 54 THE CONDOR I VoL. VIII Next, A. W. Anthony described from the waters adjacent to Lower California, O. kaedingi (Auk XV, Jan. x898, 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 5.7 2, tail 3.26, fork of tail o.4x, tarsus o.8L My series averages: wing 5.54, tail 2.84, fork of tail o.46, tarsus o.72. The size of kaedingi is thus very much less than in any of the other forms of the leucorlzoa 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- inga noticeable spot in 8300 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 plumbcons, not ashy. This petrel ranges from the vicinity of Gnadalupe Island north along the coast of southern California. It would seem from the nlaterial before hie, that there re- main two forms from the Pacific Coast worthy of recognition by nalne, as follows: Ocean0dr0ma beali new species. SPECIFIC C}l^R.CTls--Similar to O. leucorhoa, but of Ulfiformly smaller size. Tvrv;-- adult, No. 44o Coil. J. Grinnell; Sitka Bay, Alaska; August 5, 896. q2adult, No. 438 Coll. J. G. (same place and date). M^su.{ETS--, wing 5.9 o, tail 3.xo, forking of tail 0.80, tarsus 0,87. q2, wing 5.75, tail 3. m, forking of tail o.70, tarsus 0.90. COLo.^To--Sooty brown, darkest above; head, lower throat and back washed with plum- bcons; 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. R^Nc.E--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 U. S. Department of Agriculture. Ocean0dr0ma beldingi new species. SPECIFIC CH.^R^CT;Rs--Similar to O. beali, but decidedly grayer, and averaging notably smaller in length of wing and tail. TYP;--No. 53, Coil. Herman T. Bohlman; Netarts Bay, coast of Oregon; June 6, 9oL MEASUREMENTS--Average of 5 specimens: wing 5.65, tail 3.22, forking of tailo.67, tarsus 0.78. CoLoR.Tox--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. R.^NGE--North Pacific Coast, from Vancouver Island to northern California. Breeds on coast of Oregon (Win. Finley), and .Mendocino County, California (W. H. Dall). No'rE--I name this handsome new petrel in honor of our veteran California ornithologist, and Honorary member of the Cooper Ornithological Club,.
