the region. These were prepared by Mr. Wal- 
ter Deane, Mr. Brewster’s Assistant, and give 
evidence of much pains-taking labor, which 
only those who have attempted similar work 
can appreciate. 
While evidently exhaustive for the Cape 
Region of Lower California, and meant to cov- 
er that region chiefly, the accounts of many 
species cover the whole peninsula and often 
extend to include the entire coast. Thus im- 
portant remarks are made in regard to a num- 
ber of birds in Southern California and the 
.State generally. Dendroica cssiiva souorana 
is for the first time attributed to California on 
the basis of a skin in Mr. Brewster’s collection 
taken by .Stephens at Riverside, Sept. 14, 1881. 
This race of the yellow warbler may therefore 
be expected as a spring visitant to the extreme 
southwest corner of the State. 
We of the Pacific Coast are grateful to Mr. 
Brewster for the present comprehensive review 
of the birds of the Cape Region. It is very 
convenient to have at hand a paper of the pre- 
sent character to which one may turn for the 
latest information on the region, knowing it to 
be authoritative as well. One not familiar 
wdth the scattered local literature might floun- 
der about for hours for some fact in the distri- 
bution or life history of a southern species, 
when a moment’s reference to such a paper as 
this would settle the point so far as known. 
We can only wish for more works of a similar 
nature for the different areas of the West. —

Ch,m>man’ on Al.v.skan Bird.s*— Mr. Chap- 
man reports on a collection of birds received 
from the Kenai Peninsula and vicinity, giving 
a. list of sixty-eight species with notes by the 
field collector. The w'estward extension of the 
known ranges of Dendroica toiV 7 ise?idi, Spiiius 
piniis and Empidonax trailli is of particular 
note. Mr. Chapman adds critical notes of gen- 
eral interest on several species. The nomen- 
clature of the Pants hiidsonicus group of forms 
receives another shuffle, the third -within a few 
years. Lagopits leucurus pcninsularis is de- 
scribes as new, and at the same time the Rocky 
Mountain race {altipetens) is lumped with 
Lagapus leucurus proper. This is simply re- 
versing the case as worked out by Osgood two 
years ago. Also a form of the Steller jay 
which he names Cyanocitta ste/leri borealis is 
described from the Kenai Peninsula. It is “in- 
termediate in "color between the Queen Char- 
lotte Island bird and that inhabitating the (ad- 
jacent) coast,’’ though geographically removed 
from the former. Judging from the description

the distinguishing characters are as slight as 
have been so far adduced by any author to con- 
stitute a nameable form. We believe that all 
discernible geographical races occupying defin- 
ite areas should be supplied with a name, even 
though they be recklessly diagnosed as “not 
worth the naming” by many specimen-labellers 
and popular writers. Evidently from the pres- 
ent paper and other scientific articles by the 
same author Mr. Chapman believes so too. 
But the Audubonist who reads only “Bird- 
Lore” would not think so after perusing the 
various editorials and reviews in that magazine.

Snodgras.s and Heeeer on Birds of 
C l.IPPERTON AND Cocos ISEANDS."®^ — The 
present paper opens with a description of 
the physiographic features of Clipperton And 
Cocos Islands, the former having “the distinc- 
tion of being the only coral island in the east- 
ern Pacific. 
Under the Systematic Account of Birds are 
listed fifteen species, five of which are land 
forms: Coccyzus fernigineus,Nesotriccus ridg- 
wayi, Cocornis agassizi, Dendroica aureola 
from Cocos, and Che li don erythrogate'r? from 
Clipperton. The greater part of the paper con- 
sists of technical descriptions of the species. 
The measurements given of Gygis Candida 
{ = G. alba Sparrni.) would indicate the form 
called Gygis alba kittlitzi, by Hartert (Caroline 
Is.). Micratious diamesus, discovered by the 
expedition, is intermediate between M. leuco- 
capillus and M. liawaiiensis. A comparison of 
the type of diamesus with several fully adult 
specimens of hazvaiiensis from Laysan Id. 
shows that the color differences can not be de-- 
pended upon inasmuch as the color of hawaii- 
ensis is variable, a specimen matching quite 
satisfactorily the type of diamesus. Further- 
more the bill of the fully adult hawaiiensis 
specimens are the same length as that of the 
type of dianiesus. The species must rest then 
on the slightly longer wing, tail, and middle 
toe, and stouter bill. Sula nesiotes from Clip- 
perton is a species similar to Sula brewsteri, 
somewhat larger with the brownish color of the 
head and upper parts considerably paler. The 
measurements of Cocornis agassizi are unfortu- 
nately listed as of “C. ridgwayi." 
The expedition so successfully carried on in 
1898-99 by Mr. vSnodgrass and Mr. Heller added 
to the region under consideration Micranous 
diamesus and Sula nesiotes. both new. The pres- 
ent paper is certainly an important addition to 
our knowledge of the ornis of Cocos and Clip- 
perton Islands. — W. K. F.
