Nycteris aethiopica luteola Thomas. 



This receutly described race from British East Africa is "slightly larger" than 

 typical N. aethiopica ; and as but three external measurements are given by 

 Thomas (Ann. Mag. Nat. Hist., 1901, ser. 7, vol. 8, p. 30), I append the fol- 

 lowing measurements of an alcoholic male, No. 3859, and female. No. 3860, 

 both from Zanzibar: tail, 56, 56.8; ear, 27, 29; forearm, 49, 50.5; thumb, 

 14.6, 15.8; 2d digit, 39, 39; 3d digit, metacarpal, 36.5, 39; 1st phalanx, 25, 

 25; 2d phalanx, 23.8, 26.5; 4th digit, metacarpal, 49, 42; 1st phalanx, 15, 14.3; 

 2d phalanx, 11.3, 11.5; 5th digit, metacarpal, 41.3, 44; 1st phalanx, 13, 13.5; 

 2d phalanx, 12, 13; tibia, 22, 22.6; foot, 11, 11.5; calcar, 19, IS. 7- Another 

 Zanzibar specimen is mentioned by Thomas as the one referred by Dobson (Proc. 

 Zool. Soc London, 1879, p. 718) to N. aethiopica. 



MEGADERMIDAB. 

 Megaderma trifolium E. Geoffrot. 



Two adult males and two adult females were collected by Mr. Thomas Barbour 

 at Tjibodas, Java, in a deep cave called Tjibureum. This cave is at an altitude 

 of about 4000 feet on the slopes of the volcano Pangarango, and it is here that 

 the specimens of Megaderma from this portion of Java are taken, as the species 

 seems to be local in its distribution. The Museum has also a fifth Javan speci- 

 men presented by Mr. Alexander Agassiz some years ago. As the differences in 

 size are very slight, that Andersen aud Wroughton (Ann. Mag. Nat. Hist., 1907, 

 ser. 8, vol. 19, p. 120) have pointed out as characteristic of the Javan animal, it 

 is of value to give the dimensions of those in the Museum collection. 



MEASURExMENTS OF MEGADERMA TRIFOLIUM. 



Lavia frons (E. Geoffrot). 



Two specimens of this genus from Zanzibar seem referable to L. from rather 

 than L. rex. Both are males, in alcohol, Nos. 1138, 1139. In the former the
