New Zealand Certhiparus. As might, therefore, be antici- 

 pated, the species and subspecies of former authors arc 

 placed on an equal footing, while the forms to which tri- 

 nomials ar,e now applied are those barely to be recognised 

 as distinct. A more misleading method can hardly be 

 imagined, though we are aware that the author is only 

 following other writers. Many well-known appellations are 

 changed, scarcely for the better, and three new races are 

 named, of which Pardaliparus potanince from Kan-su alone 

 need be mentioned. But, though we cannot agree with the 

 treatmeut of the family, the list is a careful piece of work, 

 which will serve as a useful resume of the subject. Two or 

 three more forms have since been described.

We have here an account of the birds collected during 

 the Russian Scientific Expeditions sent to Spitsbergen in 1899 

 and the following years for the purpose of measuring an arc 

 of the horizon. Most of the zoological work was done by 

 Dr. A. A. Bunge, who passed the whole winter of 1899-1900 

 in Spitsbergen ; he contributes a most interesting diary of 

 the departure of the last birds of each species in the autumn 

 of 1899, and of their earliest arrival in the following spring. 

 Other members of the expedition who took part in the 

 collecting and observation of birds were Herr A. A. Bialy- 

 nicki-Birula, Dr. A. Wolkowitsh, Herr Michailowski, and 

 Herr Backlund. Twenty-four species are registered as 

 having been met with, and good field-notes are added con- 

 cerning them. Amongst them is the Redwing (Turdus 

 tlmcus), of which a single stray individual was captured alive 

 in October 1899. 



At the end of the paper is given a complete list of the 

 birds that have as yet been recorded from Spitsbergen and 

 Bear Island — fortv-six in all besides three which are
