MR. R. LYDEKKER ON A LARGE EXTINCT STORK. [NoV. 3, 



against 0,092 in the recent bone. lu its long and slender form, com- 

 paratively slight distal expansion, small and hook-like hyosternal 

 process, and recurved and lamelliform subclavicular process without 

 any perforation at its base, as well as iu the rounded anterior surface 

 of the shaft, the fossil coracoid exhibits all the distinctive characters 

 of the Giconiid(B. 



The metacarpus (B of figure) presents the same relative excess 



Propelargus (?) edwarclsi. — Ventral aspect of the right coracoid (A), and left 

 metacarpus (B). a, subclavicular process ; b, hyosternal process ; 

 c—d, sternal border. |. 



over the corresponding bone of Ciconia alba as exists between the 

 fossil and recent coracoids. It appears to agree in every essential 

 point of contour with the metacarpus of the White Stork. 



Had I these two bones alone to deal with, I should have been 

 disposed to refer them to Ciconia ; but since the above-mentioned 

 leg-bones of Storks found in the AUier Miocene present generic 

 differences from Ciconia, it is more probable that the specimens 

 under consideration are likewise referable to an extinct genus, — the 

 generic variations in the form of the coracoid and metacarpus being 

 frequently less well marked than in the bones of the leg.
