DESCRIPTIONS OF NESTS AND EGGS. 
Chloromunia trichroa (Kittlitz). GREEN-BACKED FINCH. 
Chlobomunia tbichroa Mathews, Birds Austr., Vol. XXI., pt. v., p. 208, Nov. 23rd, 1925. 
Nest. Large, rounded and loosely constructed. 
Eggs. Clutch five to seven, wide-pointed, oval-shaped. Pure white with no gloss 17-18 mm 
by 12-13. 
Breeding-season. June. 
Littlera chrysoptera. 
Mathews, Birds Austr., Vol. VIII., pt. 2, pi. 378, June 17th, 1920. 
Muscicapa chrysoptera Quoy et Gaimard, Voy. de PAstrol., Vol. I., p. 177 (pi. 4, fig. 2, pref. 
June 29th), 1830 : Hobart, Tasmania. 
At the above quotation, Quoy et Gaimard described this bird. Discussing the 
tail, they say “ et les deux pennes externes sont blanches dans la moitie de leur 
longueur.” The plate also agrees with this. 
Does this not apply only to the Flame-breastecl Robin ? In the Pink¬ 
breasted Robin the outer pair of tail-feathers are paler in colour, but not white. 
If this is true, we must revert to the synonymy as used in my Birds of Australia, 
leaving my tasmanica a synonym of chrysoptera. 
Squatarola squatarola (Linne). GREY PLOVER. 
In the Auk for January, 1930, pp. 79 and 80, Mr. L. L. Snyder points out the 
difference in the sexes of this species in full breeding plumage. 
The female differs from the male in having the black of the under-surface 
not so extensive, and of not such an intense, deep black ; this colour also lacks 
the metallic lustre. On the upper-surface also the females are not so white 
on the head, with the contrasting black and white on the back not so marked ; 
the females never acquiring a completely black breast. 
The males are whiter on the head and have more contrasting black and 
white markings on the back, less of the grey characteristic of winter plumage. 
The feathers are intensely black with a metallic lustre, while the dark feathers 
of the females are brownish-black. This difference is best exhibited in fresh 
skins. 
In the matter of age, it may be stated that there appears to be at present 
no way to separate with certainty birds in their first year from older ones. 
Females, particularly young individuals, retain considerable of then winter 
feathers.
