THE FAMILIES AND GENERA OE BATS.

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 Geoffrey. 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.
