2lquila cljn'saetu© (supm, p. 24 ). 

 A. 14. The terminal phalangeal of the first or second digit of tho 

 pes, not improbably referable to this species ; from Cat's 

 Hole Cavern, Gower, Glamorganshire. 



Presented hij Col. Wood, 1865. 



Family AKDEID.E {siqira, p. 60). 



Genus ARDEACITES, Haushalter'. 



Known b_T the humerus, which indicates a bird closely allied to, if not 

 generically identical, with Ardea. 



Ardeacites molassicus, Haushalter '. 

 The type and only described species. 

 Hab. Europe (Germany). 

 From the Middle Miocene of Algauer, between Augsbourg and Landau. 



Proherodius oweni (supra, p. 60). 

 A. 225. Cast of a right tarso-metatarsus probably referable to this 

 species. The original (fig. 75) was obtained from the 

 London Clay near St. James' Park, and is in the 

 possession of W. J. L. Abbott, Esq., of 3 St. Peter's Eoad, 

 Tufnell Park, }f."W. With the exeeption of the loss of 

 the third and fourth trochleae, the specimen is entire ; its 

 total length being about 0,(J66. It agrees in relative size 

 with the type sternum, and presents many of the essential 

 characters of the corresponding bone of the Ardeidit. 

 Thus the shaft is similarly flattened from front to back, 

 with the well-marked anterior groove confined to the 

 upper part, and the same general contour of the ridges on 

 all the surfaces, and similar muscular depressions on 

 either side of the talon. The three trochleae were evi- 

 dently transversely expanded in the Ardeine manner, the 

 position of the foramen between the third and fourth 

 being precisely the same as in existing forms ; the second
