Family Cariamidae

Cariama cristata (Linn6) 



Family Otidae 



Information incomplete. Garrod (1873) notes the A-1 condition 

 in Houbara macqueeni, while Beddard (1898) reports that two species 

 of Eupodotis are B-4-d. 



Presence of the ligamentum botaUi may vary; the thoracic artery 

 is probably type 1, and the vertebrals and superficial cervicals prob- 

 ably have separate points of origin from the common carotid arteries.
