PHASIANID^. 137 



posterior surface docs not present the prominent external ridge 

 found in Perdix, and the shaft is flattened from before backwards. 

 In the type species the humerus is of the slender form found in 

 CoUiniLv ; and, at least in several species, this bone has a deep 

 tricipital fossa, which is but faintly developed in Penlix and 

 Francolimts. 



Palaeortyx hoffmanni (Gervais '). 



Syn. Tringa hoffmanni, Gervais '^. 



The type species. Characterized by the extreme length and straightness of 

 the cranial rostrum. Smaller than Francolinus pondiccrianus, the length of the 

 humerus being 0,039. 



Hab. Europe (France). 



From the Upper Eocene (Lower Oligocene) of Montmartre. 



Palaeortyx blanchardi, Milne-Edwards ^ 



The cranial rostrum is shorter, stouter, and more curved than in 

 the type ; the whole build is more massive, and the dimensions 

 equal to FrancoUnus pondicerianus, the length of the humerus being 

 0,047. 



Hab. Europe (France). 



A. 145. Slab of gypsum showing the dorsal aspect of the imper- 

 fect right humerus ; from the Upiier Eocene (Lower Oligo- 

 cene) of Montmartre. The greater part of the dorsal side 

 of the shaft is broken away. The specimen accords with 

 the humeri figured by Milne-Edwards in his ' Oiseaux 

 Eossiles de la Prance," pi. cxxvi. figs. 3, 4. No history. 



Palaeortyx gallica, Milne-Edwards \ 



Of somewhat larger size than the type species, the length of the 

 humerus being 0,042, and that of the ulna 0,043. 

 If(d). Europe (Erance). 

 Typically from the Lower Miocene (Upper Oligocene) of AUier. 



A. 137. A right coracoid, imperfect distally, which would agree 

 {Fiy.) approximately in relative size with the humerus of this 



species ; from the Phosphorites of Caylux (Tarn-et- 



Garonne). Figured in woodcut 33.
