Description. — Ears moderate, leathery, semi-erect, turned 

 slightly outwards, convex on the inner border, nearly straight 

 on the outer, in some slightly emarginate ; the lower third of this 

 portion is slightly revolute outwards ; basal lobe well developed. 

 Tragus nearly half as high as auricle, straight on inner border, 

 moderately convex and diverging on outer ; sometimes the tip is 

 more acute than in other species, but is never pointed ; in some 

 specimens it has a very slight incurvation. 



The coloring is very similar to S. carolinensis, being dark 

 plumbeous at base, with chestnut-brown tips above, and light

 exhibits some slight differences in different specimens : thus the 

 back may be more of a light russet, and that in front more of a 

 whitish hue. The extent of the plumbeous is also subject to 

 variation, in some specimens occupying but the lower third of the 

 hair ; while in others — and this is more apt to occur on the front —
