129. Salter on Cardiganshire Birds. 
[List of the Birds of Aberystwyth and Neighbourhood. By J. H. 
Salter. 8vo. Pp. 19. Aberystwyth, 1900.] 
Local lists of Welsh birds by competent field-naturalists 
are few and far between, so that Mr. Salter's contribution is 
very welcome, for the district of Cardiganshire in question 
has been little noticed by the ornithologist. The Notes on 
the 206 species recorded are brief, but they are to the purpose 
and all that can be desired. 
130. Sharpe on the Birds of Christmas Island. 
[A Monograph of Christmas Island (Indian Ocean). Physical Features 
and Geology by Charles W. Andrews. With Descriptions of the Fauna 
and Flora by numerous Contributors. (Birds by R. Bowdler Sharpe, 
LL.D., &c.). 8vo. London, 1900.] 
Mr. Andrews's researches have doubled the number of the 
known birds of Christmas Island, as Mr. Lister’s list (P. Z. S. 
1888, p. 512) only gave the names of 14 species, and 29 are 
now recorded. But the additions are all of species of 
occasional or erratic occurrence and mostly of wide distri¬ 
bution, and the resident land-birds of this curious islet remain 
7 in number, all peculiar. It is a pity that the distribution 
of the occasional visitors is not more fully stated in the 
monograph, in order to give us some better idea of the 
origin of the bird-life of Christmas Island. 
131. Stone on Birds from Alaska. 
[Report on the Birds and Mammals obtained by the Mcllhenny Expe¬ 
dition to Pt. Barrow, Alaska. By Witmer Stone. Proc. Acad. Nat 
Sci. Philad. 1900, p. 4.] 
Mr. Stone writes on the “ splendid collection of birds and 
mammals" obtained by Mr. E. A. Mcllhenny during his 
sojourn at Point Barrow, Alaska, in 1897-98. The series of 
birds comprises 1408 specimens, representing 69 species, of 
which 60 are from Point Barrow. Of these 13 are additional 
to the previous list of Murdoch *, and one (Eudromias mori- 
nellus) is new to the North-American avifauna. Various
