already referred to, are also confined to the West African 

 Sub-region. 



Turning now to the Carnivores, there are found in the 

 West African Sub-region only, two remarkable genera, 

 Poiana and Nandinia. Of these the former is closely 

 allied to the genus Prionodon, a beautifully marked civet- 

 like little animal of the Oriental Region, and the latter is 

 akin to the Palm-civets (Paradoxurus), also found in the 

 Oriental Region, but not in Africa. 



There is only one genus of the Insectivora confined 

 to this Region (Potamogale), already alluded to as being 

 probably allied to the Madagascan Geogale. This much 

 modified form is one of the few members of the Insectivora 

 that has adopted aquatic habits. It is, for a member of 

 the order, of considerable size. 



The Bats of West Africa, as is usually the case in 

 every land, belong mostly to widespread forms. Out of 

 sixteen genera only two, each containing a single species, 

 are confined to this Sub-region, while a third (Epomophorus) 

 has not been found outside Africa. These three genera all 

 belong to the family Pteropodidte, which contains the large 

 fruit-eating bats. A few species of Lemurs still survive in 

 the forests of the West African Sub-region. They belong 

 to two genera, neither of which is represented in Mada- 

 gascar. Of these, one (Oalago) is also found in the other 

 parts of Africa ; the other (Perodicticus), containing two 

 species, is met with only in the West African Sub- 

 region. 



The forests of West Africa are plentifully supplied 

 with Monkeys. Most of these belong to the genus 

 Cercopithecus, of which, out of about forty species, 

 thirty are met with in West Africa. Another enus,
