notice that there seems a constant difference of small amount between 
the individuals of P. eristatus and P. nigripennis now living in the 
collection. In P. nigripennis all the feathers of the posterior row 
of median coverts appear to lap distally. ‘The Common Peacock is

well represented in the particular feature under notice by one of the 
fine pieces of Japanese metal-work at South Kensington already re- 
ferred to under the head of Accipitres. 
In the pterographie characters of both the Hemipodii and the 
Crypturi, I have hitherto failed to discover any marked charac- 
teristic connected with the point under consideration that would serve 
to distinguish these birds from the Gallinze. In the case of the 
Tinamous, especially, the structural characteristics of the palate had 
led me to expect a wing-pattern of a much lower type. 
With the exception of Goura, already noticed, the pterographic 
characters of the Columbe are remarkably uniform throughout. 
These characters are well displayed in the case of the Domestic 
Pigeon (fig. 17). Here it will be noticed that the proportion of 
feathers showing distal overlap, at the proximal end of the median 
coverts, remains much the same as in the Galline ; but that in place 
of the well-marked, uniform, and uninterrupted proximal overlap of
