east Siberia, Mr. Koren^in the summer of 1911, sailed his 

 schooner through Behring Strait and along the north coast of 

 Siberia to the mouth of the Kolyma River, where larch forest 

 occurs and where he wintered. He set off again in June 21 

 of the following year, but was caught in the ice and wrecked 

 before he reached Behring Straits. He saved most of his 

 collections and " cached " them, got out overland, and return- 

 ing the following spring was able to recover them intact. 

 He must have indeed been a man of uncommon grit. 



The list of birds is a very interesting one and well worthy 

 of study. Although the winter climate was very severe — • 

 85° below zero of Fahrenheit was not uncommon — there were 

 a good many winter birds. Siberian Jay, Raven, HolboU's 

 Redpole, Hawk Owl, Snowy Owl, Short-eared Owl, 

 Gyrfalcon, Tetrao parvii-ostris, and Lagopus lagnpus koreni, 

 the last-named a new subspecies, all seem to be able to 

 exist in this arctic climate. 



It is curious that though Buturlin found a large breeding 

 colony of Ross's Gull [Rhodustethia rosea) at the Kolyma 

 delta in 1905, and although Mr, Koren was informed that 

 these birds were abundant and bred there in 1911, he 

 himself in 1912 was only able to find one stray example 

 of this beautiful Gull. 



Three American species are here added to the list of 

 Palsearctic birds — Pisobia pectoralis, Haliaetus leucocephalus 

 alascanus, and Hylocichla aliciae alicice, while a number of 

 new subspecies are proposed : Lagopus lagopus koreni, Circus 

 cyaneus cernuus, Budytes fluvus plexus, and Otocorys 

 alpestris euroa. 



Walpole-Bond on rare British Birds. 



[Field-studies of soma Rarer British Birds, by John Walpole-Bond. 

 Pp. ix+335. London (Witherby), 8vo. 7s. 6«?.] 



Mr. Walpole-Bond here gives us an account of his own field- 

 studies of what he considers to be ''some rarer British birds," 

 although why he includes the Short-eared Owl iu this category 

 is not easy to explain. The following seventeen species 

 are discussed under this heading : — (1) Dartford Warbler ; 

 (2) Pied Flycatcher; (3) Cross-bills in Sussex; (4) Girl
