A Manual of the Land and Fresh-water Shells of the British 

 Islands, with coloured Plates of every Species. — This is the title of 

 a work lately published by Dr. Turton, author of the Concho- 

 logical Dictionary. Collectors of land and fresh- water shells 

 will receive great assistance from this beautiful and accurate 

 volume, in the arrangement of their shells. It is to be regret- 

 ted, however, that it tends to continue the delusion about these 

 testaceous coverings, as if their beauty and scarcity were the 

 main objects of the study; and not the structure,, faculties, and 

 habits of the animals that lived in them. 



Discovery of a Reef in the PaciJlc.-r^A. dangerous reef has been 

 discovered in the Pacific ocean, among the Caroline Islands, the 

 N. E. extremity of which is in latitude 7° 36' N. and longi- 

 tude 155° 18' E. It was found to lie in a N. E. and S. W. di- 

 rection, and is so extensive, that the whole of it could not be 

 seen from the N. E. extremity. It is about fourteen miles in a 

 W. S. W. direction from Island Bordelaise, discovered in 1826. 

 The discovery is due to the ship Larkins, W. Campbell, master ; 

 and, as here given, is extracted from her log, bearing date 23d 

 February, 1830. — Jour. Royal Geo. Soc. of Lofidon, 1830-31.
