fair amount of gloss. I have three clutches in my collec- 

 tion, and as they show a good deal of variation I will describe 

 each one. 



(1) Ground-colour, pale greenish-buff ; round the broad 



end 0£ the eggs a very indistinct, almost obsolete, 

 zone of a slightly darker shade of the same colour. 



(2) Ground-colour, pale drab ; round the broad end of 



the eogs a distinct zone of dark-buff. 



(3) Ground-colour, creamy-buff; round the middle of the 



eggs a broad and very distinct zone consisting of 

 confluent blotches of brown. In this clutch the 

 whole shell is covered with small, almost obsolete, 

 spots of pale greenish-brown. 

 The measurements of the eggs are in inches, "55 to "65 long 

 by '43 to '4(3 broad. 



All Jiests were found in the months of October and 

 November.

 By Percy F. Bunyard, F.Z.S., M.B.O.U.C. 



(Plate II.) 



Very few egos have been more neolected than those of 

 Fraternda arctica. 



In most collections they are generally represented by one 

 or two indifferent specimens, selected for their superficial 

 markings. Those which appear to be unmarked are regarded 

 as uninteresting or wholly unworthy of a place in the 

 cabinet. 



From a strictly oological point of view these apparently 

 unmarked eggs are most interesting, and on a closer exami- 

 nation many of them will be found to be, not only well- 

 marked, but often heavily pigmented. 



To the unaided eye, however, nine-tenths of these mark- 

 ings are invisible, owing to their being very deep-lying. 

 In order to reach this pigment it is necessary to remove, 

 by scraping, the outermost glutinous layer, and also the 

 outer lime layer, before the pigment is reached ; this, as
