eggs, goldfinch (Surrey), goldcrest and wood wrens (New Forest), 

 various warblers, &c , vcere most interesting, whilst the different 

 clutches of the red-backed siirike showed great variety, not only in 

 the different clutches of eggs but also in the materials used for nest 

 making. It is most interesting to find a collection of birds' eggs with 

 the variation worked out in a scientific manner. 



CoLiAS EDUSA. — It may interest tlie readers of the " Britisli 

 Naturalist" to know that tvv^o specnnens of this butterfly were 

 observed here on May 26th. My father and my sister each saw one.— 

 Herbert x\shby, Southampton. 



Variety of -\rctl\ mendica. — Mr. Lumsden, of this town, has 

 bred a very curious variety of the female of this species. The fore 

 wings are cream coloured, with two black spots on the median 

 nervure, the hue being decidedly deeper than that of the males of the 

 Irish variety. The hind wings are of the usual dead white, with two 

 small spots near the hind margin, and contrast very strikingly with 

 the fore wings. Mr. Lumsden has, with the greatest kindness, 

 presented me with the specimen. — John E. Robson, Hartlepool.
