HABITS OF ANOMALURUS 463 



Anomalurus iicli appears, according to Mr. W. H. Adanis,^ to 

 be a conimou species on tlie Gold Coast ; it is coloured black and 

 white, but in spite of tlie warning wliich this colour should 

 convey, is considered by tlie perhaps rather omnivorous native as 

 '•■ the greatest delicacy." Tlie animal is nocturnal, but affects only 

 bright moonlight nights. Their " flying " consists of a jump from 

 a high branch to a lower one, after which they reascend tlie tree 

 to a point of vantage for another jump. They are said to feed 

 upon nuts ; but Tullberg only found tlie remains of leaves in the 

 stomach. 



liliurns is a lately-described genus allied to AnotiKduras. 

 There are at any rate two species, /. zcnkeri and I. viacrotis. 

 The thumb is more reduced tlian in Anomalurus, and tlie fibula, 

 contrary to what is found in that genus and in most Sciuromorphs, 

 is fused with the tibia lielow. 



A third genus, very recently described and allied to both the 

 foregoing, is Aethurus. It is a native of the French Congo,^ and 

 (lifters by the absence of flying membranes. It has, however, the 

 pad of large scales. There is but one species, A. glirimcs. It 

 has a black bushy tail. The postorbital processes of the frontals 

 are totally wanting^ — there are not even the traces to be seen in 

 Anomalurus. The thumb has vanished. If we are to compare 

 Anomalurus with the Squirrels then, thinks Mr. de Winton, the 

 present genus is probably diurnal by reason of the want of flying 

 membranes. 



Fam. 2. Sciuridae. — The Squirrels, genus Sciurus, are world- 

 wide in range, the Australian region and the island of Madagascar 

 being alone excepted. 



The eyes and the ears are large ; the tail is of course long 

 and bushy. The fore-feet have an inconspicuous thumb ; the 

 hind-feet have four toes. The soles of the fore-feet are 

 naked or furry, those of the hind-feet are hairy. There are 

 twelve or thirteen dorsal vertebrae, and in correspondence seven 

 or six lumbars. The caudal vertebrae may be as many as twenty- 

 five. In the skull the frontals are broad, and there are long
