of their wings when they were disturbed. By shooting blindly up into the 

 darkness three specimens were secured, and another was taken by smoking. 

 In spite of these disturbances they returned to this retreat during four 

 months. 



Among six examples captured in late April three were very young, and 

 two gravid females were collected towards the end of January; so February 

 is evidently the month, in the Ituri, during which, they bring forth their 

 young. 



Hipposideros langi is clearly a forest species, and certainly of wider 

 distribution in the Ituri than indicated by our records, though probably 

 reaching its northern limit near the Uele River. 



27. Hipposideros gigas niangarse subsp. nov. 

 Plate LI, Fig. 1. 



Though the distinction of being the largest insectivorous bat of Africa 

 is claimed for Saccolaimus peli, the present subspecies misses it by only a 

 fraction of an inch. In spite of its short tail it measures 5.4 inches in 

 length (137 mm.). The wings when fully extended show a width of 25.6 

 inches (650 mm.). Their long-haired, light brown shoulders are limited 

 on the back by a Y-shaped band of short dark brown hair that reaches for- 

 ward to the white base of the wings, a combination distinctive of this genus. 

 The face and under side are buffy gray. The peculiar nose-lea\ r es, the 

 bristly hairs and sharp-tipped ears are well shown in a photograph (Plate 

 LI) taken from the fresh specimen. 



On the forehead there is a small sac, as in Hipposideros langi, with 

 bristly hairs; but our specimen is a female and shows only a patch of long 

 hairs in front of the vulva. 



This is not a common species in the regions where we collected, for 

 the only specimen we saw flew in under the veranda of a house at Niangara 

 one evening in early June. It had been gorging itself with winged termites, 

 remains of which were still stowed in its capacious cheeks.

 28. Myotis bocagii bocagii Peters. 



This is the smallest of the three subspecies of Myotis represented in our 

 collection. Though nearly adult our specimen measures only 2.75 inches 

 (70 mm.) in length. The color is cinnamon above, light gray below, and
