O74 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Hypsignathus monstrosus H. Allen. Big-lipped Bat 
Hypsignathus monstrosus H. Allen, Proc. Acad. Nat. Sci. Philadelphia, 1861, p. 157: “West 
Africa,’ assumed to be Gaboon. 
Large, forearm 128-137 mm., males larger than females; color above and below sooty brown; 
muzzle greatly enlarged, naked mid-dorsally, the lips with large fleshy folds anteriorly. The West 
African forest region. 
We saw this bat but once, when at dusk in late July a single one, easily 
identified by its large, squarely truncate head, flapped past our camp on the 
Du. Biittikofer found them more common near water, especially in colonies 
in the mangroves, but with the ripening of certain fruits seeking often the high 
forest or plantations to feed on soursops or mangos. It is apparently noisy, 
making known its presence with loud quacks. He mentions specimens from 
the Junk and Du rivers. 
Epomophorus gambianus (Ogilby) 
Pteropus gambianus Ogilby, Proc. Zool. Soc. London, 1835, p. 100: Gambia. 
Similar to Epomops but smaller, forearm in males 87-93 mm., the skull with a long flattened 
rostrum, in which the length of palate is about 2.5 the width outside molars. Back of the canine 
there are three teeth above and five below. Senegal to Nigeria and Abyssinia. 
Although this species is listed by Jentink as having been collected by Biit- 
tikofer on the Junk River, the forearm measurement given (four inches), in- 
dicates that these were probably Epomops. Nevertheless the species doubtless 
occurs in Liberia for Andersen lists specimens in the British Museum from Free- 
town, Sierra Leone, and the Gold Coast. 
Micropteropus pusillus (Peters) 
Epomophorus pusillus Peters, Monatsber. Akad. Wiss., Berlin, 1867, p. 870: Yoruba. 
Size small, forearm about 53 mm., rostrum short and broad, cheek teeth three above and 
five below behind the canine, palatal ridges not forming transverse lines but the first a V-shaped 
ridge, the others incomplete and bordering a central groove; color brown, belly drab, the males 
with white epaulettes and small white tufts at base of ears. Gambia to Loanda, east to the Great 
Lake region. 
Biittikofer secured five females at Grand Cape Mount and Little Gola, 
and Andersen has recorded a specimen sent to the British Museum from Liberia 
by Dr. McCloy in 1908. 
Nanonycteris veldkampi (Jentink) 
Epomophorus veldkampi Jentink, Notes Leyden Mus., vol. 10, p. 51, 1887: Buluma, Fisherman 
Lake, Liberia. 
Similar to the preceding but fur slightly lighter. It is distinguishable by the peculiar characters 
of the skull, in which the tooth row does not extend to near the edge of the orbit, the distance 
from the eye to tip of nostrils is less than breadth at angle of mouth, and the four anterior ridges of 
the palate are transverse. The palate is widely expanded posteriorly. 
Biittikofer was the first to collect this species which so far as known, is charac- 
teristic of the West Coast forest region from Liberia to southern Nigeria. Ander- 
sen in his monograph of 1912 lists but ten known specimens.
