THE BIRDS OF AUSTRALIA. 
Latham’s : 
“ S(ylvia) lateralis. S. griseo-ceeruleseens subtus albida, alis uropygio 
recticibusque lateralibus viridibus, loris nigris Rusty-sided Warbler, 
Gen. Syn. Sup. II., p. 250, 38. 
Habitat in Nova Hollandia, parva species magnitudine Troglodytis latera 
corporis ferruginea. 
“ Rusty-sided W(arbler). Size of a Wren ; bill dusky; legs pale; the 
greater part of the head and wings, lower part of the back, and all 
except the two middle tail-feathers green ; hind part of the neck, the 
beginning of the back, and the two middle tail-feathers blue-grey; 
under-parts of the body whitish, but the sides of it are ferruginous; 
between the bill and eye a narrow streak of black. Found with the 
last (New South Wales).’ 1 
This is an excellent account. 
Quoy and Gaimard named and figured a bird from Western Port, 
Victoria, just a little later than Vigors and Horsfield had introduced their 
genus Zoster ops. Vigors and Horsfield’s description reads: 
“ Dorsalis. Zost. flavescenti-viridis, dorso cinereo, striga ante subtusque 
oculos nigra; subtus flavescenti-albidus, gutture pallide flavo, abdominis 
lateribus ferrugineo tinctis. Remiges rectricesque fuse®, flavescenti-olivaceo 
marginatse, subtus pallidiores. Tectrices alarum inferiores albidae. Orbitae 
plumulis albis vestitae. Rostrum pedesque flavescenti-fusci. Longitudo 
corporis, 4f ; alee a carpo ad remigen tertian, 2 T ^; caudae l^j; rostri ad 
frontem, f; ad rictum, ; tarsi J. Mr. Caley has not noticed the habits of 
this bird, beyond its having built its nest in a mulberry tree close to his house.” 
Quoy et Gaimard’s description reads: “ Daenis, rostro conico, acutissimo; 
palpebris albis ; gula genisque flavis ; capite uropygio et alis virescentibus; 
dorso cinereo; abdomine flavo.” 
I have reprinted this description as it may prove important as the first 
description of the yellow-throated bird which Sharpe separated as a distinct 
species under the name Z. westernensis Q. and G., which was published three 
years later. T his is the more strange as the type of Vigors and Horsfield’s 
Z. dorsalis is in the British Museum. Quoy and Gaimard’s figure appears 
to have been drawn from a young bird and much over coloured. 
Sharpe used ccerulescens for the white-throated form and westernensis 
for the yellow-throated one, regarding them as distinct species, and Hartert 
so accepted them. North, however, collected a series in the neighbourhood 
of Sydney which he contended proved that the yellow-tlnoated form was 
only the spring and summer plumage of the white-throated one. North’s 
conclusions were accepted by Australians and I have followed tliis usage, but
