HABITS OF ANOMALURUS 463 



Anomah(,rus pell appears, according to Mr. W. H. Adams/ to 

 be a coinmon species on the Gold Coast ; it is coloured black aud 

 white, but iu spite of tire warning which tliis colour should 

 convey, is considered by tlie perhaps rather omnivorous native as 

 " the greatest delicacy." The 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 tliey reascend the tree 

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

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

 stomach. 



Idiurus is a lately-described genus allied to Anoinahirus. 

 There are at any rate two species, /. zcnkeri and /. 'uuicrotls. 

 The thumb is more reduced than in Anomuluras, and the fibula, 

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

 is fused with the tibia below. 



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

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

 differs by the absence of flying membranes. It has, however, tlie 

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

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

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

 AnomaluTus. Tlie thumb has vanished. If we are to compare 

 Anoinalurus 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 Sciums, 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 

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

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