the rooms had that peculiar smell noticed beneath the hill at Piaga, where an 

 old-established colony of Nyctinomus ansorgei occupied a narrow vertical 

 cleft. 



Under ordinary conditions it would have been difficult to obtain any 

 specimens; but efforts were being made to dislodge them, by removing 

 sections of the roof; and one day as I stood on the porch, down tumbled 

 two bats. Sprawling on the ground, they were seized before they could 

 climb anywhere to take wing, though they protested vigorously with their 

 sharp teeth. Fortunately they proved to be male and female of a species 

 new to science, M ops osbomi. 



66. Mops (Allomops) occipitalis sp. nov. 



Text Fig. 15 (p. 475). 



When alive and moving this bat recalls at first Nyctinomus ochraceus, as 

 they both have, on the upper side at least, the same dark, rich brown gloss 

 due to their peculiar smooth and soft appearance. But in Mops (Allomops) 

 occipitalis the short hair on the back is restricted to a narrow tract. Where 

 this stops near the base of the hind limbs it ends on either side in a few long 

 hairs, as in many other bats of this genus. Back of the membranous skin 

 uniting the ears the fur is also distinctly longer but forms no crest. 

 Though the flanks are nearly black, the belly is much lighter, either reddish- 

 or buff y -brown. The upper lips are only slightly wrinkled and bear very 

 minute upturned bristles and spoon-hairs. Of medium size, it measures 

 but 4 inches (101 mm.) in length, the dark wings spreading about 10.7 

 inches (272 mm.). 



It lives in hollow trees, and since it was collected only at Medje and 

 Avakubi it may be considered typical of the forest region. The males are 

 exceptionally well represented by seven specimens, whereas among other 

 series of this family females always predominate. 



67. Mops (Allomops) faradjius sp. nov. 



A medium-sized wrinkle-lipped bat of 4.25 inches (108 mm.) in length 

 with the expanse of its dark wings about 12 inches (305 mm.). Since the 

 dark-brown upper side is tipped with gray, it is not so hoary in appearance 

 as the white-tipped back of the larger Mops midas. As in Mops (Allomops) 

 occipitalis the hair, short on the nape, becomes somewhat longer before 

 reaching the membranous skin uniting the ears, but there is no real crest. 

 The dark sides of the neck blend into the nearly white ventral surface,
