the yelk had a fine reddish-orange colour, while that of 8. Acrwndo was ochreous 
or dull yellow. This afforded a sufficiently distinctive mark on emptying the 
eggs, The number in each clutch was three or four, but many nests as yet 
held but one or two. The general form was a long or short oval, but others 
were spool-shaped, and a few pear-shaped. The ground-colour was pea-green, 
grey-green, olive-green, buff-brown, and grey-brown: a grey-white as in 
S. lirundo I never found, The faint shell-spots were blackish, the larger and 
more conspicuous spots—which were often confluent, sometimes forming a 
wreath at the thick end,—as well as the smaller points, were all black or liver- 
brown. The different nests often held eggs much unlike in form and colour.” 
Herr Meves adds a list of measurexients shewing how they varied in size, and 
remarks that in nowhere else during his journey did he meet with this species, 
and that on his return he revisited Dubno on the 22nd of August, but found 
that all the birds had left the place, which, he elsewhere (p. 753) states, is 
25 versts, or two Swedish miles and a half (about 15 or 16 English miles), from 
Novaja Ladoga. He furnished Mr. Dresser with a statement practically the 
same as the above, with perhaps a few more details, which the latter has 
printed in his ‘ Birds of Europe’ (viii. pp. 378-880). |

The label shews that this, as well as the parent of it (no. 44307), was also 
from Mr. MacFarlane, who writes of this species (Proc. U.S. Nat. Mus. xiv. 
p. 418) :—‘ Thirty-seven nests are recorded as having been taken with eggs 
in them between 10th June and 10th July, in the wooded country in the 
neighborhood of Fort Anderson and on Lower Anderson River; they were all 
built on trees at various heights (from 4 to 15 and even 20 feet) from the 
ground, and, with one exception, which was composed of down and velvety 
leaves held together by some stringy turf, they were made of small sticks and 
twigs lined with hay and mosses, etc. ...... They seldom lay more than 
three eggs.” I exhibited this ege at a meeting of the Zoological Society, 
17 January, 1871, and it was subsequently figured as above. |
