Summary

Description

Skulls of Falconiformes Ventral aspect of the skull

  • Left.Skull of Elanus caeruleus. The palate is schizognathous. Herein the maxillo-palatines have increased in size, whilst the septo-maxillary spurs have completely disappeared. The nasal septum is more complete than in Catharistes and may be seen lying in the middle line of the anterior palatal vacuity. Above the inflated region of the maxillo-palatines it sends downwards a feeble pair of spurs which nearly touch the maxillo-palatines. The basipterygoid processes are represented only by a pair of minute prickles.
  • Right. Skull of Falco minor. The palate is completely desmognathous. Note the peculiar form of the vomer, and its relation to the maxillo-palatines. The antrum of the maxillo-palatines is reduced to the merest vestige.

A.p.v. = anterior palatal vacuity.
bp.p. = basipteiygoid process.
mx.p. = maxillo-palatine process.
n.s. = nasal septum.
p.a. = palatine.
