silvery suffusion ; hair of the nape and upper part of the head 

 basally pale ecru, which tint shows through the general color, pro- 

 ducing a lighter appearance in those regions. Lower surface 

 wood-brown, becoming ecru on the sides and flanks. INIembranes 

 hair-brown. 



Measurements. — Type (collector's measurements): "Length, 

 90;'" tail vertebrre, 28; alar expanse, 373; finger (longest), 90; 

 head, 17; forearm, 56 mm." Average of thirteen alcoholic speci- 

 mens: Length of head and body, 58.8 mm.; head, 16.7; ear, 15.9; 

 tragus, 6.3; forearm, 53.3; thumb, 7.6; third finger, 93.1; tibia, 

 21.6; calcaneum, 21.8; foot, 9.5; tail, 25.8. 



Remarl-s. — This form can readily be distinguished from typical 

 merjalophjlla and m. intermedia by the form of the second upper 

 premolar. Its distribution seems to coincide with the tableland 

 of j\Iexico (and its more northern remnant), though two specimens 

 from Tampico are perfectly typical. 



Specimens Examined. — Seventeen — two skins, thirteen alcoholics, 

 two skulls — all from the United States National Museum : 



Fort Clark, Tex. (1). 



Tampico, Tamaulipas, Mex. (2). 



Guanajuato, Guanajuato, Mex. (1). 



Mirador, Vera Cruz, Mex. (8). 



Orizaba, Vera Cruz, Mex. (2). 



Morelos, Mex. (3). 

 Mormoops megalophylla intermedia (Miller).

Type Locality. — Cave at Hatto, north coast of Curacao, West 

 Indies. Type, adult female, No. 102,174 Coll. U. S.' National 

 Maseum. 



Distribution. — Apparently limited to the island of Curacao, 

 where it frequents ' ' caves and rock crevices in all parts of the 

 island. ' ' 



General Characters. — Differing from typical megalop)hylla in the 

 smaller general size, and the greater size and general cro.wded con- 

 dition of the first upper premolar. 



Teeth. — Essentially as in M. megalophylla, but differing in the 

 thicker and heavier first upper premolar, which tooth is crowded 

 " This without doubt includes the tail.
