somewhat northern character, 50 per cent. of them being com- 
mon to Norway, and 86 per cent. common to the south of Spain. 
On the southern coast of the Peninsula 353 species were 
obtained, of which only 28 per cent. are common to Norway and 
51 per cent. to Britain. 
The identical species are chiefly amongst the shells dredged 
from a considerable depth (35—50 fathoms) ; the littoral species 
have a much more distinct aspect. 
The shells of the coast of Mogador are generally identical 
with those of the Mediterranean and Southern Peninsula. 
Canary Islands. The shells of the Canaries collected by MM. 
Webb and Berthelot,* and described by M. D’Orbigny, amount 
to 124, to which Mr. M‘Andrew has added above 170. Of the 
300 species 17 per cent. are common to Norway, 32 per cent. to 
Britain, and 63 per cent. to the coasts of Spain and the Medi- 
terranean. ‘Two only are W. Indian shelis, Neritina viridis and 
Columbella cribaria. Of the African shells found here, and not 
met with in more northern localities, the most remarkable are :— 
Crassatella divaricata. Ranella levigata. Cymba, proboscidalis. 
Cardium costatum. Cassis flammea. Conus betulinus.

Madeira. Mr. M‘Andrew obtained 156 species at Madeira, of 
which 44 per cent. are British, 70 per cent. common to the 
Mediterranean, and 83 to the Canaries. Amongst the latter 
are the two W. Indian shells before mentioned, and the follow- 
ing African shells :— 
Pedipes. Mitra fusca. Patella crenata. 
Littorina striata. »  Zebrina. »  guttata. 
Solarium. Marginella guancha, _y,  Lowei. 
Scalaria cochlea. Cancellaria. »  Candei. 
Natica porcellana. Monodonta Bertheloti. | Pecten corallinoides. 
Azores. Amongst the littoral shells which range to the 
Azores, are Pedipes, Littorina striata, Mitra fusca, and Ervilia 
castanea; the other species obtained there are Juusitanian.

The Mediterranean fauna is known by the researches of Poli, 
Delle Chiaje, Philippi, Verany, Milne-Edwards, Professor H. 
Forbes, and Deshayes. In its western part it is identical with 
that of the adjacent Atlantic coasts; the number of species 
diminishes eastward, although reinforced by a considerable
