950 LPECLRIGES, 
consisting of only one row of feathers, which in the case of the 
Greater agrees in number with that of the Remiges, each tectrix 
being placed on the proximal side of its corresponding remex. 
When the 11th or terminal quill is absent its Upper covert remains 
as a supernumerary, as for instance the well-known stiff ‘ painter’s 
feather” of the Woodcock. The Lower 11th tectrix is less constant, 
and in the Gallinw, for example, is absent. Similar conditions are 
found in the 10th Greater covert of many Pusseres, and sometimes 
STERNA. PLotus. 
C, supplementary ; D, posterior row of Middle Upper wing coverts ; x shews the point of 
change in the overlap. (After Goodchild.) 
(From the Proceedings of the Zoological Society, 1886.) 
the terminal Upper covert is even larger than the corresponding 
quill. The Upper covert of the first or proximal digital (“ primary ”) 
quill is often very small or even absent, being completely overlaid 
or represented by the corresponding Middle covert, an arrangement 
probably produced by the mechanical conditions necessary to the 
folding of the wing. The Upper Greater coverts of the cubital 
(‘secondary ”) quills likewise grow from the proximal side of their 
remiges, but they cross the latter in an outward direction. The 
Lower tectrices are also inserted proximally, but those of the Greater 
series do not cross their remiges, though they are crossed inwards
