France, Finland, and Roumania, not selected in any wa)^, 

 but all considerably below the avei-age size of British eggs, 

 A series of eggs of Charadrius duhius ciironiciis from such 

 widely-separated localities as France, Spain, Germany, 

 Central Asia, and Japan, showed little variation, but the 

 eggs of C. dubius jerdoni from southern India, of which 

 Mr. Stuart Baker showed a series, were remarkably different 

 in size and type of markings. Another instance is that of 

 the Mediterranean form o{ Puffinus kuhli,vi\\\c\i lays a much 

 smaller egg than the Atlantic race of the same species. The 

 above instances are purposely chosen from birds on the 

 British list, but might be indefinitely extended, and the 

 speaker appealed for a closer study of the eggs of the various 

 races of birds, urging that constant distinctions in the eggs 

 were of as great importance as differences in shades of 

 colouring in the adult. 



Mr. E. C. Stuart B.4Ker exhibited some eggs of Tringa 

 guttifer, Armstrong's Sandpiper, and made the following 

 remarks : — 



" The eggs which 1 am exhibiting to-night are, I believe, 

 the first and only eggs ever taken of this rare Wader. The 

 two clutches each of four eggs have been in my possession 

 ever since 1911, when they were most generously given to me 

 by Captain Stein, I. M.S., together with the rest of his most 

 interesting collection of Tibetan eggs. In a letter accom- 

 panying them, Captain Stein said that they were the eggs 

 of a small kind of Greenshank, with yellowish legs, which 

 appeared to breed in company with Redshanks in the 

 marshy laud surrounding the Rhamtso Lake, between 13,000 

 and 14,000 feet elevation. The true Redshank bred there 

 in some numbers, but this bird was rather larger and could 

 be distinguished at a glance by its having yellow-green 

 instead of red legs. Major F. M. Bailey does not appear 

 to have noticed this Sandpiper, but observes that the 

 Greenshank does not breed in Tibet though it passes 

 through in some numbers on migration. 



Although it seemed almost certain tliat the eggs wcie
