subject is explained and discussed, we have a long chrono- 

 logical list of the literature of Arctic Birds, which begins 

 with Martens in 1675 and ends with Proctor and Saunders 

 in 1904. Omissions may be discovered in this, but it seems 

 to be nearly complete and is followed by a very useful index, 

 by which the special authorities on the different localities 

 may be found without delay. This is followed by a nominal 

 list of the species of the " North-Polar Ice-Sea " and its 

 islands, and then by a discussion of the exact range and time 

 of occurrence of the 270 species and subspecies attributed 

 to it. Every species, whether it belongs to the Palsearctic 

 or Nearctic Avifauna, is fully considered, and the authorities 

 for its occurrence in Arctis are fully stated. We may regret 

 that the author should call the Grebes " Colymbus" and 

 misspell " Otocorys " ; but such is the fashion of the day, 

 and we submit to it with a slight murmur. 



After the remarks on the species and subspecies, a list is 

 given of those met with in each separate locality — Bear 

 Island, Spitsbergen, Franz-Joseph Land, Nova Zembla, 

 Kolguef, Dologol, Waigatsch, the New-Siberian Islands, 

 &c, finishing with those of Greenland and Jan Mayen. 

 This is likewise a very useful feature in the memoir, which 

 we can commend to the attention of all those interested in 

 Palsearctic Birds. 



The final chapter of comparison between the Arctic Ornis 

 and the Antarctic Ornis only serves to shew that they are 

 quite different. It was until lately supposed that Sterna 

 macrura was to be met with in both of them, but (alas !) the 

 southern bird has recently been converted into a new "sub- 

 species " Sterna macrura antistropha !
