AMERICAN BATS — ^HANDLEY 119 



Table 4. — Morphological characteristics of bats of the genus Lasiurus 



Barbastella is unique in the degree of posterior extension of the 

 anterior nares, which reach so far back that the vomer is exposed 

 as a median spine. Its muzzle glands are almost as large as those in 

 the subgenus Corynorhinus. A pair of deep grooves extend from the 

 nostrils to the upper lip. The auricles are peculiarly short and broad 

 and are connected across the forehead. In each there is a conspicuous 

 subapical lobe on the posterior border, and the posterior basal lobe 

 is attached nearer the angle of the mouth than in Euderma or Plecotus.
