32384. Cast of tlie imperfect left tibio-tarsus, with part of tlic 

 proximal extremity wanting, the portion below this 

 crushed, and the distal end imperfect. This specimen, 

 wliich was obtained at ileudon within a short distance of 

 the preceding, is the second type. It is figured by ^Milne- 

 Edwards, op. cit. pi. xxviii., and also by Owen in the 

 ' Quart. Journ. Geol. Soc' vol. xii. pi. iii. fig. 1 ; and is 

 preserved in the Museum at Paris. 



Presented b;/ Monsieur Hebert, 1856. 



Gastornis klaasseni, E. T. Newton \ 

 In the tibio-tarsus the shaft is proportionately more slender than 

 in the type species, the entocondj-le projects more inwardly, the 

 posterior aspect of the distal extremity of the shaft is narrower and 

 less flattened, the extensor bridge is nearer the inner border, and 

 there is a well-marked groove for the tendon of the peroneus muscle.

A. 86. Cast of the imperfect right tibio-tarsus, wanting the prox- 

 imal extremity. The original, which is one of the types, 

 and is preserved in the Museum of Practical Geology, 

 Jermvn Street, was obtained from the "Woolwich beds 

 (Lower Eocene) of Park Hill, Croydon, Surrey. It is 

 described and figured by E. T. Newton in the ' Trans. 

 Zool. Soc' vol. xii. p. 1-4G, pi. xxviii. figs. 1-3. 



Made in ihe Museum. 



A. 86 a. The distal extremity of the left tibio-tarsus of a larger 

 individual. The original is one of the types, and is pre- 

 served in the Museum of Practical Geology ; it was 

 obtained at Park Hill, and is figured by E. T. Newton, 

 op. cit. figs. T-11. Made in the Museum. 



Gastornis edwardsi, Lemoine^. 



The tibio-tarsus is relatively shorter and stouter than in G. Haasseni, the 

 outer border has a distinct double curvature, the extensor bridge is more distant 

 from the inner border, and the entocondjle projects less inwardly. In the 

 femur the trochanter projects more beyond the outer contour of the shaft, and 

 the anterior crest appears to be less prominent than in the species last named.
