Liberia ^^ 



Occasionally in the human species there is a reversion to this 

 condition ; tor women are known to develop rudimentary, non- 

 functional mammas on the abdomen, similar to the third pair 

 ot non-tunctional teats on the udder of oxen. 



The Galagos also utter loud cries at night, and are chiefly 

 nocturnal in their habits, being sleepy and unwilling to move 

 in bright daylight, at any rate until they become thoroughly 

 tamed. They will otten move about a house during the day- 

 time because they are sheltered from bright sunlight, which they 

 dislike. I have not observed in the Liberian type of Galago 

 that tendency to make use of the hands as weapons of offence 

 which is so marked in some of the larger forms of galago in 

 East and South Africa. These will stand erect on their hind 

 legs and box like a man. In fact, they defend themselves with 

 their hands quite as much as with their teeth against aggression 

 on the part of a dog or cat, delivering blows with the 

 knuckles as well as " pulls " and snatchings. Like some other 

 lemurs, the galagos resort a good deal to bipedal progression, 

 running, walking, and jumping on their hind-legs in a nearly 

 upright position, and reserving the hands for offence and 

 defence. With a quick, darting motion of the hand whilst 

 progressing on their hind-feet they will seize insects. The 

 human principle of locomotion on the hind-limbs began far back 

 amongst the lemuroids, many of the monkeys and apes having 

 reverted to a quadrupedal movement. 



Bats are very abundant in Liberia. The Fruit-eating forms 

 (^Megachiropterci) are represented by Hypsignathus and four 

 Epomophori, by two or three species of Roiissettus,^ and by at 

 least one brush-tongued bat — Megaloglossus. 



' The older name, Roitssettus, has recently been revived (unhappily, because 

 of the law of priority) in lieu of Xantharpyia. Biittikofer's, or rather Jentink's 

 Leiponyx, given to one doubtful Liberian specimen from which claws on the index 

 fingers were accidentally absent, is not now admitted without further evidence.
