 dimensions of Cohimhns septentnonalis. 

 Hah. Europe (England). 



A. 112. Cast of the distal extremity of the left tarso-met a tarsus 

 probal.ly referable to this genus and species. The 

 original, which is in the collection of T. Jesson Esq 

 was obtained from the Cambridge Greensand, and is 

 described and figured by Seeley in the 'Quart. Journ 

 Geol. Soc' vol. xxxii. p. 500, pi. xxvii. figs 24 25 It 

 differs from the corresponding bone of Cohjmhm iu the 

 following points. In Cohjmhus the third trochlea is 

 both wider and longer than the fourth; the posterior 

 surfnces of these trochleoe do not extend nearly so high up 

 in the fossil as iu the recent bone ; the profile of tl.e 

 second trochlea is angulated in the fossil and rounded in 

 the recent bone; and there is no deep depression above 

 the trochleas on the posterior aspect of the former In all 

 these resj,ects the fossil approximates to Baptornis and, 

 m a less degree, to Ilesperoniis.
