List of Specimens. 



SYNOTUS, Ketserling & Blasius. 

 Synotus, Ketserling & Blasius, Wiegm. Archiv fur Natarg. 1839. 



Ears very large ; outer border extended anteriorly as far as 

 the tragus ; large excrescences on either side of the nose con- 

 tinuous with the inner border of the ear ; semicircular fold on 

 the base of the outer border of the ear ; no tongue-shaped 

 appendage at the base of the inner border, as in Plecotus. 



The genus Synotus, as represented by Keyserling & Blasius, 

 includes both the species found in the United States. It is 

 closely allied to Plecotus (a European genus), as both are to 



Vespertilio.
