76*0 mm., and 76'5 by 62 mm. The series also contained 

 eggs of remarkably deep coloration. 



He also exhibited a series of eggs showing erythristic 

 variation. The first group contained eggs which are so 

 often of a red type that they could almost be considered a 

 normal variation, such as Sterna bergii, Pyctorhis sinensis, 

 Dendrocitta, and Urucissa, whilst the second contained 

 eggs of which red varieties are extremely rare, such as 

 Sarciophorus, Corvus splendens, and Dumetia. 



Mr. G. WiTHERiNGTON exhibited a remarkably fine series 

 of eggs of the common Merlin (Falco asalon), together with 

 a few selected clutches of the Kestrel {Falco tinnunculus), to

 {Falco peregrinus peregrinus) .

 single eggs of the Lapwing and Redshank, mostly from 

 Kent and Sussex. Some extraordinary varieties were among 

 these. Also a series of Black Guillemots' eggs taken 

 in the British Isles, including some very finely marked 

 specimens. 



Mr. R. H. Read exhibited a very large and beautifully

Also a series of clutches of white eggs of the following 

 species : — Spotted Flycatcher, Bullfinch, Sedge- Warbler, 

 Garden-Warbler, Lesser Whitethroat, Reed-Bunting, and 

 Skylark. Mr. Read also showed a number of rare and
