General Notes. 227 Agelaius phoeniceus floridanus Maynard (1896) therefore becomes a synonym of Agelaius phoeniceus phoeniceus (Linnaeus, L766), and the northern subspecies must be known as Agelaius phoeniceus predatorius ( Wilson ). NORTHEASTERN RED-WING. Sturnus predatorius Wilson, American Ornithology, IV, 1811, p. 30, pi. 30, figs. 1 and 2. Characters. — Larger than Agelaius phoeniceus phoeniceus* with a shorter and stouter bill. Female darker, especially below, where the black stripes are much broader, t Geographical distribution. — This form breeds from Fort Macon, North Carolina, and Smith's Island, Virginia, north to Nova Scotia, and west-ward, wintering as far south as ( ieorgia and the Gulf States. % Remarks. — Wilson's figures, descriptions and measurements all rep-resent the northern subspecies; and his reference, in synonymy, to specimens in Peale's Museum ( " No. L466, 14G7") make it probable that his material came from eastern Pennsylvania, which region 1 therefore fix as the type locality of his Sturnus predatorius. — Edgar A. Mearns. NOTE OX THE MEXICAN BATS OF THE GENUS DASYPTEEUS^ Mr. Geo. F. Gaumer has recently presented to the U. S. National Museum some specimens of Dasypierus taken at Izamal and Yaxcash, Yucatan, which represent two very distinct species. One is a large animal witli skull about 18 mm. in condylobasal length, while the other is noticeably smaller; condylobasal length of skull about 15 mm. The difference in size between the two animals is thus about the same as that separating the European Nyclcdus noctula and N. leisleri. Apparently tins is the first instance on record of the occurrence of two members of the Deisypterus ega group at one locality. The smaller animal, represented by adults only, appears to be the D. ega panamensis of Thomas; unquestionably it is a local representative of true ega, a species which in its various geographic forms ranges from Argentina to Lower California. It maintains a uniformly small size throughout a very extended area, the range of individual variation in condylobasal length of skull in specimens from Paraguay, Brazil, Bolivia, Yucatan and Lower California being from 14 to 15.6 mm. The larger species, represented by both adults and young from Yucatan, is equally constant, as the range of variatii >n in adult skulls from Yucatan, Chiapas, || *See Ridgway's Birds of North and Middle America, vol. II, 1902, pp. :;:;i and 333. iThe darkest female specimens in the collection of the United states National Museum were collected at Plum Island Marsh. Kssex County. Massachusetts, by Mr. William D. Carpenter, in June, 1911. X Numerous winter specimens of both sexes, from South Carolina, in the U. 8. National Museum collection, are all predatorius. 5 By permission of the Secretary of the Smithsonian Institution. [Adult male (skin and skull).
