In this very important paper, based upon the examination of a 
series of embryos of Struthio, Sulci , Larus, Uriel, and Gallus, Miss 
Lindsay distinguishes between costal sternum and metasternum, the 
latter of which is, together with the posterior lateral process, of later 
date than the two costal halves. Through abortion of ribs the sternum 
undergoes an anterior and posterior shortening. The keel is an out¬ 
growth of the sternum of comparatively late phylogenetic date, and 
created for and by the attachment of the pectoral muscles. The median 
furcular apophysis and the occasional median anterior sternal apophysis 
(sometimes wrongly called manubrium') are similar structures of late date 
and entirely without connection with any ancestral interclavicle. Struthio 
does not possess the slightest trace of a keel, even during the embryonic 
stage, nevertheless the centres and boundaries of ossification in the two 
sternal halves have no phylogenetic significance, nor can we conclude that 
the Ostriches never did possess a keel.
