shot meant to make a meal of the egg shown, and that it was 

 not her own egg. We shall await further evidence on this 

 subject with very keen interest, and doubtless Sir Percy Cox 

 will leave nothing undone which may help to elucidate it. 



" Eggs are shown of Chettusia leucura and of Sarcogrammus 

 i. aigneri, common birds but very rare eggs in collections. 

 Sand-Grouse are represented by the rare eggs of Pterocles 

 senegallus and an exceptionally beautiful clutch of P. alchata 

 caudacuta. 



" Raptores are represented by Circus ceruginosus, and there 

 is a fine clutch of Otus scops hrucei. 



" Among the smaller eggs are those of Hypocolius ampelimis 

 and others which are but little known. 



" In regard to the above eggs, I should note that in each case 

 the parent bird was shot, a fact which greatly enhances the 

 value of this collection. The eggs are most generously 

 being given by the collectors to be divided between the 

 British Museum, the Bombay Natural History Museum, and 

 ray self. ^^ 



Dr. C. B. TiCEHURST exhibited the following specimens of 

 young in down : — 



Phaeton indicus. Young in partial down, young fully 

 feathered, and adult. (On behalf of Sir Percy Cox and 

 Major Cheesman.) 



These were obtained on an islet 3 miles W. of Tanb Is., 

 eastern end of Persian Gulf, on April 5, 1921. The young 

 in down seeems to be unknown, and is evidently well covered 

 with greyish- white down, darker grey on the occiput. The 

 fully feathered young, curiously enough, is precisely like the 

 adult, except that the central tail-feathers are short and 

 tipped with black. It is rare in any genus to find the first 

 feather plumage precisely like that of the adult, though it is 

 seen in some of the Petrels etc.
