dark greyish brown, finely mottled or streaked with rufous and 
darker brown, some of the spots being of a considerable 
size.

and find it correctly named.— Edd.]

As common as F. leucopygia^ and nesting in similar localities. 
Eggs of a stone-grey ground-colour, speckled and streaked 
with dark rufous and black spots; they vary, however, a good 
deal in colour. I have generally found six to be the num¬ 
ber laid.

From having observed this species in October, December, 
and February, I conclude it is a summer visitor, though I 
believe it is the same species that Mr. Hudson calls (P. Z. S. 
1871, p. 261) ^^a pretty little cinereous Plover, with a rufous 
head and belted breast,^^ and which, he says, is also found 
in winter sparsely distributed over the southern half of this 
State.^^ I have always found it on dry sandy ground, 
frequenting the same sort of places as jF. hiaticula in 
England.

On the 24th December, 1876, I found two or three pairs 
nesting near Lujan bridge, and, after lying behind a bank for 
about twenty minutes, watched one old bird onto the nest. 
This was on rough swampy ground, and on a slightly elevated 
spot; it was composed of a few pieces of roots and dry grass, 
which were placed in a slight hollow. It contained four eggs, 
in general appearance similar to those of Vanellus cayennensis, 
but rather longer in proportion to their breadth. The ground¬ 
colour is pale olivaceous, thickly blotched and streaked with 
dark brown and black markings, chiefly at the larger end. 
Both parent birds showed extreme solicitude about their 
nesting-ground being invaded, and endeavoured first to drive 
me away by angry screams, and darting close by my head; 
and finding that useless, one of them feigned lameness.
