shortened. In the original description (Ann. and Mag. Nat. Hist. (6), 

 VII, 1891, p. 529) Mr. Thomas suggested on this account that its manner 

 of life was less aerial, that possibly it climbed about in search of food on 

 trees or rocks. It is nevertheless our opinion that it probably roosts by 

 day in cavities in trees but that its habits do not differ so markedly from 

 those of other bats. Indeed the stomach contents of a specimen shot during 

 flight at Avakubi consisted wholly of remains of small winged termites, as 

 proved by microscopical examination. It was going at a fair speed and 

 very directly but with rapidly beating wings over the open parade-ground. 

 Whether the manner of flight was due simply to the shape and small area 

 of the wings was not quite clear, for this individual was just recovering from 

 two severe wounds on the shoulder and neck, probably inflicted by that 

 relentless foe, Machwrhamphus anderssoni (p. 552). 



Another example was taken from the stomach of such a hawk, and had 

 undoubtedly been captured on the wing in the usual style, for we had 

 watched the bird, with its mate, in the gathering dusk, as they circled out 

 from a tall dead tree, high over the other tree-tops, returning occasionally 

 to their conspicuous perch. 



First described from Lagos, this rare and peculiar bat is an inhabitant 

 of the forest region, as shown by the localities, Stanleyville, Avakubi, and 

 Medje, from which our specimens come. It is not surprising therefore 

 that it has also been collected on the island of Fernando Po. 



41. Scoteinus schlieffenii (Peters). 



The presence of this small bat in our collection is due to its ardor in 

 following its small prey close up to a lamp, lighting an open veranda at 

 Niangara. 



It is only 3.2 inches (82 mm.) in length and the expanse of the wings is 

 8 inches (203 mm.). Sepia on the upper side and silky white on the lower 

 surface are the predominant colors. Its stout somewhat short-haired body 

 and the short blunt head give it a slight resemblance in form to a molossid; 

 the broadened dark wings, the tiny laterally projecting ears and the tail, 

 supporting the interfemoral membrane to the very tip, are distinguishing 

 characteristics. 



Our specimen is a male. It has a relatively enormous penis, 2 mm. in 

 diameter, clothed with short white hair directed basally and terminating 

 in a pad with a curious escutcheon-like design; the penial bone is 14 mm. in 

 length. Each nostril ends in a smooth slightly projecting pad. Beneath 

 the throat is a small gland opening on the skin by two tiny orifices.
