§ 1. Introduction (PI. XVII). — The original of the figures in this plate is the least 

 mutilated of a pair of scapulae which, from their condition, we consider to have belonged 

 to the same animal as many of the bones in the Taunton Museum belong, such as the skull 

 (Pis. VI, VII, VIII, IX), the jaws (PL X), the radius (PI. II, fig. 1), and many others, 

 which will be enumerated at the end of this Monograph. The condition of the epiphyses 

 and muscular impressions proves that, although the animal had reached its full growth, it 

 died before the ossification was completed in all parts. With the exception of a 

 mutilated fragment from Bleadon Cavern, and an equally imperfect piece of one belonging 

 to a whelp from the Mendip Cave, we know of no other British specimens : it appears 

 to be equally rare on the Continent. Its rarity may perhaps arise from its fragile 

 character. 



In fig. 1 we have represented the glenoid cavity [a), the distal edge of the spine [c], 

 the acromial process (/), with the overlapping lamina, which we term, from the name of 

 the muscle to which it gives attachment, the delto-acromial process (y). The extent also 

 is shown to which axillary border {i) extends beyond the plane of the inferior and 

 posterior edge of {a), as well as the base of coracoid process [d), the point of which is 

 broken away. Pig. 2 represents the superior or outer surface. The anterior and upper or 

 vertebral portion of the bone, and the upper third of the spine, are broken away, leaving 

 the glenoid cavity {a), the lower part of the spine (/andy), the axillary border {i), up to 

 the insertion of the teres major muscle, and the greater part of the infra-spinal surface (e), 

 n a very perfect state.
