Five examples were procured by Mr. R. B. Woosnam and

Mr. Ogilvie-Grant exhibited a series of examples of the 

 Red Grouse {Lagopus scoticus), both male and female, killed 

 dui'ing every month of the year ; and he also showed, for the

 from March to August and in autumn-winter-plumage from 

 August to March. 



Mr. Ogilvie-Grant said that, in company with Mr. Pycraft,

 individuals one or two new feathers of the autumn-plumage
