FOSSILS FROJI FOLKESTONE. 



567 



Mackie's collection. These are all the determinable fragments refer- 

 able to Elephas. 



. No. 18. Bison priscus. — A fine specimen of the cranial box, com- 

 prising the whole of the occipital, the condyles, the base of sphenoid, 

 and a considerable part of both temporal fossa? ; but the whole of 

 the frontal, and indeed all in front of the occipital crest broken off by a 

 very irregular fracture ; quite enough, however, remains of the occiput 

 and temporal fossse to determine the offset of the horns and to prove 

 that the species is Bison priscus. The sutures are so open as to 

 show that the animal, although adult, was not very old. The follow- 

 ing are the principal determinable dimensions : — 



Transverse diameter of the two occipital condyles 

 Transverse diameter of left condyle 



„ „ foramen magnum 



Vertical ditto about 



Height from summit of occipital crest to inferior border 



of foramen magnum ..... 



Width of occiput between terminations of temporal 



fossEe ........

No. 19. — Fragment of a horn-core, very much mutilated, and forming 

 the middle portion, probably of the right side, 10 inches long, and 

 11*5 inches where thickest. 



jSfo. 20. — Left scapula of a large Ruminant, showing the whole of 

 the glenoid surface, 1 the greater part of the salient crest and the thin 

 basal portion alone wanting. The rough muscular impressions prove 

 distinctly that it must have been yielded by a very old animal. The 

 following are the dimensions : — 



Transverse diameter of glenoid surface, 3'8 in. Antero-posterior ditto, 3*1 in. 

 Width of neck where constricted, 3-6 in. 



This scapula belongs probably to Bos priscus, but this determination 

 is approximative. 



No. 21. Bight scapula. — Corresponding very closely in general form 

 and fracture with the specimen last described, but of smaller size, and 

 somewhat different in form, being more slender and somewhat differ- 

 ently formed. It also shows the whole of the glenoid surface and the 

 greater part of the spine ; it is proved by the muscular rugosities to 

 have been yielded by an extremely old animal. 



Dimensions. — Transverse diameter of glenoid cavity, 33 in. Antero-posterior 

 ditto, 2 7 in. Transverse diameter at neck, 3 - 4 in. 



This specimen may be of the Irish Elk. The glenoid surface is 

 singularly perfect, and free from any show of rolling. 



No. 22. Large Ruminant. — Fine specimen, comprising the inferior 

 half of the left humerus of a large Ruminant, most probably Bos 

 priscus. The only deficiency is in a portion of the outer articular 

 surface by recent injury. 



Dimensions. — Width of articular surface, lower, 4-4 in. Antero-posterior 

 diameter of outer condyle and tuberosity, 4-5 in. Girth of shaft, 8'5 in. Width 

 of fissure behind, for hook of olecranon, 1*3 in. 



1 The glenoid surface of this specimen 

 is as perfect as if it had been I hat of a 



recent animal. There is no mark of 

 gnawing or rolling.
