not obtain, specimens of the Noddy of the Pacific coast, which 
Dr. Cones now separates under the name of A. frater .—O. S. 
16. Anous tenuirostris, Temm. 
The specimens are identical with examples labelled “A. tenui - 
rosins, Temm.,” in the museum of the Philadelphian Academy; 
and, so far as I can judge, this identification of them is correct. 
Setting aside the common A . stolidus and my A. firater , its Pacific 
representative, and some species, e. g. A. parvulus, Gould (A. 
dnereuSy Treboux), which have been improperly referred to the 
genus Anoiis, the remaining valid species are A . melanops, Gould, 
A. leucocapillus, Gould, and A. tenuirostris, Temminck, all three 
very closely allied to each other. I believe they may be briefly 
distinguished thus :— A . melanops has white under-eyelids, and 
the very dark circumocular region rendered still more conspi¬ 
cuous by the ashy hue of the lores. A . leucocapillus has no white 
on the under eyelid; and the lores are of one colour with the 
dark circumocular region. A . tenuirostris , like A. leucocapillus , 
has the lores very dark coloured ; but it has white under-eyelids. 
It is also notably smaller.

The collection thus embraces fifteen or sixteen species of 
eight genera of two subfamilies of Laridce.

The c Edinburgh New Philosophical Journal’ for October 1863 
contains “ Some Observations on the Eggs of Birds,” from the 
pen of Dr. John Davy. These chiefly relate to the nature and 
properties of the colouring-matter, and to the results of certain 
experiments on the albumen. With regard to the former sub¬ 
ject, Dr. Davy appears, generally, to have come to the same 
conclusion as Professor Wilke (‘ Naumannia/ 1858, p. 393) and 
M. Leconte (Ilev. et Mag. de Zoologie, 1860, p. 199) have done, 
namely, that the colouring-matter te is not in any way owing 
to the presence of iron,” and consequently is not derived from 
the blood—an opinion contrary to that maintained, we believe, 
by M. 0. DesMurs in his celebrated f Oologie Ornithologique.’
