Appendix I. 



I have thought it best to add in an appendix species 

 recorded by previous collectors which require confirmation, 

 or are almost certainly recorded through mistaken identi- 

 fication. 



Cyanophyce^. 



Bivularia nitida, Kg., recorded by Brady and Talbot from 

 the I. of Man. 



Ghloeophyce^b. 



Enteromorpha granulosa, ? recorded by Marrat from 



New Brighton is not a species of Enteromorpha 

 known to science. 



Bhizoclonium casparyi, Harv., recorded by Marrat from 

 Eastham must be considered as doubtful. Harvey 

 himself was doubtful of its specific value, and Holmes 

 and Batters make it a variety of B. riparium. 



Cladophora rudolphiana (Ag.) Harv. Hilbre I. (Marrat), 

 very doubtful and certainly wants confirmation. 



PHiEOPHYCE.E. 



Litosiphon laminaricB, Harv., is recorded by Marrat as 

 epiphytic on Chorda filum at Bangor and Hilbre 

 I. This species is an epiphyte owAlaria esculenta. 

 Marrat records Alaria esculenta from these locali- 

 ties, but, as I have stated above, I have not been 

 able to confirm his observation. 



Striaria attenuata, Grev., is recorded by Marrat, but he 

 gives no locality. 



Asperococcus bidlosus, Lamx., is recorded by Marrat with- 

 out locality.
