projection in region of 



uncinates. 



8th sternal rib short and 



does not reach sternum. 



Penultimate 6ternal rib 

 plain. 



V-shaped ; broadest region 

 ju 3 t beyond coracoid. 



Clavicle 



Pelvis Ilea cover fourth but last 



ribs ; hinder part of 

 pelvis is bent down on 

 the fore part (see fig. 6, 

 p. 554). ' Waist ' of 

 pelvis very broad. 

 Wings Proportionately much lon- 

 ger and bones slighter. 

 This especially so with 

 second metacarpal. 

 Legs Femur and tibia more slen- 

 der ; fibula and digits 

 much longer. 



Cervical vertebra; 16. 



A'entral processes of anterior 

 cervic.ils much less marked. 



Dorsal vertebra? First pair have a ventral 



process. 

 Neural processes flatter and 

 higher. 



Ploughshare bone More short and slender. 



Skull In proportion and absolutely 



much smaller. The horn 

 arises from a bony process 

 on middle line, a quarter 

 of an inch from the 

 anterior margin. Flatter. 

 Foramen magnum larger. 

 The anserine oval space 

 between periotics and 

 supraoccipitals absent. 

 Anterior part of the face 

 from tip of bill to end of 

 palatines broad, long, and 

 goose-like. 

 Desmognathous. 

 Outer long edge of palatine 

 with a sharp angular 

 projection as in Geese. 

 Basipterygoid facets wide 

 apart, not close together 

 as in Geese. 

 Middle superior ramus of 

 premasilla separate from 

 the lateral pieces as in 

 gallinaceous birds, not 

 1 used as in Geese. 

 Angulare of lower jaw nearly 

 straight. 



Ohaujta dekbiana. 



8th sternal rib articulates 

 with costal rib and with 

 sternum. 



Penultimate sternal rib has 

 a sharp backwardly direc- 

 ted process near articu- 

 lation with costal rib. 



U--haped ; broadest region 

 hallway down from cora- 

 coid. 



Ilea cover third but last rib ; 

 long axis of pelvis straight 

 and more duck-like. 

 Waist narrow.
