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 fibula, 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 ulnz (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. From Hutton also were obtained the maxillary and lower jaw, 
which have already been figured (Pl. XIII, figs. 1, 3), and described. The whole of them 
most probably belonged to one individual. ‘The caleaneum 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. IMWeaswrements.—The following measurements are all that the condition of the 
bones would admit of being taken. Humerus: minimum circumference, 3:05; do., 3°04. 
Ulna: minimum circumference, 2°20; length of humeral articulation, 2:00; length of 
radial articulation, 1:15 ; depth of radial articulation, 0°40. A second specimen agrees 
with the preceding while in a third the minimum circumference is 2:20, and the length 
of the humeral articulation, 1:70. Radius: minimum circumference, 1°40. Femur: 
minimum circumference, 2°78; do., 277. Tibia: minimum circumference, 2°60. 
Fibula: minimum circumference, 0°50 ; do., 0°60.
