CHAF. XXIV.] THE BABOON-MONKEY. 55

 overlooked. It is the same species that is found all 

 over the forests of Celebes, and as none of the other 

 Mammalia of that island extend into Batchian I am 

 inclined to suppose that this species has been accidentally

 have been very recent, as • in a fertile and unoccupied 

 island svich an animal would multiply rapidly. The only 

 other mammals obtained were an Eastern opossum, which

 Hying opossum, Belideus ariel ; a Civet cat, Viverra 

 zebetha ; and nine species of bats, most of the smaller 

 ones being caught in the dusk with my butt-erfly net as 

 they flew about before the house.
