with. Amongst these was Turtur saturatus, restricted to 

 this locality. Twelve species were found on Assumption 

 Island, amongst which was a new Rail {Dryulimnas abbotti), 

 a new Booby {Sula abbotti), and a new Sun-hird {Nectarinia 

 abbotti). On Gloriosa Island examples of 22 species were 

 obtained or observed, of which 4 were Passeres, and Ixocincla 

 madagascariensis rostrata is a doubtfully new subspecies. Of 

 Aldabran birds no fewer than 45 are enumerated, of which 10 

 are Passeres. The European Sand-Martin {Cotyle riparia) 

 was found on Gloriosa and Aldabra. A very useful table of 

 distribution of the 212 species recognized as occurring in the 

 various islands is given at the end of the article. It is a pity 

 that a map, showing the exact positions of the island-groups 

 and their distances from each other, is not appended.

Rhamphocoelus fest(e is a new species allied to R.passerinii, 

 but distinguishable by its smaller size and red breast-band. 

 The type-specimen was obtained by Dr. Festa during a recent 

 traverse of the isthmus of Darien, and was presented by him, 

 along with other specimens, to the Zoological Museum of 

 Turin.

[Im Australischen Buscli und an der Kiisten des Korallenmeeres. 

 Keiserlebnisse und Beobachtungen eines Naturforschers in Australien, 

 Neu-Guinea und den Molukken, von Richard Semon, Professor in Jena.

This is one of the best books of travel and natural history 

 that we have read for a long time, and may be compared 

 favourably even with those of such past-masters in this 

 department as Wallace and Bates. Prof. Semon went out 

 to Australia to study the development of Monotremes, ]\Iar- 

 supials, and Ceratodus, in AThich he appears to have attained 

 undoubted success. On his journey home he visited the
