formation is found in St. Thomas and others of the Virgin 
islands. It is characterized by shells oi the genera Acte- 
onella , Ammonites , Nerinea &c. 
Mr. Cleve doubts whether the paleozoic Favosites said to 
have been found at St. Thomas and described by Duchas- 
saing and Michelotti is really a production of that island, 
where he found no fossils of paleozoic appearance. Meta- 
m orphic rocks which may however be paleozoic are deve- 
loped in the Virgin islands. 
The paper under notice contains a very full account of 
the rocks and minerals observed, and it is illustrated by 
geological maps of the islands visited by the author.
