110 ON THE GEOGRAPHY OF ANIMALS. 
are common to both. The more sandy plains of the 
interior furnish but few butterflies, yet present us with 
many carnivorous beetles of a large size, particularly the 
genus Manticora of Oliver. The terrestrial Neuwroptera, 
including the locust tribe, are every where abundant ; 
while the widely spread European Eurymus edusa Sw. 
(fig. 51.) is found at 
the Cape: but, in ge- 
neral, the forms, and a 
few of the species, co- 
incide more with those 
of Asia than of Europe 
or America. . 
(157.) The testace- 
ous Mollusca, or shells, 
have no particular interest ; the continual agitation of 
the sea, and the nature of the coast, appearing unfa- 
vourable to the propagation, or, at least, to the great 
increase, of these animals. The wrinkled ear-shell (Ha- 
liotis Mide L.), with limpets of a very large size, are 
common on the rocks of False Bay ; while the Cyprea 
Algoensis Gray is a very local species. The great 
Achatina Zebra is the largest land shell of this part of 
Africa: but notwithstanding the numerous rivers to the 
westward and eastward, very few fiuviatile shells have 
yet been sent to England. 
(158.) The great tsland of Madagascar may here be 
noticed, as, from its vicinity to the aren continent, its 
productions might be supposed in some degree siniilar’ 
yet this is not strictly the case. The zoology of this 
noble island possesses many very peculiar features, and 
differs more from that of Southern Africa than the 
latter does from the equinoctial countries. It is dif- 
ficult to say, in short, under which of the three great 
zoological provinces in this hemisphere Madagascar 
should be included ; since, although its geographic po- 
sition places it nearest to Africa, its zoology is much 
more akin to that of the Asiatic islands, or even to 
New Holland; at least, such is the inference that may
