No. 7] REMARKS ON MELOBESLE IN HERBARIUM CROUAN 15 



ters from D. macrocarpum as described by R os an off. Therefore, 

 I propose to name it f. faeroénsis and refer it provisionally to the 

 said spedes, as I at present do not venture to record it a separate 

 species. It forms a link in a group of species whicli are mutually 

 very nearl}/ connected. The limits cannot, however. be decided 

 till old and authentic specimens of D. mam-ocarjnmi have been 

 examined. The form faeroénsis stands on the other hand near to 

 D. Laminariæ, but differs especially as regards the more regular 

 and frequently shorter cells. Also the latter, however, should be 

 more nearly compared with the said species. 



In this connection I beg to remark, that Jlelohesia Corallinae 

 Crn. appears to have been tåken in a vvide sense, probably inclu- 

 ding more than one species. I have not seen any authentic spe- 

 cimen, but on the west coast of Ireland I have collected specimens 

 which are very nearly connected with the last quoted forms or 

 species, with bisporic sporangia. And from the Mediterranean I 

 have seen specimens much approaching if not identic with D. 

 hapaUclioides. Moreover, D. lyustulatam not unlikely also sticks 

 to this host. I do not, however, mention them more precisely 

 until D. macrocarpum is fuUy known.
