 venusta, on the coast of China ; Littorina scahra and H. squamata, 

 in N. Australia ; H. asininay New Guinea ; and L, mcta., at the 

 Sandwich Islands. 



Red Sea (Erythrcean). 



Of the 408 mollusca of the Bed Sea, collected by Ehrenberg 

 and Hemprich, 74 are common to the Medit., from which it 

 would seem that these seas have communicated since the first 

 appearance of some existing shells. Of the species common to 

 the two seas 40 are Atlantic shells which haye migrated into the 

 Bed Sea by way of the Medit., probably during the newer 

 pliocene period; the others are Indo-Pacific shells which ex- 

 tended their range to the Mediterranean at an earlier age. 



The genera wanting in the Medit. but existing in the Bed 

 Sea, show most strikingly their diTersity of character, and the 

 affinity of the latter to the Indian fauna. 



Other genera become abundant, such as Conus, of which there 

 arc 19 species in the Bed Sea, Cypro^a. 16, Mitra 10, Cerithium 

 17, Pinna 10, Chama 5, Circe 10. 



Persian Oulf. 



The marine zoology of the Persian Gulf and adjoining coast 

 has not been yet explored. * The following shells were picked 

 up on the beach at Kurrachee by Major Baker, with many 

 others evidently new, but not in a satisfactory state for descrip- 

 tion. (1850.)
