THE FAMILIES AND GENERA OF BATS. 
249 
genus resembles the African Eomops. The peculiarities of the skull 
are, however, more accentuated than in the Old World genus, while 
the lower incisors show no tendency to modification. The outer lower 
incisor is present in the larger species of the genus, but apparently 
always absent in the small M. temminckii. From the American mem- 
bers of the group it is at once distinguishable by the short, flattened 
rostrum with its high lachrymal ridges, and conspicuously for- 
ward-directed antorbital foramina. It is the only genus of Ameri- 
can Molossines with complete premaxillaries, a character readily 
appreciable in young skulls, while even in adults some trace of 
the two palatal foramina usually persists. As I have already stated 
(p. 246) there is no reason to replace Peter’s name Molossops 
by Myopterus Geoffroy. Whatever 
the latter name may apply to, a 
glance at Gervais’s figure of the type 
skull is sufficient to show that Geoff- 
roy’s animal could have not been a 
member of the present group.

Upper incisors short and robust, their form much as in Molossus , 
the height of the crown barely equal to width through posterior 
expansion, the shafts oblique and closely in contact with each other, 
though there is a distinct space between incisor and canine. Lower 
incisors well developed, functional, perfectly in the tooth row, sep- 
arated from each other by a narrow space, but in contact with 
canines, their crowns subterete, with broadly conical cutting edge.
