United States who turned his attention to birds other than 

 those of North America. It is prefaced by a well-written 

 sketch of Cassin's life and work (prepared by Mr. Witmer 

 Stone) and gives a portrait of that excellent ornithologist, 

 whose personal acquaintance Sclater had the pleasure of 

 making when he visited Philadelphia in 1856 ! The papers 

 included are entirely of local interest.

[Synopsis Avium. Nouveau Manuel d'Ornithologie par Alphouse 

 Dnbois. Fasc. IX., X. Royal 8vo. Brussels, 1901-2. G francs per 

 livraison.] 



In these two parts of the ' Synopsis Avium ' (see Ibis, 

 1902, p. 338) the enumeration of the Oscinine series is con- 

 tinued to its end, and the few Pseudoscines conclude the 

 volume, which contains altogether 729 pages. The species 

 recognised in it are 9417 in number. The Introduction, 

 Titlepage, and Contents of the first volume of the ' Synopsis ' 

 are contained in the tenth livraison.

 Aves into '' Gymnopsedes " and " Ptilopsedes.'''' The first of 

 these sections is now concluded ; the Ptilopsedes will be 

 treated of in the second volume.

 Finsch. 56 pp. Berlin : Friedliinder, 1901.] 



By some mischance the 15th Lief erung of ' Das Tierreich/ 

 containing Dr. Finsch's synopsis of the Zosteropidse, which 

 is dated March 1901, has only lately come to our notice. It 

 was quite appropriate that this group of birds should be 

 worked up in the Ley den Museum, which contains an 

 excellent, if not unrivalled, series of Zosteropine forms. 



After an account of the literature of the subject, and two 

 pages of general introduction. Dr. Finsch proceeds to con- 

 sider the family, and wisely decides to allow only three valid 

 genera — Zosterops, Pseudozosterops, and Lophozosterops. To 

 tvpical Zosterops the author assigns no less than 138 species,
