of works re-arranged under each of them. As, however, the 

 general list has been shewn to be very imperfect, this must 

 necessarily be also the case with the various special lists. 

 Besides this, the special headings are far too numerous, 

 and in some cases obviously misleading. " Postembryonic 

 Ontogeny " (!) is credited with two papers which might just 

 as well have been ranged under " Development." We had 

 supposed that the possibility of " Hibernation " in Birds 

 was no longer credited, but four papers are placed under 

 this curious heading. To "Pelagic Animals" one paper is 

 assigned : it seems to consist merely of remarks on bird-life 

 on the coasts of the Arctic Seas. Why Mr. Campbell's 

 work on 'Australian Birds' Nests and Eggs ' should have 

 been selected to be placed under "Variation and ./Etiology " 

 we cannot understand. " Geographical Distribution " is, of 

 course, a very important subject, but the mode of arrange- 

 ment adopted here is very confusing. It is surely unnecessary 

 to break up " North America " into seven different sections, 

 and " Australia" into four. Altogether there are more than 

 sixty different headings in this section. They should have 

 been reduced to one-third of that number. 



Finally, the alphabetical "List of new Genera and Species" 

 would be very useful if it were correct and complete ; but 

 even the new species characterised in the 'Bulletin of the 

 British Ornithologists' Club' in 1901 are in many cases passed 

 over*. When the new genus or species is given, the only 

 reference added is that of the number of the paper in the 

 " Authors' Catalogue," and the enquirer has to refer back to 

 the Authors' Catalogue for the title of the work and then to 

 hunt up the page for himself. 



It is obvious from what we have stated, and from what, as 

 we are told, is the somewhat similar case in other parts of 

 the zoological volume of this work, that the ' International 

 Catalogue ' so far as regards zoology is not a success.
