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.

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, ||

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.
