Preliminary Report upon the Faima and Flora 

 of Plymouth Sound. 



By 

 Walter Heape, IVI.A. 



This Preliminary Report upon the Fauna and Flora of 

 Plymouth Sound is almost entirely composed of lists of 

 species which have been recorded as either actually taken 

 in Plymouth Sound, or common to the neighbourhood. 



The list of Marine Algaj is a reprint of the late Mr. T. 

 Boswarva's catalogue, with a few additions kindly furnished 

 me by Mr. Holmes. 



Mr. C. Spence Bate has been kind enough to prepare a 

 list of Crustacea, and is largely responsible for the information 

 upon that group of animals contained herein. 



Mr. Baker has been good enough to provide a list of the 

 Mollusca of the Sound and neighbouring coast, which has 

 been of great use to me ; while to several fishermen I am 

 indebted for the names of some of the rarer fishes caught in 

 the locality. 



To all these gentlemen I would now express my best 

 thanks.
