_Measurements._—Wing, 54; tail, 68; bill, 13 mm.
=Pseudocolaptes boissoneautii oberholseri= subsp. nov.
_Type_ from Quito, Ecuador. Adult male, No. 30945, United States National Museum, Washington, D. C. Collected by C. R. Buckalew.
_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.

=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._
