54 Dr. O. FinsclPs Ornithological Letters. 
A. aquaticus, Alpine Crows, apparently Pyrrhocorax , Aquila 
fulva, Saxicola cenanthe (but with a stouter bill), and, strangely 
enough, Crex pratensis. 
The Marakul lake abounded with birds. I never before 
saw so many Eagles; and the number of Milvus melanotis was 
astonishing : on a single dead tree I counted fifteen. The 
Eagles belonged to H. leucoryphus , a species like Aquila ra- 
pax , but larger, A. imperialis, and A. fulva. I shot a singular 
Regulus , without a stripe on the crown, which may be new. 
Besides these we obtained Motacilla citreola, Anthuspratensis , 
Turdus atrogularis, Sturnus vulgaris, and a beautiful Bunting 
resembling Emberiza pithyornis , but different, and perhaps 
new. The lake was rich with waterfowl— Anas rutila (with 
young broods), A. crecca, A. penelope, A. strepera, A. acuta , 
A. boschas, A . nyroca , &c., Podiceps cristatus and P. cor - 
nutus, Carbo cormoranus, Lams ridibundus , Sterna fissipes, 
&c. We saw neither Geese nor Pelecans. 
From Altaiskesche Stanitza we travelled as quickly as pos¬ 
sible by way of Serianowsk TJsdkamenogorsk to Barnaul, 
where we arrived on the 22nd of June. During this journey 
we travelled too fast to observe or collect much. Above Se¬ 
rianowsk I saw a peculiar Swift, larger than Cypselus apus , 
but with a white rump. Dr. Brehmhas since been fortunate 
enough to secure a specimen at Salair, on the northern 
Altai, between Barnaul and Tomsk; and I do not doubt that 
the species will prove to be undescribed. When going on 
the river Irtsch, from Werchne Pristan to Kamenogorsk, 
we found a large colony of Hirundo rufula, the only time we 
met with the species during our voyage. 
Near Barnaul we secured Emberiza aureola , which was 
very common, also Larus minutus. 
I hope to find time to send you a further report on the 
birds observed during our voyage on the river Ob. At present 
we have only spent two days on this magnificent stream. I 
can only say that hitherto I have seen comparatively few birds; 
but the river is flooded. The extensive woods which border 
the river doubtless support a large amount of animal life; 
but .we see little from the deck of our steamer.
