MAMMALS OF LIBERIA 577 
cavern on the forested hillside, gullied out by stream action in time of heavy rains. 
In the same cavern were two Hipposideros. Our specimen was a female, measur- 
ing: total length 154 mm., tail 79, foot 13, ear 38. 
HIPPOSIDERIDAE Horseshoe Bats 
Hipposideros caffer guineensis Andersen 
Hipposideros caffer guineensis Andersen, Ann. Mag. Nat. Hist., ser. 7, vol. 17, p. 278, 1906: Como 
River, Gaboon. 
Size medium, forearm about 52 mm.; color smoky brown, a horseshoe-shaped flattened nose- 
leaf; width across molars 7-7.7 mm. Como River, west to Liberia. 
Under the name Phyllorhina fuliginosa, Jentink recorded specimens secured 
by Buttikofer and his associates on the Junk and the Du Rivers, and Andersen 
refers three of the specimens recorded by Miller from Mount Coffee to this 
bat. It is larger than the following, which it somewhat resembles. 
Hipposideros beatus Andersen 
Hipposideros beatus Andersen, Ann. Mag. Nat. Hist., ser. 7, vol. 17, p. 279, 1906: Benito River, 
Cameroons. 
Similar to the preceding but smaller, the forearm measuring from 42-44 mm., the tail much 
shorter, 20-22 instead of 27-32 mm., the length of skull about 16.9 instead of 18.5-19.8, the width 
across molars about 6. : 
This species had been confused with the preceding until 1906, when Andersen 
recognized its distinctness and discovered that at least one of those from Mount 
Coffee recorded by Miller as H. caffer, was of the same kind. We secured three 
other specimens, two of which were from the same underground cavern with 
Petalia grandis, hollowed out by torrential rains in the side of a forested hill near 
our camp on the Du. On entering this cavern, the Petalia was first seen, and at 
the sound of the collecting-pistol, the two Hipposideros flew out, one alighting in 
a second small hollow under an overhanging bank, where it was fairly dim, 
though not so dark as in the cavern. The second one flew away into the dimness 
of the forest, but when we returned to the spot the next day, we startled what 
was probably the same individual from the cavern, and it too flew to the identical 
spot under the bank from which we had the day before shot the first one. Evi- 
dently these particular spots were regularly used as resting places. Our third 
specimen was brought in by the natives at Paiata. This is perhaps a somewhat 
solitary species of the forest. 
Hipposideros langi J. A. Allen. Woolly-haired Horseshoe Bat 
Hipposideros langi J. A. Allen, Bull. Amer. Mus. Nat. Hist., vol. 37, p. 434, 1917: Avakubi, Belgian 
Congo. 
A larger species, forearm 66.5 mm., with long woolly hair, sooty, grizzled with pale gray; horse- 
shoe large, with two smaller lappets on each side, a small erect central projection, and a rounded 
shield at the posterior margin of the horseshoe, with a stalked spherical lobule in the middle. Bel- 
gian Congo and Cameroons to Liberia. 
This seems to be another of the forest-dwelling bats of West Africa. Speci- 
mens from the Belgian Congo formed the basis of its description, and the Museum
