This paper contains an account of the collections made by 
Dr. Finsch and his companions during his well-known S$1- 
berian expedition of 1876. Of birds, examples of 283 species 
were obtained, concerning which we have many excellent 
field-notes. Certainly the occurrence of Tetraogallus hima- 
layensis (p. 125) in this part of Siberia is difficult to be ex- 
plained; but we believe there is no doubt that the species has 
been correctly determined. 
73. Gould on two new Humming-birds from Bolivia. 
[Description of two new Humming-birds from Bolivia. By John Gould, 
F.R.S. Ann. & Mag. N. H. ser. 5, v. p. 488.] 
Both these birds are figured in the first part of Mr. Gould’s 
supplement to the Trochilide, noticed below. Cynanthus boli- 
vianus, the first species, is a close ally of C. mocoa, and, ac- 
cording to Mr. Elliot (Ann. & Mag. N. H. ser. 5, vi. p. 282), 
not to be distinguished from that bird. Pinarolema buckleyi 
belongs to a new genus allied to Lampornis and Oreotrochilus, 
but has a long wing, strongly curved lengthened bill, broad 
tail-feathers, and extremely small feet. Both species were 
obtained by Mr. C. Buckley in Bolivia. 
74, Gould’s ‘ Supplement to the Trochilide’ 
[Supplement to the Trochilidee or Humming-birds. By John Gould, 
F.R.S. Part I. Folio. August 1, 1880.] 
It is the usual fate of any one who writes a monograph to 
see on the completion of his work a host of novelties brought 
before him, but too late to be included in his book. This has 
been eminently the case with the Trochilide. Since Mr. 
Gould finished his magnificent five-volume folio, some twenty 
years ago, new Humming-birds, remarkable both for their 
peculiarity and beauty, have been arriving from America till 
the number of these additional species now reaches fifty or 
sixty. Anxious to bring his work to the standard of the
