Jones, J. Matthew. On some of the Rarer Birds of Nova 
Scotia. Proc. & Tr. Nov. Scot. Inst. Nat. Sc. ii. pp. 70-73. 
The species noticed are all aquatic ; and the rarest visitor is 
perhaps Tringa subarquata, which occurred in September 1868.

A good paper on the ornithology of the island, respecting which 
little has before been written. The author lived there two years, 
and includes 212 species in his list, nearly all of which he has 
himself identified. 
Ridgway, Robert. Notices of certain obscurely known species 
of American Birds. Proc. Acad. Nat. Sc. Philad. 1869, 
pp. 125-135. 
These are based on specimens in the Smithsonian Museum, 
and are made in especial connexion with the determination of 
collections formed by the author as zoologist to the Survey of 
the Fortieth Parallel, chiefly in California, Nevada, and Utah. 
After some preliminary remarks as to the line to be drawn be- 
tween species and varieties, in which the author states that 
he regards as conclusive the evidence with respect to the hybridi- 
zation of eastern and western representative forms, he proceeds 
to consider (1) the Thrushes of the genus Hylocichla, then (2) 
the uniformly red species of Pyranga (wherein a new species 
or variety is described) , and (3) the smaller Quiscali of the 
United States. 
Such particulars as are needful will be found under Turdida,

. This is the paper of which the abstract was noticed last year 
(Zool. Rec. V. p. 54). The author divides the country into three 
vertical zones — the Hot Zone reaching to about 600 metres, the 
Temperate between that and 1500, and then the Alpine. The 
resident species of Passeres (to which order his remarks are 
limited) seem to be 175 in number; and notes on all of them are 
given. Many more, however, are mentioned. The paper is an 
important and interesting one, as it treats of the district where the 
Nearctic and Neotropical Regions inosculate. For instance, the 
south-east of Orizaba is visited by many forms from the hot 
zone never found on the opposite side of the city, where represent- 
atives of the cold zone arc first met. A list of species for each of 
these zones is given, and some very good general remarks added. 
This paper should perhaps be regarded as relating to the “Neo- 
tropical Region.^^ \_Cf. Ibis, 1870, pp. 278-280.]
