Od some Maminals from Eogano Island, West of Sumatra : bj oldfield thomas, 

 British Museum. 



By the kindness of the Marquis G. Doria I have been en- 

 trusted with the examination of a small collection of mammals, 

 chiefly bats, obtained by the well known and successful explorer 

 Dr. E. Modigliani in the little island of Engano , west of Su- 

 matra, the birds and reptiles of which have been already worked 

 out by Salvador! (*) and Vinciguerra (^). In view of the inte- 

 resting discussions of these authors on the relations of the Engano 

 Fauna , it is unfortunate that the mammals , usually so helpful 

 in this respect, are not of a nature to throw much light on the 

 subject, being for the most part very widely distributed Malayan 

 forms. The new Pteropus however, on whose discovery Dr. Mo- 

 digliani is to be congratulated, confirms the interesting relation- 

 ship already pointed out as existing between Engano and the 

 Andamans and Nicobars on the north, and Christmas Island on 

 the south, as it just connects species found in these islands , 

 while no allied form is as yet known to occur in Sumatra. 



1. Paradoxurus hermaphroditus. Pall. 



a. Pulo Dua, July 1891. 



Dr. Modigliani states that this is the only Carnivore found 

 in the island. 



This individual presents the interesting peculiarity of having 

 five right lower premolars, an extra tooth, smaller than p^ 

 and larger than p^ , being inserted between these two teeth.
