Meetings of Section I. 41 



He also exhibited photographs and a map showing- its 

 exact distribution. 



He stated that this form was only found on the higher 

 pasture land of the Pyrenees at an elevation of about 2000 

 metres. 



It was said to differ from typical P. perdrix in having 

 the plumage of the neck and breast more spotted, the wing- 

 coverts in the male transversely barred with buff like those 

 of the female, and the horseshoe-mark on the breast of a 

 very dark chestnut colour. 



Dr. Reichenow stated that this was the Partridge he had 

 described as Perdix hispaniensis (J.F.O. 1892, p. 226), and 

 that his name had priority over P. charrekc, Seoane (1894), 

 as had been explained by Mr. C. D. Sherborne, [cf. Ann. 

 and Mag.N.H. (6), xiv., p. 154 (1894).] 



Mr. W. Ogilvie-Grant said that if the marking of the 

 wing-coverts was really alike in both sexes, it was no doubt 

 an important character, but that a series of specimens, in 

 which the sex had been carefully ascertained, was still 

 required to prove this. He did not consider the darker 

 colour of the horseshoe mark on the breast of much value, 

 as it varied in typical examples of P. perdix. Both the birds 

 exhibited by Dr. Bureau were immature, as was shown by the 

 pointed first primary quill. 



The Hon. Walter Rothschild said that Partridges pro- 

 cured in England were of no use for the purpose of studying 

 different races, as birds from all parts of Europe had been 

 imported, and had interbred freely with our native birds. 



10. Dr. J. Dwight : The Significance of Sequence in 

 Moults and Plumages. 



Dr. Dwight, after stating that feather-growth, plumag*e- 

 development, and plumage-renewal are founded on sequences, 

 explained this sequence in plumages and moults, and urged 

 the use of terms by which the plumage-cycle of any species 

 of bird may be definitely expressed. 



There were three distinct stages of plumage recognizable, 

 that of the nestling, that of the young bird, and that of 

 the adult, for which the names natal, juvenal, and adult were
