To the names of such species as have beeu recently added to the 

 British flora, the name of the observer is added. 



It will be seen that the number and variety of species is considerable, 

 yet, as we have found it in all other localities in the summer or autumn, 

 of ISoo, smaller than usual. The species are, with very few exceptions, 

 such as belong to fresh water ; for the only forms that belong to 

 brackish or sea water are Navicula elegun.^, Pinnularia jieregrinay 

 and perhaps Synedra acicularis. 



There are one or two forms, which, although I have described them 

 as occurring in the Glenshira sand, are yet more frequent in some of 

 these gatherings than I have seen them elsewhere. Such are Cocconeis 

 transversulis, which I have also found in other freshwater gatherings ; 

 and Tnjhlionella apiculata, figured in the paper I lately read to the 

 Royal Society of Edinburgh. The rest of the forms, with the ex- 

 ception of those marked with my name, and one or two others of 

 Ehrenberg's, are such as have long been known, and are very frequent. 



MISCELLANEOUS. 



KDWARDSIA VESTITA (fORBES). 



One of the most interesting additions to our native zoophytology 

 that has been made for some time is a species described by the late 

 Professor Edward Forbes under the above title from specimens found 

 by him on the island of Paros in the -lilgcan Sea* . It is a vermiform 

 Actinia some si.v inches in length, with a beautiful expanded disk of 

 spotted tentacles ; the most conspicuous jdisenomenon in its CEConomy 

 being that it inhabits a tough thick tube formed of condensed mucus, 

 which is secreted in great abundance and thrown off from the surface 

 of its body. 



This curious and beautiful zoophyte has been procured in some 

 nunjbers by Mr. W. A. Lloyd from the coast of North Wales ; and

 1S43.
