194 Mr. H. Seebohm on the Ornithology of Siberia. 



CALIDRIS ARENARIA (Linn.). 



Numerous flocks of this species were seen by the Swedish 

 Expedition of 1875 at the mouth of the Yen-e-say'. 



TRINGA TEMMINCKI, Leisl. 



This species was first met with by Dr. Theel on the 22nd 

 of July, in lat. 65^, which probably represents the southern 

 limit of its breeding-range. 



ANAS BOSCHAS, Linn. 



Dr. Theel observed the Mallard up to lat. 60. 



FULIGULA CRISTATA (Leach) . 



Dr. Theel shot a Tufted Duck in lat. 68. 



(EDEMIA FUSCA (Linn.). 



Dr. Theel observed the Velvet Scoter in lat. 69 and 69i- 



STERNA LONGIPENNIS, Nordm. 



Dr. Theel obtained a Tern in lat. 63, which Mr. Meves 

 has identified as belonging to this species. 



In my first paper on the ornithology of Siberia, I fear that 

 I scarcely did justice to Prjevalsky. It appears that I was 

 misinformed as to the scientific knowledge of ornithology 

 possessed by this great traveller. His fame as an explorer of 

 almost unknown districts of Central Asia, however, is so 

 great that it almost obscures the fact that he has added very 

 largely to our knowledge of the ornithology of that interesting 

 region. 



I may also take this opportunity of expressing my pro- 

 found regret at the untimely death of my friend, Valerian 

 von Russow. He had been engaged for some months in an 

 ornithological expedition in Turkestan. Just before his 

 return home I had a letter from him, dated Samarcand, 

 telling me of his success ; the next intelligence I received 

 was that he had died of smallpox within a week of his arrival 

 in St. Petersburg. In Russow ornithology has lost an 

 enthusiastic field-naturalist, who was rapidly acquiring the 

 scientific knowledge of birds which can only be attained 

 where large series of skins are available for comparison.
