MARINE ALG^ 

 The coast of Kent, owing to the geological character of the cliffs, is not remarkable for 

 rock pools, and consequently a large number of species of marine algse found on the rocky western 

 coast of England in much the same latitude have not been found in this county. But 

 only a comparatively small portion of the coast has been explored by algologists, with the 

 exception of the neighbourhood of Deal by Mr. J. T. Neeve. His search was rewarded by 

 the discovery of three species, new not only to the British Isles, but to science, viz. Neevea 

 repens, Batt. Erythropeltis discigera, Schm. var. Flustres, Batt. and Gonimophyllum Bu-ffhami, 

 Batt. Rhodynienia corallicola, Ardiss., aiiother species new to this country, has as yet only 

 been found in Kent. The neighbourhood of Folkestone has been examined at intervals by 

 Mr. J. Cosmo Melvill, that of Sandgate by Mr. E. M. Holmes, that of Chatham by Dr. J. W. 

 S. Meiklejohn, and that of Margate by the late Mr. T. H. Buffham. The list at present 

 includes rather less than one-third of the known British species, but it is quite probable that 

 a careful search near the mouth of the rivers Thames and Medway, and on the coast of Romney 

 Marsh might add considerably to the number, especially of the Cyanophycece and Chlorophycecs.
