Tool, Tresco, Isles oE Scilly, on September 2nd, 1920, on the 

 exact spot where a Greater Yellow shank, Totanus melano- 

 leums, was shot in September, 1906. The bird, which proved 

 a female by dissection, was observed about the pool for four 

 days before being shot. 



Mr. P. F. BuNYAED exhibited the following eggs : — 



Hooded Ckow {Corvus comix). — Two eggs showing true 

 erythrism from Mark Brandenburg, April 1882. Ground- 

 colour pale pink, with various shades of fine and evenly 

 distributed chocolate-brown surface-markings and purplish- 

 grey underlying markings. Measurements 43x29 and 

 43 X 30 mm. Erythristic comix eggs have been previously 

 recorded from Sweden and Mull. 



Whitethroat {Salvia commums). — An erythristic clutch 

 of six from near Berlin. Ground-colour pinkish-white ; 

 surface-markings pale reddish-brown, suffused and large,, 

 mostly confined to larger axis. Underlying markings, various 

 shades of lead-grey, large and conspicuous. 



Another clutch of five from Mark Brandenburg had 

 ground-colour pale greenish-white, with very bold surface- 

 markings of dark brownish-black. Underlying markings 

 olive-brown, suffused and large. 



Bareed Warbler {Sylvia nisoria). — A clutch of four 

 from Coepenick, near Berlin, 2/7/10, showing true erythrism. 

 Ground-colour very pale pink ; surface-markings absent, as is 

 the case with nearly all nisoria eggs. Underlying markings 

 pale ash-grey tinged pink, mostly confined to the large ends. 



He believed this to be the first recorded occurrence of 

 erythrism in nisoria eggs. 



Black Redstart (Phoenicurus titys). — A clutch of four 

 marked eggs from Coepenick, near Berlin. These are typical, 

 except for the fine markings of pale reddish-brown at the 

 larger ends. 



They arc genuine pigment-markings, some of which are 

 well under the outer lime-layer. '
