Mr. H. J. Pearson exhibited some eggs of Larus argen- 

 tatus from Northern Norway, suffused and blotched with 

 salmon-pink or reddish buff, and also some o£ a pale blue 

 colour. Specimens of the former character had previously 

 been ascribed to the Great Black-backed Gull and to the 

 Glaucous Gull, but the authenticity of the present examples 

 was beyond question. Discussion followed on the cause, 

 and allusion was made to reddish eggs of the Raven and 

 other birds. 



Mr. E. BiDWELL exhibited abnormal eggs of Vanellus 

 cristatus and other species.

 Pigeon from the island of Sumba, or Sandalwood, which 

 he described as follows : —

 upper wing-coverts — dark olive, washed with green in some 

 lights and with dark bluish purple in others. Wing dark
