Count Salvadori to 10 species, besides a certain number of 

 eggs. But the birds are by no means without interest, as 8 

 of them are from Prince Rudolph Island, the most northern 

 of the Franz-Joseph group, where the expedition passed the 

 winter. The only Passerine bird in the list is Plectro/dienax 

 nivalis, of which examples were obtained in May and June 

 1900. 



The introduction contains an excellent summary of previous 

 authorities on the birds of Franz- Joseph Land. The egg 

 of Pagophila eburnea is figured. 



For a complete account of the Duke of AbruzzPs adven- 

 turous journey, we may refer our readers to " On the ' Polar 

 Star'" (two vols., Hutchinson & Co., 1903), a most inter- 

 esting and beautifully illustrated work, with many references 

 to birds.

The distinguished Italian explorer Sig. Leonardo Fea has

 and Count Salvadori has undertaken the task of working

 account of previous authorities on the birds of the island of 

 Principe and a complete bibliography, the Count states that 

 the 41 specimens obtained by Sig. Fea are referable to 16 

 species, of which one, Tardus ocanthorhynchus (already cha- 

 racterized in Boll. Mus. Torino, no. 114, p. 2), is new to 

 science, and another, Phoeniconaias minor, is new to the island- 

 fauna. A complete list, with synonymy and remarks is 

 then given of the 43 species as yet ascertained to occur in 

 the island. 



It is a remarkable fact that neither diurnal nor nocturnal 

 birds-of-prey have yet been found in the island. The general 

 facies of the avifauna is decidedly West-African, but there
