 adult, and that on the preceding page an immature bird 

 of this species. The subjoined figure shows the sternal 

 apparatus, the posterior portion of which is subject to some

 the foramen by which it is pierced. The specimen from 

 which this figure is drawn possesses a foramen on the right 

 side but none on the left.
