 Hipposideros diadema (E. Geoffroy). 



An adult female from Sarawak, Borneo, No. 5979, alcoholic, measures as fol- 

 lows : head and body, 84 ; tail, 52; ear, 26.7; forearm, 84.5; thumb, 14 5;

 56.3 ; 1st phalanx, 21 ; 2d phalanx, 20 ; tibia, 33 ; foot, 14.3 ; calcar, 21. Skull :

Hipposideros vittatus (Peters). 



Notwithstanding that this species was described from Ibo Island, Cape Delgado 

 group, three males, Nos. 3297, 3299, 3301, alcoholic, from Zanzibar, seem more 

 nearly allied to it than to any of the other recognized forms of the gigas group, of 

 which it is the smallest member. The forearm and the tibia measurements given 

 by Peters are 105 mm. and 40 mm. respectively, which agree well with the cor- 

 responding dimensions of our specimens given below.
