by its trochle.T ; and from that of Pal(vocicovia bj' the broader 

 groove between the third and fourth trochlea;, the lower position of 

 the foramen in the same, as well as by the fourth trochlea being 

 shorter in relation to the second, which is placed more anteriorly, 

 and the more sudden distal expansion. The tibio-tarsus which 

 may belong to this genus differs from that of Ciconia by the appa- 

 rent less development of the intercondylar tubercle, which is con- 

 nected with the cctocondyle by a complete ridge, instead of being 

 separated therefrom by a notch. It is quite different from the 

 tibia referred to Pelargopsis.

A. 109. The distal extremity of the right tarso-metatarsus ; from 

 (Fir/.) the Upper Eocene (Lower Oligocene) Phosphorites of 

 Bach (Lot). The type specimen ; figured in woodcut 16.

Propelargus (?), sp. 



The undermentioned specimens may indicate a species of this 

 genus, there being no evidence to show that it is even distinct 

 from the one from the Phosphorites. The features in which the 

 tibio-tarsus differs from that of Ciconia have been mentioned under 

 the generic heading, and it certainly cannot be referred to Lepto- 

 ptihis. The tibio-tarsus referred to Pelargopais is smaller, with 

 a much deeper anterior intercondylar gorge.

31607. The distal extremity of the right tibio-tarsus ; from the 

 Lower Miocene (Upper Oligocene) of Allier. The trans- 

 verse diameter across the condyles is 0,019, and the 

 antero-postcrior diameter of the entocondyle 0,022.

31668. The proximal extremity of a right tarso-metatarsus agreeing 

 in relative size with the preceding; from Allier. This 

 specimen has also the characters of the tarso-metatarsus 

 of the Ciconiidce as distinct from the Gruidce.
