202 Recently published Ornithological Works. 
the species of birds collected or observed in these two localities; 
(2) a synopsis of Kamtschatkan birds; and (3) the author's 
conclusions 33 —-three essays which are certainly worthy 
of careful attention. The species collected or observed in the 
Commander Islands and Kamtschatka by Mr. Stejneger were 
140 in number, of which 35 were Passeres. Full details are 
given of the synonymy and nomenclature of each of them, 
besides an account of their habits and method of occurrence 
in the districts spoken of. We fear, however, that some con¬ 
sternation will be caused on this side of the Atlantic by the 
names employed in certain cases. These names are stated 
to have been arrived at on the principles laid down by the 
American Ornithologists' Union, and, as the author candidly 
admits, will be found to deviate “ not inconsiderably " from 
those usually adopted*. Very full and interesting accounts 
are given of the Auks and Puffins of the Northern Pacific 
and their curious seasonal changes, which are illustrated by 
several coloured plates. “ Charitonetta 33 is proposed as a 
new generic name for Anas albeola , Linn. 
In the Synopsis of Kamtschatkan Birds, which forms part 
ii. of the volume, 186 species are included, and two more are 
added in an Appendix, on Dybowski's authority. 
In the conclusions 33 the general facies of the avifauna of 
this part of the world is discussed; and it is shown that the 
Ornis of the Commander Islands is chiefly Kamtschatkan, 
“ since only 11 species have been taken in them which do 
not belong to the Kamtschatkan fauna."

Our congratulations are due to M. Taczanowski on the 
* As the author is a stickler for correct names, it may he remarked 
that 11 Eniconetta ” (p. 170) should be written “ Heniconettaf the deriva¬ 
tion being cvikos, singular, and that “ Somateria v-nigra ” (op. cit. p. 173) 
was properly altered by Bonaparte to S. v-nigrum y as the adjective 
should agree with the neuter “v,” not with the feminine “Soma¬ 
teria.” Again, the generic term “ Ay thy a” if used, should be trans¬ 
literated “ zEthyia,” from the Greek aWvia.
