. 4), and some first and second phalanges (figs. 5, 6), including a part of the first 

 digit of the fore paw. All these bones in size and proportions agree with those of a Lion's 

 whelp of three months. Erom Hutton also were obtained the maxillary and lower jaw, 

 which have already been figured (PI. XIII, figs. 1, 3), and described. The whole of them 

 most probably belonged to one individual. The calcaneum and some phalanges of an older 

 animal from Bleadon are also preserved in the Taunton Museum. All these bones coincide 

 with those of the adult which we have figured and described in the course of this Mono- 

 graph. They are, however, much more cylindrical, and present fainter muscular im- 

 pressions, and are considerably shorter. 



§ 2. Measurements. — The following measurements are all that the condition of the 

 bones would admit of being taken. Humerus : minimum circumference, 305 ; do., 3"04. 

 Ulna: minimum circumference, 2 - 20; length of humeral articulation, 2 - 00 ; length of 

 radial articulation, 1 - 15 ; depth of radial articulation, - 40. A second specimen agrees 

 with the preceding while in a L third the minimum circumference is 2-20, and the length 

 of the humeral articulation, 1-70. Radius: minimum circumference, L40. Femur: 

 minimum circumference, 2-78 ; do., 277. Tibia : minimum circumference, 2'60. 

 Eibula : minimum circumference, 0-50 ; do., 0"60.
