42. Finsch’s Review of his Forty Years 9 Work. 
O. Finsch : Systematisclie Uebersicht der Ergebnisse seiner Reisen 
und schriftstellerischen Thatigkeit (1859-1899). 8vo. Berlin, 1899.] 
The excellent work in zoology and anthropology accom¬ 
plished by our old correspondent, Dr. Finsch, during the 
past 40 years, well deserves this permanent record, which is, 
at the same time, very useful to students for purposes of 
reference. In “ Birds,” as we all know, Dr. Finsch has 
been specially active, and his papers, which form a goodly 
list, show his researches in Greenland, Europe, Africa, 
Asia, Indo-Malaysia, New Guinea, the Pacific Islands, and 
New Zealand. According to the alphabetical list given, the 
new species described by Dr. Finsch are 158 in number. 
We cordially wish him a long period of . fresh activity in the 
Leyden Museum.

Notes- The portion relating to “Birds” occupies 11 pages of 
the Appendix, and contains an account of two collections : 
the one made in the valleys round the base of the great 
mountain, and the other during Mr. Gosse's two months' 
residence at Lujan, in the province of Mendoza. In the 
first list 26 species are mentioned, and field-notes are given 
relating to each of them; all being well-known Chilian 
species, and such as would be expected to occur in the 
Mendozan Andes. Atticora cyanoleuca was observed up to 
11,000 feet; Oreotrochilus leucopleurus was found breeding 
in the Inca Valley in December and January, and another 
Humming-bird (probably Patagona gigas) was noticed but
