THE CONDOR 
| Vox,. VIII 
Next, A. W. Anthony described from the waters adjacent to Lower California, 
O. kacdingi (Auk XV, Jan. 1898, p. 37). In reviewing the material before me (27 
skins) referable to this species, I find the average measurements to be less than 
those given by Anthony. His type measured (millimeters reduced to inches): 
wing 5.72, tail 3.26, fork of tail 0.41, tarsus 0.81. My series averages: wing 5.54, 
tail 2.84, fork of tail 0.46, tarsus 0.72. The size of kaedingi is thus very much less 
than in any of the other forms of the leucorhoa group. In color, kaedingi is much 
the darker, being dark sooty brown over the whole body, while the head is dark 
plumbeous. The rectrices are sooty thruout, or else but very slightly paler at the 
base. However, the tip of the inner web of outer tail-feather is often paler, form- 
ing a noticeable spot in 83°,, of my specimens. I have found this character in no 
other case, excepting one Atlantic skin (No. 94,554 U. S. N. M.), and in that one 
only on one outer rectrix. The tail in kaedingi is less deeply forked than in the 
more northern Pacific Coast forms, and the head is dark plumbeous, not ashy. 
This petrel ranges from the vicinity of Guadalupe Gland north along the coast of 
southern California. It would seem from the material before me, that there re- 
main two forms from the Pacific Coast worthy of recognition by name, as follows: 
Oceanodroma beali new species. 
Specific Characters— S imilar to O. leucorhoa , but of uniformly smaller size. 
Type — (5 adult, No. 1440 Coll. J. Grinnell; Sitka Bay, Alaska; August 5, 1896. $adult, No. 
1438 Coll. J. G. (same place and date). 
Measurements — $ , wing 5.90, tail 3.10, forking of tail 0.80, tarsus 0,87. 5, wing 5.75, 
tail 3.10, forking of tail 0.70, tarsus 0.90. 
Coi.or aTion — Sooty brown, darkest above; head, lower throat and back washed with plum- 
beous; forehead and chin smoke gray; greater and median wing-coverts light smoke gray; upper 
tail-coverts white with black shafts; lateral lower tail-coverts edged with white; rectrices black 
with white at base. 
Range— North Pacific Ocean, south to Prince of Wales Island. Breeds on Aleutian and 
Copper Islands and on islets in Sitka Bay, Alaska. 
Note — I take pleasure in naming this far northern petrel in honor of one who is doing so 
much of value in working out the economic standing of our Pacific Coast birds: Prof. F. E. L. 
Beal, of the l'. S. Department of Agriculture. 
Oceanodroma beldingi new species. 
Specific Characters — Similar to O. beali, but decidedly grayer, and averaging notably 
smaller in length of wing and tail. 
Type — N o. 53, Coll. Herman T. Bohlman; Netarts Bay, coast of Oregon; June 6, 1901. 
Measurements — Average of 5 specimens: wing 5.65, tail 3.22, forking of tailo.67, tarsus 0.7S. 
Coloration — Uniform sooty brown, washed with a bluish slate-gray on head, throat, chest 
and back, the gray most pronounced on head and chest; forehead, chin and upper throat de- 
cidedly ashy; greater and median wing-coverts edged with ashy; upper tail coverts white with 
black shafts; lateral lower coverts edged with whitish; rectrices black with white at base. 
Range — North Pacific Coast, from Vancouver Island to northern California. Breeds on 
coast of Oregon (Wm. Finley), and Mendocino County, California (W. H. Dali). 
Note — I name this handsome new petrel in honor of our veteran California ornithologist, 
and Honorary member of the Cooper Ornithological Club, Mr. Lyman Belding.

Two petrels from off the coast of San Mateo County, south of San Francisco, 
are referable to O. kaedingi and may possibly be the same form as was found
