Characters.—Similar to P. b. boissoneautii (Lafresnaye) from Bogota, but differs in having the throat and ear tufts quite white and the “scale” marking on the breast larger and more pronounced; belly and flanks more olive rusty; tail darker and more brownish chestnut rufous.
Measurements.—Wing, 107; tail, 99; bill, 20 mm.
Remarks.—An immature specimen from Nanegal, Ecuador, in the collection of the Museum of Comparative Zoölogy has the whole top of the head blackish and the belly and flanks bright rusty rufous. A specimen labelled Guayaquil (locality probably not correct) in the U. S. National Museum, agrees fairly well with the type, but has the sides of the belly and flanks more olive rufous. I have dedicated this new form to Dr. Harry C. Oberholser.
GENERAL NOTES.
Procellariidæ versus Hydrobatidæ.—The discovery that the generic name Procellaria Linnæus belongs to the group commonly called Majaqueus Reichenbach (cf. Mathews, Novit. Zool., XVII, December, 1910, p. 497) makes necessary a change in the family name Procellariidæ. On account of the adoption of Thalassidroma Vigors for Procellaria auct. nec Linnæus, the family name Thalassidromidæ has been used (Committee of Brit. Ornith. Union, List Brit. Birds, ed. 2, 1915, p. 281). Since, however, the generic name Thalassidroma has been properly retired in favor of Hydrobates Boie, the family name Thalassidromidæ must accordingly be altered to Hydrobatidæ, as has already been done by Mr. Mathews in his ‘Birds of Australia,’ (Vol. 2, No. 1, May 30, 1912, p. 9).—Harry C. Oberholser, Washington, D. C.
Long-tailed Jaeger in Indiana.—A beautiful specimen of the Long-tailed Jaeger (Stercorarius longicaudus), taken at Millers, Ind., November 30, 1918, was seen by me in a Chicago taxidermist’s shop. Knowing of only three previous records of the bird’s appearance in the Chicago area, I purchased the bird and it is now in my collection. The first record was made by Mr. Stoddard of the Field Museum and the other two by Mr. Woodruff of the Chicago Academy of Sciences (Auk, Vol. 35, p. 234). Mr. Cory of the Field Museum kindly verified its identity and as this forms the fourth instance of the bird’s occurrence within our boundaries it should be of interest. It is in the immature plumage with the tail-feathers only partially developed.—Nathan F. Leopold Jr., Chicago, Ill.
Larus canus brachyrhynchus in Wyoming.—A Wyoming specimen of Larus canus brachyrhynchus, a male in juvenal plumage, has for many years been in the collection of the Biological Survey, in the United States National Museum. It is No. 141395, U. S. Nat. Mus., and was taken on Lake Fork, a tributary of the Green River, at an altitude of 10,000 feet in the Wind River Mountains, Wyoming, on August 28, 1893, by Mr. Vernon Bailey. It has already been recorded incidentally (Cooke, Bull. U. S. Dept. Agric, No. 292, October 25, 1915, p. 47), but owing to its importance it seems worthy of special notice in a place more accessible to ornithologists generally. It represents the easternmost record of Larus canus brachyrhynchus, and the only really interior occurrence of the species in the United States. For the change of the name of this bird from Larus brachyrhynchus to Larus canus brachyrhynchus see ‘The Auk,’ XXXVI, No. 1, January, 1919, p. 83.—Harry C. Oberholser, Washington, D. C.
Polysticta Eyton versus Stelleria Bonaparte.—Mr. G. M. Mathews has recently (Austral Avian Record, III, No. 5, December 28, 1917, p. 123) advocated the use of the generic name Stellaria Bonaparte for the species now known as Polysticta stelleri (Pallas). The term Stelleria is, of course, as he shows, not debarred from employment in zoölogy by the previous use of Stellaria in botany; but he has apparently overlooked the fact that Polysticta is not preoccupied, since Polysticte Smith (Illust. South Afr. Zoöl.), June [or later], 1836, does not invalidate Polysticta Eyton (Catal. Brit. Birds), April, 1836, a fact to which Dr. C. W. Richmond long ago (Proc. Biol. Soc. Wash. XVI, September 30, 1903, p. 128) called attention. It is evident, therefore, that the name of Steller’s Eider should remain Polysticta stelleri (Pallas).—Harry C. Oberholser, Washington, D. C.
