AMERICAN BATS OF THE GENERA MYOTIS AND PIZONYX 27 



Saturatus {Myotis yumanensis) Miller, North Amer. Fauna, No. 13, 

 p. 68, October 16, 1897. This is the only name based on the dark 

 subspecies of yumanensis inhabiting the humid area of the northwest 

 coast of the United States and British Columbia. The type locality 

 is Hamilton, Skagit County, Wash. 



Septentrionalis (VespertiNo gryphus var.) Trouessart, Catal. Mamm. 

 viv. f OSS., p. 131, 1897. Trouessart established this name by latinizing 

 H. Allen's "northern form of VespertiUo gryphus'''' (Monogr. Bats 

 North Amer. (1893), p. 80, March 14, 1894). The animal to which it 

 was applied is the wide-ranging eastern long-eared bat for which 

 the name Myotis subulatus has been current during the past 30 

 years. Say's VespertiUo subulatus^ 1823, proves to have been not 

 this species but the one which has received the names leibii, cilio- 

 labruni^ melanorMnus, orinoTrms, and winnemana. As Trouessart's 

 name is the only one which was certainly based on the eastern 

 long-eared Myotis it must now be applied to that animal, but in the 

 trinomial form Myotis keenii septentiionalis. 



Simus {Myotis) Thomas, Ann. and Mag. Nat. Hist., ser. 7, vol. 7, 

 p. 541, June, 1901. This is the first and only name based on a very 

 distinct and peculiar South American species readily distinguishable 

 from all other known members of the genus. 



Sociabilis {Myotis yumanensis) H. W. Grinnell, Univ. California 

 Publ. ZooL, vol. 12, p. 318, December 4, 1914. This is the dull brown- 

 ish race of the large-footed M. yumanensis, inhabiting the semi- 

 arid region of the western United States, from Montana to the east- 

 ern part of the Pacific Coast States. The type locality is Fort Tejon, 

 Calif. 



Spixii {VespertiUo) Fischer, Synopsis Mamm., p. Ill, 1829. This 

 name was proposed as a substitute for VespertiUo brasiliensis of 

 Spix, 1823 (not of Desmarest, 1822). It is with little doubt a 

 synonym of Wied's V. nigy^cans published three years previously. 



Subulatus {VespertiUo) Say, Long's Exped. to the Rocky Moun- 

 tains, vol. 2, p. 65, footnote, 1823. The specific name subulatus has 

 been misapplied since 1864 to the common long-eared Myotis of east- 

 ern North America by practically all writers who have recognized 

 the animal as a distinct species. Recently accumulated evidence 

 shows, however, that it must now be restored to a different and still 

 imperfectly known bat ; that is, to the animal which, since its original 

 discovery by Say, has received in its several subspecific forms, the 

 names leibii (1842), ciUolabrum (1886), melanorhinus (1890), ori- 

 nomus (1903), and winnemana, (1913). The reason for this change 

 is twofold: First, the type locality of VespertiUo subulatus, on the 

 Arkansas River near the present town of La Junta, Otero County, 

 southeastern Colorado, is outside of the known range of the eastern 

 long-eared bat, and second, the original description, when read with
