ANATOMY OF VERTEBRATES. 



•In true Ruminants the spine of the scapula is not produced, 

 as in CamelidcR, but terminates in an acute {Bos) or a right 

 angle {Cervus): the Musks and Chevrotains agree Avith the 

 horned families in this character, but the coracoid is a better 

 defined process in the latter : in all, the scapula is a long slen- 

 der triangle, with two equal or subequal sides, the infraspinal 

 division chiefly expanding to the base, which is truncate in Bos, 

 fig. 309, Antilope and Cervus, fig. 311 ; but rounded oif at the 



hinder angle in Camelopardalis, 

 fig. 310 ; in this Ruminant the 

 cervix scajDulte is unusually long. 

 The humerus, fig. 330, A, is 

 short, but strong, with slightly 

 expanded ends : the outer tu- 

 berosity, at the proximal one, 

 rises above the head of the bone, 

 and bounds, with the inner tu- 

 berosity, a deep bicipital groove: 

 the deltoid crest, i, is less pro- 

 minent than in the Horse. The 

 distal articular end presents 

 three prominences answering to 

 the hollows of the head of the 

 radius, the internal one being 

 the broadest and lowest. The 

 supracondylar ridges are but 

 little produced: the olecranal 

 fossa is deep, and perforated in 

 Musk-deer, Chevrotains, and 

 Microtheres, as in the Hog- 

 tribe. In the Gnu (^Antilope 

 Gmi) the humerus is as long 

 as the metacarpus : in the Ox, 

 fig. 309, it is longer ; in the 

 Giraffe, fig. 310, and Gazelle, 

 fig. 330, A, it is shorter. The 

 radius, fig. 330, A, 2, is the chief 

 bone of the antibrachium : its proximal trochlear surface offers 

 three eminences and as many depressions to the humerus, restrict- 

 ing the movements of the fore-leg to one plane. The shaft is 

 slightly bent forward : the distal end is moulded to the irregularities 

 of the carpus, and is most impressed by the scaphoid, especially
