Calidris tenuirostris Schaanning, Ibis, 1929, Jan. : Kolyma district, N.E. Siberia (eggs described : 
cf. Emu, Vol. XXVIII., p. 299, April, 1929); Leonidas Portenko, Artica, 1933, No. 1, 
Nov., pp. 75-98. 
The chick is described by Portenko for the first time. I quote the following 
from his Article :— 
It will be remembered that the eggs were discovered in the Kolyma 
Mountain as described by Schaanning. They were laid on a barren mountain 
1,500 feet above sea-level, the nest being a slight depression in short reindeer 
moss. 
The breeding locality has now been extended further east, to the Anadyr 
River, where the downy young have been discovered, as described by Portenko. 
One adult specimen was taken on a flat summit of one of the off-shoots of Mount 
Terpukhov which descends, step-like, down to the Anadyr River at a distance 
of about three miles, and about half a mile from the upper limit of a larch forest. 
Mount Terpukhov is situated near the Settlement Yeropol and its highest point is 
about 3,540 feet. The actual place where the bird was taken was characterized 
by separate rounded lulls, with gently descending slopes. On the sides of these 
slopes the creeping cedar bushes were replaced by single, close-to-the-ground- 
lying specimens not above a foot in height. The ground in this locality 
consisted of blackish-grey small fragments of rocks, covered by a thin crust of 
lichens, with separate clumps of low-growing herbs about two to three and a half 
inches deep. 
At the end of May, 1932, in the Alpine zone of Mount Terpukhoy, spring 
thawing had set in and there showed places free from snow. At the above- 
described type of country there were observed recently arrived small flocks of 
these birds, which flew from one thawed-out spot to the other, picking up 
something on the rocky debris, and they did not show any shyness. Later, 
on the journey up the Anadyr River and some of its affluents, the birds were 
not met with on similar country ; this t}’pe of country proved to be characteristic 
of, and peculiar to, the whole mountain region in the basin of the upper reaches 
of the Anadyr River. Their absence may be explained by the fact that the
