the S. dactylatra forms^ but the brown-black head and neck 

 and the lancet-shaped feathers on these parts render it easilj 

 distinguishable. 



Sula abbutti is quite a distinct species with the entire 

 wings deep black, the naked throat bright green, and the 

 feet leaden grey. 



The Hon. Walter Rothschild also exhibited 17 varieties 

 of the Common Partridge [Perdix perdix). Six of these 

 were examples of a type of colour-variation common in 

 Russia, having a pale sandy suffusion in place of the 

 brown-grey. One example was of a silver-grey colour, 

 owing to the almost complete elimination of brown 

 pigment. 



Two birds killed in Devonshire in 1860 exhibited a similar 

 phase in the Partridge to that of ^' Synoicus lodoisiee" found, 

 in the Quail and of Sabine's Snipe among the Common Snipe 

 (which were exhibited for comparison, as well as Gallinago 

 huegeli the representative phase in G. aucklandica). 



Two examples were suffused with a sooty-black colour; 

 these two specimens, from Tring, were examples of a strain 

 of Partridge, now extinct, which had been killed in numbers 

 on two farms near Tring for 10 years in succession. 



Six skins represented specimens of the red phase in the 

 so-called Mountain Partridge (P. perdix ab. montand). One 

 was a complete, and two were almost complete examples of 

 P. montana, while the other three were intermediate between 

 P. montana and typical P. perdix. 



Mr. W. R. Ogilvie-Grant exhibited some remarkable 

 examples of the Red-legged and Common Partridges, showing 

 strange variations in the colour of their plumage, and made 

 the following remarks : — 



" The exhibition of this series of abnormally coloured 

 Partridges was suggested by the recent capture in Kent of a 

 very remarkable Red-leg. It is a second example of the 

 most extraordinary colour-variation known to occur in this 

 species. The first example was killed near Braintree,
