different in the two districts. In Madagascar we have Opolemur, 

 Microcebus, and Chirogale ; on the continent, Galago. The 

 members of this sub-family have markedly large ears, which are 

 but little furry; the tail is long. A very marked skeletal 

 character distinguishes this sub-family from other Lemuridae, 

 and allies them to Tarsius, that is the lengthening of the 

 calcaneum and naviculare in the ankle. The dental formula is 

 as in Lemur. The supporting bands of the caecum are in this 

 sub-family as in the genus Lemur. There are but two folds, of 

 which one is median and non-vascular; the lateral fold bears a 

 blood-vessel, and is joined by the median frenum. The brain is 

 but little known. The only figure of the brain of Galago is one 

 by myself. There are four mammae, two on the breast and two 

 upon the abdomen. 



The genus Galago comprises at any rate six distinct species. 

 They are all African, and range right across the continent from 

 Abyssinia as far south as Natal, and to Senegambia in the west. 

 The incisors of the upper jaw are small and equal ; there is a 

 gap between the canine and the first premolar. The molars and 

 the last premolar have four cusps ; the last molar of the lower 

 jaw has an additional fifth cusp as in Macacus, etc. The Galagos 

 are chiefly nocturnal, and are more or less omnivorous. Owing 

 to their long hind-legs these animals when they leave the trees 

 advance upon the ground by hops like a Kangaroo. Galago 

 senegalensis makes a nest in the fork of two branches, where it 

 sleeps during the day. The Great Galago (G. crassicaudatus) is 

 named by the Portuguese " Eat of the Cocoa-nut Palm." Sir 

 John Kirk, after whom a variety of this species is called, relates 

 that it is incapable of resisting the fascinations of palm wine, 

 upon which it will readily intoxicate itself, and as a consequence 

 brave probable captivity. I have referred above (p. 536) to the 

 patch of spines upon the tarsus of G. garnetti. 



The genus Chirogale is entirely confined to Madagascar. It is 

 to be distinguished from Galago by the fact that the inner incisors 

 are larger than the outer. There are five species of the genus 

 known : four previously to Dr. Forsyth Major's recent visit to 

 Madagascar, and a fifth brought back by him. 1 In connexion 

 with this genus the naturalist just mentioned has observed 

 that all the Lemurs of Madagascar, including the aberrant
