OTIDES 336 



has a biceps slip. In Eupodotis DenJiami the brevis tendon is 

 a broad fibrous, band spreading out after the ulnar muscles 

 and inserted on to humeral tubercle. In Eupodotis australis 

 and Houbara Macqueeni there is, in addition, a broad wrist- 

 ward slip which does not cross the fore arm. In Otis tarda 

 the extreme degree of complication is reached, for there is, 

 in addition to the structures described, a slight patagial fan 

 joining the longus tendon in the usual way. 



The anconcBus has a tendinous humeral head (at least in 

 Eupodotis australis and Otis tarda). Otis has no latissi- 

 mus dor si posterior. 



As in other three-toed birds, the deep flexor tendons are 

 completely blended. 



The glutceus maximus is large and quite covers the 

 biceps. 



The number of cervical vertehrw is sixteen, seventeen 

 {fide Gabow and Fuebeinger), or eighteen {Houbara Mac- 

 queeni). The atlas is notched. In Houbara Macqueeni at 

 any rate the eleventh to thirteenth cervicals have closely 

 approximated hsemapophyses. The last hsemapophysis is on 

 the Dl ; in the two vertebrae in front these processes are trifid. 



Five ribs reach the sternum, all of them with uncinate 

 processes. The sternum has two notches. There is neither 

 spina externa nor spina interna. 



In the skull the margins of the orbit are very sharp, as in 

 (Edicnemus and Bhinochetus. The interorbital septum is 

 not greatly fenestrate. The descending process of the lacry- 

 mal just comes into contact, but does not ankylose, with the 

 prefrontal process of the ethmoid. The niaxillo-palatine 

 processes are curved and shell-like. In Houbara Macqueeni 

 at any rate this bone reaches the jugal arch. The temporal 

 fossa is guarded by two long and spine-like processes of the 

 squamosal bones, as in gallinaceous birds, and much more 

 marked than in Bhinochetus. 



The procoracoid is of moderate size and does not reach 

 the clavicle. The two coracoids are not in contact at their 

 articulation with sternum. 



I place the bustards in a group by themselves, largely
