38. Eptesicus minutus minutus ( Temminek). 



True to its name, a very small species: total length 2.56 inches (65 mm.), 

 tail 1.15 inches (29 mm.), expanse of wings 7.4 inches (188 mm.). Besides 

 rivalling Pipistrellus nanus in size, it resembles it in color: fur of back and 

 throat bone-brown, but hair of breast with light buffy tips, which increase 

 in length on the belly, until beneath the tail the hair has become nearly 

 white. Flight membranes brownish-black. 



A widely distributed species, extending over a large part of the continent, 

 but represented in our collection by only two specimens, from the northern 

 border of the forested region. At Niangara one was caught after it had flown 

 into a house at night; the other example was shot at Isiro as it flew about 

 in the open, near a dwelling. 



39. Eptesicus garambse sp. nov. 



Despite its larger size, this new species recalls Eptesicus minutus by its 

 brown pelage and brownish black wings. Yet the brown is lighter, for 

 while the fur is deep brownish-black basally, its outer surface on the back is 

 snuff-brown. On the ventral surface the resemblance is closer, the tips of 

 the hair being cartridge-buff. Posteriorly these tips become longer until 

 near the vent the pale color extends to the whole hair. Measurements : 

 total length 3.1 inches (78 mm.), tail 1.27 inches (32 mm.), expanse of wings 

 8.35 inches (212 mm.). 



Our only specimen was collected at Garamba, just on the boundary 

 between the Upper Uele district and the Bahr-el-Ghazal. 



40. Mimetillus moloneyi (Thomas). 



The general appearance reminds one very strongly at first glance of a 

 tiny molossid bat. This is due to its short brown fur, rather broad face, 

 and narrow wings; but a closer view destroys the illusion; the tips of the 

 wings do not fold in, there are no spoon-hairs on the toes, and the tail is 

 entirely included in the membrane. The latter is brownish-black, and so 

 are the wings, as far out as the fifth digit, but from there to the tip they 

 are whitish and transparent. Head, body, and tail measure 3.3 inches 

 (84 mm.), the extended wings only 6.85 inches (174 mm.). 



Mimetillus moloneyi has smaller wings as compared to the size of head 

 and body than any other bat with which we are acquainted (see Fig. 22). 

 Not only the forearm, but the phalanges especially are extraordinarily
