swampy ground prevail; such localities are also occupied by 
Motacilla citreola, which we observed after leaving Tachty, a 
few stations below Obdorsk, and Gallinago media. As we de¬ 
scended the river the larger it became, the banks being some¬ 
times out of sight. Waterfowl increased in number. Just 
before reaching Obdorsk we found a small colony of Larus 
marinus breeding. The Polu'i river, on which Obdorsk is 
situated, swarmed with Ducks, among them CEdemia nigra and 
(E. fusca; Colymbus septentrionalis was also very common. 
After having engaged five men, furnished with provisions, 
we left Obdorsk on the morning of the 16th of July, bound 
for the Schtschutschja river, which we intended to ascend as 
far as possible, and thence to the Podarata river and the Kara 
Bay, these parts, lying between the Ob river and the Ural 
Mountains, never having been before visited by any zoologist. 
We reached Janburri, an Ostiakian yurt-place to the east 
of the mouth of the Schtschutschja river, on the 18th of July, 
and with difficulty obtained two Samojeds to act as pilots up 
the river, as no one was acquainted with this part of the 
country, which is only visited by nomad Ostiaks and Samo¬ 
jeds and their herds of Reindeer. At Kiocliat, a fishing- 
place on the right bank of the Ob, Larus marinus was plen¬ 
tiful, engaged in stealing fish from the nets. I here ob¬ 
served their singular habit of perching on dead branches of 
high trees. As soon as we reached the left bank we came to 
low flooded land, cut into many silent channels, bordered 
with low willow-scrub. Here Motacilla citreola was not 
uncommon, as also even Phalaropus cinereus. At Janburri 
Dr. Brehm shot Anthus seebohmi, discovered last year by Mr. 
Seebohm on the Petchora river, and of which new species I 
had been kindly provided with a description by my friend Mr. 
Dresser. A little above Janburri I got a species of Calamo- 
herpe , peculiar in its manner and song, the latter being very 
sweet. As soon as we entered the Schtschutschja river we 
came into the tundra-region, except on the right bank, which 
is still covered more or less with woods. We observed Otus 
brachyotus and, for the first time, Lagopus albus, not yet in 
full summer plumage. Tot anus glareola was the most com-
