Mr. J. Gr. Baker showed and made remarks on specimens of 

 supposed hybrids between the Oxlip (Primula elatior) and the 

 Cowslip (P. veris) from Kew Gardens. 



In illustration of his paper, Lord Walsingham exhibited a large 

 nest containing cocoons, also specimens of the insects and of the 

 Inrvffi of a Congregating Moth of the genus Anaphe, from Natal ; 

 and he also showed alive example of a Dipterous parasite which 

 had emerged from the same.

Mr. W. Brockbank exhibited a series of Double Daffodils, wild 

 ioi'xaii of Narcissus Pseiido-narcissiis, '^\\\c\\ were gathered in a 

 Welsh meadow, both the single and the double forms occurring 

 there in every stage of growth. Sections of these double flowers 

 revealed stamens and pistils ; and in two of the most completely 

 double forms, ovaries filled with seeds were present. With this 

 evidence he therefore contended against the current notion of 

 cultivation and root-growths having produced a heterogeneous 

 multiplication of the perianth-segments, and conversion of 

 stamens into petal-growths, his belief being that the plants in 

 question were propagated in the ordinary way by seed. 



Mr. E. Morton Middleton showed an example of a Jackdaw with 

 such albinism of the scapulars and secondary wing-feathers as to 

 cause considerable resemblance in the bird to a Mag^jie. The 

 Jackdaw had been seen and observed for some time at Castle 

 Eden, Durham, prior to its dying from an injury.
