3. Bones of the Extremities. 
(A) Scapula and fore limbs.—Whilst the shoulder-blade shows 
no special specific or generic mark, it yet, I would say, is impressed 
more with Antilopine than Ovine form. This, I think, is owing to its 
somewhat greater length to breadth and upturned axillary border. 
Its long diameter is 7, and breadth at vertebral end 33 inches. The 
supra- is about a third of the breadth of the infraspinous fossa ; 
the spine has a concavity towards the latter; the acromion process is 
obsolete, a tubercle of bone alone representing it. There is a well- 
marked neck, flattish and widened by a flange of bone at the axillary 
border. The glenoid cavity is shallow, incised at the coracoid end, 
this process being short and broad. The tricipital border is thick, 
wide, and markedly grooved, and towards the vertebral end rises at 
a right angle to the plane of the infraspinous fossa in a prominent 
strong plate of bone for the attachment of the teres major muscle. 
The cartilage at the spinal end was semiossified in the male specimen. 
The shaft of the humerus is roundish, but with a tendency to 
posterior angularity. Head and neck relatively to the shaft are 
massive. The great tuberosity is very broad, strong, and thick, 
obliquely salient inwards. The deltoid eminence and elevation for 
attachment of the teres major are each well developed. The bicipital 
groove is flattish and unusually broad. The articular capitulum is 
deflected posteriorly, its upper surface being moderately convex and 
broad ; the inferior extremity presents little or no difference from 
that of the Sheep. 
There is a moderately broad shaft to the radius, which has a slight 
bend forwards, and, as usual, is convex in front, but almost flattened 
behind. The stout olecranon rises 2 inches above the radius; and 
the shaft of the ulna is represented by a slender rod continued to 
the short styloid process, where it somewhat widens out. 
The carpal bones consist of the usual ruminant number, 6, viz. the 
scaphoid, semilunar, cuneiform, and pisiform in the first row, and 
os magnum (with united trapezoid) and unciform in the second. 
Proximately the scaphoid, lunar, and cuneiform are arranged in a 
close-fitting semilune, the pisiform bone being, as it were, accessory, 
placed posteriorly and comparatively free. The magnum and unci- 
form form an inferior and reduced semilune, modelled accurately to 
the upper surface of the metacarpal pillar. A sufficient hollow is 
provided behind these bones for the tendons &c. to be bound firmly 
by transverse ridges of fascia, and enabling them to play with secu- 
rity during the frequent jerking movements of this part of the limb 
when in action. 
The scaphoid, of good size, has an upper deepish median hollow 
which lodges the greater part of the inner facet of the radius. The 
said hollow is somewhat laterally constricted, but posteriorly rises as 
a tuberosity. The underside of the scaphoid occupies more than 
the outer moiety of the connate os magnum and trapezoides. The 
uneven outer side of the bone rests in the corresponding rough con- 
cavity of the lunare.
