One hundred and sixty-three species are enumerated, and a few notes from 
the author’s personal ohservation are added.

Azores. Ibis, 1866, pp. 88-109, pi. hi. 
The author stayed about three months in the arehipelago on 
purpose to collect their birds and insects. After describing his 
movements among the islands, he enumerates the different spe- 
cies, 52 in number, which occur there. Of these, two, both be- 
longing to Fringillid(By are peculiar to the Azores, and one of 
them is now correctly described for the first time; but of several 
others local forms exist almost entitled to specific recognition. 
The ornithology of the archipelago, and the distribution of the 
species in it, seem to furnish strong evidence against the theory 
that they are the descendants of those which inhabited a conti- 
nent now submerged. The author believes that all the species 
found in it have been introduced (some of them, may be, at a re- 
mote period) by storms, and that this process of. introduction is 
being continued at present. There is a decided tendency among 
Azorean forms to acquire a darker plumage, together with 
stronger bills and legs than are possessed by their continental 
representatives. The islands which lie most to the eastward 
have the most species, and the number diminishes gradually to- 
wards the west. A compendious table, showing the geographical 
distribution of Azorean birds, is included in the paper, which is 
elaborated with much care, and is of an eminently suggestive 
character.

. Two hundred and twenty-five species are stated to have been 
observed in the county ; and remarks on their habits, times, and 
localities of occurrences are given, as well as the musical expres- 
sion of their call-notes. Without containing any very novel in- 
formation, this little work possesses considerable interest, and is 
most conscientiously executed. {Cf. Ibis, 1867, pp. 123-125.)
