and long duration of cold, during the !a>: winter, exercised upon the 

 marine fauna of the coasts of France. 



Sharp frosts, at the time of high tide, would destroy innumerable 

 quantities of animals that the ebb tide would leave exposed. Annelids, 

 Actinans and Fish were found dead or unconscious, paralyzed by the 

 cold. This mortality, strange to say, extended to depths which the 

 change of temperature could not have affected directly. 



Another effect of the cold has been to bring in shore animals ordina- 

 rily seen in deeper water, and also certain species very rare or entirely 

 unknown in our fauna. The Spring was marked by an extraordinary 

 abundance of Balanus porcatus, which covered with a continuous bed 

 the surface of the boulders and rocks, and by the return of the Mussels 

 which had nearly disappeared. During some weeks Mytilus edulis 

 took possession of all the rocks exposed to the southwest wind and 

 formed veritable "moulieres" at Dent, Pointe de Reville and at 

 Draguet. Parallel changes are noticed in the annelid fauna. Thus 

 certain species which were common last year have either become rare, 

 or totally extinct, while new species are continually taking their places.

Preliminary Outline of a New Classification of the Family 

 Muricidae. By F. C. Baker (Bull. Chicago Acad. Sciences, 1895). 

 On reading this paper we regret to find that Mr. Baker has been put- 

 ting his new wine into old bottles. In other words, he has borrowed 

 largely from the phraseology of a conchological paper published in 

 1892, as the following parallel passages show :
