44 THE ZOOLOGIST. 



interesting species of birds (some, like the Eock Ptarmigan, not 

 known to occur in Eastern Siberia), and found the nests and 

 eggs of others, like the Little Bunting and Mountain Accentor, 

 hitherto undescribed. Amongst the characteristic birds of this 

 part of the world are the Fieldfare, the Siberian Chiffchaff and 

 Stonechat, the Dusky Ouzel (Merulafuscata), the Siberian Ground 

 Thrush (Geocichla ribiiica), the Lapland Bunting, Little Bunting, 

 Ruby-throated Warbler, Waxwing, Pine Grosbeak, Nutcracker, 

 Three-toed Woodpecker, Willow Grouse, Golden Plover, Great 

 Snipe, and Pin-tailed Snipe. 



The interbreeding of the Carrion Crow with the Hooded Crow 

 had never been noticed on such a large scale as observed by 

 Mr. Seebohm, nor had the fact that the hybrids between these two 

 species are fertile been satisfactorily ascertained. Mr. Seebohm 

 obtained specimens of these hybrids in various stages, showing 

 in different proportions their relationship to both parents. 



Through the kindness of Mr. Murray, we are enabled to pro- 

 duce here Mr. C. Whymper's illustration of these birds (given at 

 p. 288), as well as the cbaracteristic sketch by the same artist of 

 the Beindeer sledge (p. 01), and that interesting monument to the 

 traveller, the Boundary Stone between Europe and Asia (p. 11). 



Amongst the characteristic mammals of which Mr. Seebohm 

 saw specimens or procured the skins, were Bears (six roubles the 

 skin), Ermine (ten to fifteen kopeks a skin), Grey Squirrel (same 

 price). The Striped Squirrel (common to both Asia and America) 

 and the Siberian Marten were occasionally offered by the peasants 

 for fifty kopeks to a rouble each. Two skins of the Glutton were 

 bought, one for four the other for five roubles. Otter and Blue 

 Fox {Vulpes lagopvs) were offered at ten to twelve roubles; the 

 latter, in its white winter garb, at three to five roubles. Mr. 

 Seebohm made many inquiries for skins of the Sable (which is 

 only found in Siberia) and the Black Fox (a melanistic form of 

 (J\ vulgaris), but never succeeded in seeing any, they being 

 reserved probably for the Yenesaisk merchants, who would give 

 twenty-five roubles for a Black Sable, and double that price for a 

 Black Fox. The Beaver, it appears, has been extinct on the 

 Yenesay for many years. 



It was unfortunate that, having travelled so far, Mr. Seebohm 

 was prevented from reaching the coast, and investigating the 

 bird-life on the Kara Sea. He considers also that he would
