95. Feilden on the Birds of Novaya Zemlya. 



[A Polar Reconnaissance, being the Voyage of the ' Isbjorn ' to Novaya 

 Zemlya in 1879. By Albert H. Markbam, F.R.G.S. London : C. Kegan 

 Paul ife Co., 1881. Note on the Birds collected by Captain A. H. Mark- 

 ham, R.N. By Captain H. W. Feilden, F.G .S., C.M.Z.S.] 



Captain Feilden contributes to Capt. Markham^s interesting 

 narrative of his ' Polar Reconnaissance ' of 1879 an account 

 of the ornithological collection, ''consisting of some sixty 

 Avell-preserved bird's skins, comprising 26 different species.'* 

 Notes on their distribution, derived from observations made 

 by Capt. Markham, are added. Captain Feilden then gives 

 a very useful account of our previous authorities on the 

 Birds of Novaya Zemlya, and concludes with " A list of the 

 Avifauna of Novaya Zemlya and Waigats,'' deduced from these 

 sources and from Capt. Markham's collection. 



The list comprehends 45 species — amongst which are six 

 Passeres — three of which {Anthus cervinus, Plectrophanes 

 nivalis, and Otocorys alpestris) appear to be regular visitants, 

 and three [Ruticilla wolfi, Plectrophanes lapponica, and 

 Hirundo rustica) occasional stragglers. 



96. Krukenberg on the Colouring -matter of Feathers. 



[Die Farbstoffe der Federn. Von Dr. C. F. W, Krukenberg. Verglei- 

 chend-physiologische Studien, Heidelberg, Abth. v.] 



In this first communication on the colouring-matters o£ 

 feathers. Dr. Krukenberg describes the chemical reactions 

 and spectroscopic characters of three different substances 

 (Turacin, Zoonerythrin, and Zoofuloin) present in the red and 

 yellow feathers of birds. Turacin, as yet found only in the 

 feathers of the Musophagidse, particularly in the red feathers 

 of the wing, gives two different absorption-spectra, according 

 to whether it is in solution or not — a very unusual circum-
