236 EELIQUI^E AQTJTTANKLE. 



we know that individuals of this species inhabiting Sweden and Lapland are gene- 

 rally of a larger size than those of the temperate regions of Europe ; Brehm has 

 even described them under the name of Nucifraga brachyrhyncha. They have 

 the beak stronger and more arched, and the feet more robust. It is possible that 

 in the Reindeer Period the Nutcracker in France had the characters of those 

 which now live in Scandinavia and appear to constitute a well-defined local race. 



25. THE MAGPIE. Corvus pica, Linne" ; Pica caudata, Linne. La Pie. 



The bones of this species are not met with in the most ancient Stations of the 

 Aquitanian region ; they have been found only at Lacombe-Tayac and Gourdan, 

 and even there are very rare ; I have seen only two humeri. 



26. THE CROSSBILL. Loxia curvirostra, Linne". Le Bee croise. 



A humerus, a coracoid, and a tibia, probably belonging to the same individual, 

 have been collected at Massat (Ariege). This Loxia is at the present day very 

 common in the north of Europe, and even in Greenland, but it is a bird of passage 

 in France. 



27. THE GREENFINCH. Loxia chloris, L. ; Ligurinus chloris, Koch. Le Verdier. 



I have pointed out the existence of this species in the Gourdan Cave ; but 

 M. Piette, who had extracted it, has informed me that he found it in a fissure of 

 the rock at a depth of only 70 centimetres (2 feet 7'5 inches); and its state of 

 preservation made me doubtful of its antiquity. 



28. THE SNOW-FINCH. Fringilla nivalis, Brisson ; Montifringilla nivalis, Brehm. 

 La Niverolle des neiges. 



The Stations of Bruniquel and Massat contain remains which I regard as 

 appertaining to this species ; they consist of a humerus, a tibia, and a foot-bone. 

 It is interesting to find the Snow-Finch in the beds where Lagopodes also 

 abound; for in the present day it lives on lofty mountains together with the 

 latter, in the vicinity of the snow, and only accidentally makes its appearance in 

 the centre and south of France at a distance from the chain of the Pyrenees. 



29. THE SKY-LARK. Alauda arvensis, Linne". L'Alouette des champs. 

 A humerus found in the Station of Le Moustier belongs to this species. 



30. THE MISTLETOE.THRTJSH. Turdus viscivorus, Linne. La Draine. 



This Bird, the existence of which in the Cave at Verezzi, Liguria, I have
