rations made in the Baltic provinces of Russia during tlie 

 season o£ 1886 consists of two portions. The first of these 

 gives a list and short description of the ten stations^ the 

 second a systematic account of the observations on each 

 species. The latter list contains notes on only 109 species; 

 of these almost the only Passerine not well known to us is 

 Carpodacus erythrinus, which is common in some parts of 

 the Baltic Provinces.

The original basis of this excellent resumd of the ornitho- 

 logy of the Comoro Islands is the collection made by 

 M. Humblot in the Comoros in 1884 and the two following 

 years, which was described in the 'Annales des Sciences 

 Naturelles' in 1887"^. The authors now add to their pre- 

 vious information, and work into their memoir the results 

 obtained by former authorities on the same subject, so as to 

 give a complete account of the ornis of the Comoros and of 

 its relation to other countries. M. Humblot's researches 

 make us acquainted with 65 species belonging to this 

 avifauna, and 14 others had been recorded by previous 

 authorities, but were not met with by M. Humblot. Thus 

 the whole avifauna, according to the present state of our 

 knowledge, embraces 79 species, of which a carefully drawn 

 geographical table is given to show their distribution in the 

 Comoro archipelago and in other countries. About J20 of 

 these species are peculiar to the Comoros, but are mostly 

 slightly altered forms of species known elsewhere, and not, 

 in many cases, referable to genera exclusively Madagascarian. 

 Moreover none of the most characteristic Madagascarian 

 types (such as Atelornis, Brachypteracias, Euryceros, and 

 Coua) are found in the Comoros, and the conclusion arrived
