TARSIUS 9 



1910. Cabrera, in Annals and Magazine of Natural History. 



In this paper reference is made to Lemur tarsier Erxl., which, 

 it is stated, must be taken instead of Tarsius spectrum Pallas 

 as the name of the species, the Author evidently not being 

 aware of the fact that Erxleben's species, and also that of 

 Pallas both founded on BuiTon's animal, are quite undetermi- 

 nable and therefore both names must be dropped. 



GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. 



The members of this genus are found on the islands of the East 

 Indian Archipelago. Seven species have been described, of which two 

 are not yet satisfactorily established. In Borneo we have T. bornea- 

 Nus, its range unknown; in Billiton Island T. s.\ltator is found, and 

 it may probably occur in Banka and Sumatra. In Java T. bancanus 

 was met with ; Celebes has T. fuscus, and in the Philippine Archi- 

 pelago T. PHiLippiNENSis occurs on Samar, Leyte, and Mindanao, and 

 T. sANGHiRENSis on Sanghir. It must be considered, however, that 

 the dispersion of the Tarsier is as yet but very imperfectly known, and 

 many other islands probably possess those above named, or contain 

 species not yet discovered. There is no large series of these animals in 

 any collection, and specimens are very much needed for study and a bet- 

 ter understanding of the group. T. fraterculus was taken on Bohol.
