456 Mr. D. G. Elliot on the Genus Malimbus. 
the 2nd June, and afterwards met with the species abundantly, 
both on the islands and on the tundra as far as Dvoinik, 
generally in pairs, and never in large flocks, as observed by 
Alston and Harvie Brown on the Dvina (Ibis, 1873, p. 72). 
We obtained several sets of eggs, and found one nest built of 
water-plants on the edge of a pool in the marsh near the Dvoinik 
beacon. This nest was a floating structure, supported by the 
growing water-plants around, a very different one from those 
generally found on the shores of our own Highland lakes. It 
contained one egg of unusually small size, which caused us to 
carefully identify the old bird, which flew repeatedly close 
overhead and afforded us both ample opportunity without the 
necessity of shooting it. We should say, from what we ob¬ 
served of the Black-throated Diver, that it was not so abundant 
a species as at Archangel, though also plentiful in all suitable 
localities. 
In conclusion, we beg to thank those gentlemen, too nu¬ 
merous to mention, to whose kind assistance so much of the 
success of our trip is owing. We cannot, however, refrain 
from especially thanking Count Schuvaloff for the invaluable 
letters of introduction with which he was kind enough to 
furnish us, which enabled us to continue our journey without 
any delay, and ensured us a reception (in a country which 
has probably never been visited by Englishmen for tw r o and 
a half centuries) which we shall always look back upon with 
pleasure and gratitude as long as we live. 
XLIV .—A Review of the Genus Malimbus, Yieillot. 
By D. G. Elliot, F.R.S.E. &c. 
(Plate XIII.) 
The genus Malimbus was first instituted by Yieillot, in his 
( Oiseaux Chanteurs/ for the bird described by Daudin three 
years previously in the f Annales du Museum 9 as Tanagra 
malimbica. Yieillot gave no definition of the genus; and it 
was not generally used by ornithologists. In 1816 he sub¬ 
stituted for Malimbus , in the ' Analyse/ the term Sycobius,
