States, Dr. Shufeldt gives us a considerable amount of 
informatiou on various points, and shews that the morphology 
of the group is particularly homogeneous. He selects 
Ectopistes as ^' a very good average Columbine type/^ and 
gives full details of its osteology, in comparison with those 
of Zenaidura, Zenaida, Engyptila, Melopelia^ Columbigallina, 
Scardafella, Geotrygon, and Starncenas, the last-named dif- 
fering somewhat from the others in its trunk- skeleton. 
Didunculus is treated separately and is figured, while for the 
genus Columba the author has been obliged to rely upon the 
work of his predecessors. The affinities of the group are 
shown to be with the Gallinaceous birds. 
72. Studer and Fatio on the Birds of Switzerland. 
[Katalog der Schweizerischen Vogel bearbeitet im Auftrag des eidgen. 
Departements des Innem (Abteilung Forstwessen) von Dr. Th. Studer 
und Dr. V. Fatio. Lief. III.* Pp. 193-418 ; 2 maps. 8vo. Bern, 1901.] 
Many observers have assisted the authors in the produc- 
tion of this carefully compiled Catalogue, of which the 
present part contains the Insessores, Coraces, Scansores, and 
a portion of the Captores, to use the names that evidently* 
reflect the preferences of the learned writers. Perhaps 
the most interesting species included are Merops apiaster, 
Coracias garrula, Pastor roseus, and Oriolus galbula, for 
which maps of distribution are given; with Picoides tri- 
dactylus and Bomby cilia garrula, for which none are thought 
necessary. The birds are considered from all points of view 
— as residents, migrants, and so forth; references to the 
literature are given in profusion for the several regions ; 
and other information is added ; the whole forming a standard 
work on Swiss Ornithology. 
73. Verrill on the '^ Cahow '^ of the Bermudas. 
[The Cahow of the Bermudas, an Extinct Bird. Ann. & Mag. Nat. 
Hist. (7) ix. p. 26.]
