THE FAMILIES AND GENERA OF BATS. 
197 
Sternum short and broad, its length in middle line not twice as great 
as breadth of presternum ; four or five ribs connected with sternum ; 
ear slightly but evidently funnel-formed Kerivouline, p. 232. 
Sternum slender, its length in middle line more than twice as great 
as breadth of presternum ; six or seven ribs connected with sternum ; 
ear not funnel-formed. 
Presternum with median lobe larger than body of bone ; scapula 
with coracoid straight, directed inward ; second phalanx of 
third finger nearly three times as long as first. 
Miniopterine, p. 227. 
Presternum with median lobe much smaller than body of bone ; 
scapula with coracoid curved outward ; second phalanx of third 
finger not specially elongated. 
Nostrils opening forward beneath a conspicuous horseshoe- 
shaped ridge or low noseleaf Nyctophiline, p. 234. 
Nostrils opening laterally or vertically, the muzzle occa- 
sionally with warty elevations, but never with horseshoe- 
shaped ridge or low noseleaf. 
Seventh cervical vertebra fused with first dorsal ; ear 
with rudimentary keel, but with no anterior basal lobe. 
Tomopeatine, p. 237. 
Seventh cervical vertebra free from first dorsal ; ear 
without keel, but with well-developed anterior basal 
lobe Vespertilionine, p. 197.

G eographic distribution. — Same as that of the family. 
Characters— Sternum slender, its entire length considerably more 
than twice greatest width of presternum; median lobe much smaller 
than body of presternum ; six ribs connected with sternum ; seventh 
cervical vertebra not fused with first dorsal; scapula with coracoid 
curved outward ; nostrils simple, sometimes tubularly elongated, but 
never margined by special outgrowths; lower incisors in all known 
genera 3-3. 
Remarks. — Of the subfamilies of Vespertilionidae this is distinctly 
the most primitive, being perhaps best characterized by the absence 
of the special modifications that distinguish the other groups. 
Principal subdivisions. — The species now known represent 33 
genera.
