 Synopsis of British Seaweeds. Compiled from Professor Harvey's 



Phycologia Britannica. 8vo> Price 5 s. Lovell Reeve. 

 Seven years have now elapsed since the publication of Professor Harvey's 

 " Phycologia Britannica," a work which has long been considered indis- 

 pensable to all who desire information concerning the interesting groap of 

 plants which it professes to describe. But, owing to the care which has 

 been bestowed upon its numerous and beautiful coloured illustrations, its 

 price has necessarily been fixed at a rate which must have precluded many 

 from becoming its purchasers. 



Desirous of obviating this, and thereby introducing Dr. Harvey's work 

 to a more numerous class of subscribers, Mr. Lovell Reeve has commenced 

 the publication of " The Atlas of British Seaweeds," which is simply a 

 reproduction of the plates of the Phycologia on a smaller scale. 



The work of reduction has been, on the whole, well performed, although 

 some of the figures, as that of Cystoseira fceniculacea, show the charac- 

 teristics of the species represented less distinctly than they might have 

 been. 



To accompany the Atlas, an abstract of the text of the Phycologia has 

 been published in a separate volume, under the title of the " Synopsis of 

 British Seaweeds." To purchasers of the Atlas, this Synopsis will, of 

 course, be indispensable, but we would also recommend it even to those 

 who possess the " Phycologia." Its small size renders it a convenient 

 pocket volume, and Dr. Harvey has given in the Appendix a new arrange- 

 ment of the British Rhodospermiae in accordance with the views of Pro- 

 fessor Agardh, together with the titles of those Rhodosperms whose names 

 have been altered. 



Since the Phycologia was completed new species of British Algae have 

 been discovered, and an inventory of the latter is given at page 206 of 

 the Synopsis. Descriptions and figures of most of these (by Professor 

 Harvey) will be found in the present number of the Natural History 

 Review.* To the same paper we would also refer the reader for a descrip- 

 tion of Elachista Grevilli, a new species not mentioned in the Synopsis. 



The Atlas is being published in ten monthly parts, two of which have 

 already appeared. When completed, its price (including the Synopsis) will 

 be less than half that of the original work. J. R. G.
