Pelargopsis magna, Milne-Edwards \ 

 The type and only described species. Of the approximate size of 

 Ciconia alba. 



Hah. Europe (France). 



27632. The proximal extremity of a left humerus, probably refer- 

 (Fin.) able to this species ; from the Lower Miocene (Upper 

 Oligocene) of Puy-de-D6me. This specimen (fig. 17) 

 agrees in size with the humerus of Ciconia alba, and 

 thereby accords in relative proportions with the type 

 tarso-metatarsus figured by Milne-Edwards in his 'Oiseaux 

 Fossiles de la France,' pi. Ixxii. figs. 4-6. The general 

 characters of the bone, especially the deep coraco-humeral 

 groove on the palmar aspect, the form of the head, the 

 groove between the latter and the trochanter or ulnar 

 tuberosity, and the form and position of the facet for the 

 attachment of the pectoralis minor, are essentially Cico- 

 nioid. Although nearer to the humerus of Tantalus than 

 to Ciconia, the closest resemblance is with species of Ibis 

 like /. longirostris ^, as is shown by the depth of the groove 

 between the head and ulnar tuberosity, the large size of the 

 subtrochanteric fossa, and the triangular section of the shaft 

 below the proximal extremity. The ridge on the dorsal 

 aspect of the shaft does not, however, continue close up 

 to the facet for the pectoralis minor as it does in Ibis.

27631. Slab of rock showing the dorsal aspect of the proximal 

 extremity of a similar humerus of the right side ; from 

 Puy-de-D6me. Croizet Collection. 



Genus AMPHIPELARGUS, Lydekker (n. gen.). 



Known only by the distal portion of the tibio-tarsus, which 

 approaches the Gruiclce in the lateral expansion of its articular 

 surface and the width of the trochlear groove, although agreeing 

 with other Ciconiidce in the prominence of the bridge over the 

 extensor groove, the concavity of the outer surface of the ectocon- 

 dyle, and the median position of the intercondylar gorge.

^ The humerus of this species is peculiar in having an ectepicondylar process.
