surface is suffused with brown, especially on the head, and the tail is browner. There is also more 
white on the belly than in the male, and the flank-feathers are white with ashy margins. In winter 
plumage the females are much browner than the males, and the pectoral collar is very indistinct. 
Young males appear to resemble the females, but are darker and more slaty-grey, and the black 
collar on the fore-neck is gradually assumed ; in specimens after the first autumn moult it is often 
interrupted and consists only of black crescentic markings. 
The question whether Geocichla nevia has spotted young or not appears to be at present 
undecided. Professor Elliott Coues (B. Colorado Valley, р. 15) writes :— The young are like the 
adult female. Upper parts in many cases with a decided umber-brown wash. Хо speckled stage, 
like that of the very young Robin, has been observed, though August specimens have been examined. 
In the young male the black pectoral bar is at first indicated by interrupted blackish crescents on 
individual feathers. Young females sometimes show scarcely a trace of the collar. At all ages the 
markings of the head and wings are much the same.” Оп the other hand, Dr. Stejneger (Proc. U.S. 
Nat. Mus. v. p. 466) observes :—“ It is only apparently, as this statement seems to indicate, that the 
young bird is not speckled at all, thus differing from all the other Thrushes, and wanting the most 
essential character. I have now before me a specimen (U.S. Nat. Mus. no. 45897 : Sitka, August, 
1866) which differs considerably from the adult female. Тһе under surface is of a much duller 
colour, without white on the belly and under tail-coverts. АП the feathers of the chin, throat, and 
upper breast have well-marked blackish edges, giving these parts a scaly appearance. In the adult 
female the feathers forming the collar are almost uniformly dark, the edges, if any, being lighter, 
while the feathers of the above-mentioned parts in the young bird are grey and downy on their basal 
half, then ochraceous yellow and, finally, narrowly edged with blackish. Тһе feathers of the upper 
parts of the young bird have no light centres as usual among the Thrushes, except on the sides of 
the neck and on the head, where the middle of the feathers are more or less conspicuously marked 
with a lighter spot. Finally we have a very striking difference between the adult and the young, 
showing the common Thrush-like feature of the plumage of the latter, the smaller wing-coverts 
having wedge-shaped, rusty spots towards the tip and dark edgings, while in the adult bird they are 
absolutely uniform in colour. It will thus be seen that the speckled stage is not altogether wanting 
in this genus, although it may be admitted that it is not so conspicuous as in the young of 
M. migratoria. This fact seems to me to strengthen my view that the present bird, notwithstanding 
a certain resemblance of the predominating colours and their tone, is widely remote from the last- 
named species, in the neighbourhood of which it has been placed by many authors."

The figures in the Plate represent an adult male in the Seebohm Collection obtained in the 
Greenwood Valley in Eldorado County by Mr. A. Forrer on the 17th of December, and a female 
procured by the same collector in the same locality on the 28th of the same month. Тһе male is 
figured of the size of life, and the female a little smaller. [R. B. 5.] |
