and its closest Allies. 499 



The general size is as in the Solomon race, markedly smaller 

 than in griseus. 



Type. — J" ad. (in alcohol). Haveri, British New Guinea, 

 700 m., November 1893. Collected by Dr. Lamberto Loria. 

 Presented by the Genoa INCuseum. Brit. Mus. no. 97. 8, 7. 9. 



Range. — British New Guinea: Haveri; Chad's Bay. 



Hipposiderus diadema vicarius, subsp. n. 



Diagnosis. — Anteorbital width as in H. d. piiUatas ; upper 

 teeth 12-1-13-2. Forearm 80-5-85-2. 



Details. — Similar to //. d. imllatus, but on an average 

 larger. The lateral vertical ridges on the front surface o£ 

 the posterior leaf show some tendency to obliteration : in 

 three out of five spirit-specimens from Sarawak they might 

 by a hasty examination rather easily be overlooked. 



Tijxte. — $ ad. (in alcohol). Niah Cave, Sarawak. Col- 

 lected by A. Everett, Esq. Brit. Mus. no. 92. 9. 6. 23. 



Range. — N. Borneo (Sarawak) ; S. Celebes (Kalao) ; 

 Sumatra. 



Remarks. — Six specimens from Borneo, one from Celebes, 

 and one from Sumatra have been examined. The skull of 

 the Celebes individual is in all essential points like those 

 from Borneo (three skulls), only a trifle smaller, with some- 

 what smaller teeth ; the nasal swellings as inflated as in 

 any Bornean skull, the anteorbital width as great as in the 

 largest of these latter. The Sumatra skull is slightly more 

 slender than any from Borneo, the teeth somewhat smaller, 

 the nasal swellings less inflated. These diff"erences, very 

 slight as they are, may eventually, when larger series from 

 these islands are to hand, turn out to be quite individual. 



Hipposiderus diadema, Geoffr., iypicus. 



Diagnosis. — Anteorbital width 9*5-9'8; upper teeth 123- 

 13. Forearm 84-5-91. 



Details. — This form is most closely related to vicarius, but 

 as a rule larger, and Avith the facial portion of the skull 

 slightly broader. The size of the teeth is the same as in the 

 Bornean race. Only skins (six specimens) and skulls (five) 

 have been examined. 



Range. — Java, Timor. 



Technical name. — The species was originally described 

 from Timor *. There is a skin from that island in the
