beautiful series from South Varangar. Among them four 

 clutches of eight, five clutches of seven, and seven clutches 

 of six ; clutches showing very blue ground and those with 

 suffused reddish-brown markings almost concealing the 

 ground-colour were conspicuous. Compared with the eggs 

 of preceding species, they were easily distinguishable in the 

 series. 



Linnet (Acanthis cannahina). A series of twenty-five 

 clutches showing great variation for this species, those with 

 large suffused markings being particularly beautiful ; eggs 

 without markings were represented. 



Holboll's Redpoll (AcantMs I. liolhoelli). A clutch of 

 six well-authenticated eggs from Russian Kola, taken by 

 Helge Lilliestierna. These do not show any characteristics 

 which could separate them from Linarid eggs. 



Lesser Redpoll {Acanthis I. cabaret). A well-repre- 

 sented series showing the type and varieties. Among the 

 latter were some heavily pigmented clutches with the 

 markings mostly confined to the greater axis, and one 

 clutch of five from Lancashire showing dark bluish-green 

 bands. 



Twite [Acanthis fiavirostris) . A series showing the two 

 well-known forms. Those with the vein-like markings 

 are typical Jlavirostris eggs ; those with evenly distributed 

 fine markings are almost undistinguishable from those of 

 cannabina. 



The series of Lesser Redpoll, Twite, Siskin, Linnet, and 

 Goldfinch were shown side by side to demonstrate the 

 difference in the ground-colour of the five species, which 

 is easily distinguishable in a series; the Redpolls^ showing 

 the warmest shade come first, and the other species as 

 placed above. 



Northern Bullfinch (P. pyrrhula). A clutch of six 

 from Dorpat. These do not differ from pileata eggs. 



British Bullfinch (P. p. pileata). A series of twenty- 

 four clutches. Among them a clutch of five pure wliite 

 eggs, slightly marked pale red (Northants), a similar clutch 

 of four (Surrey), a clutch of six white eggs slightly tinged
