Type locality. — Georgia; probably the LeConte plantation, near 

 Riceboro, Liberty County. 



Type specimen. — None designated. The British Museum has a 

 made-over skin received with the Tomes collection, that was origi- 

 nally No. 4741 of the United States National Museum. It is labeled : 

 VespertUio " lucifugus^'' United States, Maj. LeConte. This is a 

 typical Myotis lucifugus lucifugus as now understood, and may well 

 be one of the specimens on which LeConte based his original account 

 of the animal. 



Distribution. — The entire forested portion of North America north 

 of the southern border of the United States except in the Rocky 

 Mountain region and on the Pacific .coast of California, Oregon, 

 Washington, British Columbia, and southern Alaska. (See map 1, 

 p. 38.) 



Diagnosis. — Color above ranging from yellowish brown (bronzy) 

 to olive brown; a dark area at the shoulder; belly gray with a rich 

 buffy suffusion; membranes not pale-edged; ratio of foot to tibia 

 usually ranging from about 53 to 54. 



Description. — Two extremes or phases of color are found in the 

 east. In the one the fur above is a glossy yellowish brown almost 

 bronze, in the other it is browner (U. S. N. M., No. 159411 from 

 Young Harris, Georgia) nearly " ochraceous-tawny " (of Ridgway, 

 1912) varying individually in the depth of the bronzy tint to an olive 

 brown (near "Dresden brown"). At the shoulder there is a small 

 contrasting area of darker, nearly blackish brown, forming an ill- 

 defined spot. Bases of the hairs above and below blackish or dark 

 plumbeous. The hairs of the lower surface are tipped with a rich 

 buff, nearly the chamois of Ridgway, those at the extreme posterior 

 part of the body without dark bases. Immature individuals are 

 sooty gray above, the glossy tips of the hairs inconspicuous. Ears 

 and membranes blackish brown. 



Measui'evients. — For measurements see tables, pages 56 and 59.
