5. pegusa, Yarrell, the Lemon Sole, is occasionally taken with the 

 common species, from which it differs in being rather broader and of 

 a yellowish colour. 



Of the sub-genus Sfonochirus, one species is found on the British 

 coast, and is known by the names Variegated Sole, Red-Backed 

 Flounder, &c. (M. linyttatului'). There are moreover certain Soles in 

 which the pectoral fins are altogether wanting ; they constitute the 

 sub-genus A chinu according to Lacepede.

differ from the Bats inasmuch as the toes of their anterior extremities, 

 which are all furnished with sharp claws, are not more elongated than 

 those of the hind feet, so that the membrane which occupies the 

 interval between the extremities to the sides of the tail can hardly 

 operate in executing more than the functions of a parachute. 

 The dentition, according to Mr. Waterhouse, is as follows :

Cuvier states that the Galeopitheci live on trees in the islands of 

 the Indian Archipelago, and there pursue insects, and perhaps birds, 

 as their prey : judging from the detrition of the teeth with age, he 

 thinks that they must also feed on fruits. They have a very large 

 ctecum. In their teeth they present many analogies to the Lemiirida.
