dark greyish brown, finely mottled or streaked with rufous and 

 darker brown, some of the spots being of a considerable 

 size. 



[We have examined Mr. Durnford's skin of this species, 

 and find it correctly named. — Edd.]

As common as FJeuco2)i/(/ia,Sinc\ 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 ^. hiaticula in 

 England. 



43. HiMANTOPUs BRAsiLiENsis (Brclim) ; Ibis, 1877, p. 198. 

 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.
