a. Q ad. (in ale.). Kila-juc., Eugano; 1891. Collected by Dr. !•:. Modigliani. 



Presented to the Rritish Museum by Mar(|uis (i. Doria (no. 0.12.1.2). 

 Type of the subspecies. 



b. cf ad. (in ale). Bua-Bua, Kngano; 1891. Collector and Donoi- as above 



(B. M. no. 6.12.1.1). 



Similar to H. d. masoni, Init with rather larj^er cars, broader 

 horse-shoe, longer tibia, very Jiroad facial })ortion of tlie skull, 

 and very large teeth. 



The skull of H. d. enganus is (|uite of the ordinary diadema 

 shape ; in size it comes nearest to the skulls of H. d. masotii 

 and H. d. diadema. Tlie facial portion is as })road as, or if 

 anything still ])roader than, in masoni ; in this respect H. d. 

 enganua approaches //. euotis. In all other races of H. diadema 

 known to me the length of the maxillary tooth-row is from 1 1.^J- 

 I ^i.^ nun. ; in the two examples of H. d. enganus it measures 

 \'].'\-\h.''2 mm. — The ears are slightly larger than in any other 

 rac(>: width '^S.;i-!28.8 nun., as against 24.!2-27.') in all otlier forms 

 taken togetlier; also in this respect H. d. enganus approaches 

 H. euotis. Tlie width of the horse-shoe, in all other races, is 

 •.)-li.2 mm.; in H. d. enganus ll.S-12.2 mm. The lower h'g, in 

 seven H. d. diadema and masoni, measures 34.8-35.8 mm.; in 

 two H. d. enganus 3(5. 0-88 nun. The general size (forearm 88.8 

 and '.>2 mm.) is as in //. d. diadema and masoni, if not larger. — 

 In one of the two specimens examined there is a minuti' fourth 

 lateral leaflet, externally to tlie third; a similar indication of a 

 fourth leaflet I have seen occasionally in //. d. incarius. 



H. d. enganus is a well marked local form of //. diadema, 

 so well marked that already a first glance on it (tjje large nose- 

 leaves, large ears, large general size) gave me the impression that 

 it was ratlier diti'erent from any of the races desci'ibed in my 

 j)apei- on //. diadema; but il cainiot be separated as a distinct
