AND ADJACENT WATKES. 305 



usually monosporous sporangia in the position in which Harvey 

 nearly fifty years ago suggested, and in the cortex too. I hope to 

 publish shortly a detailed description. 



Bighury Bay. 



The rocks south of Yealm River mouth towards Stoke Point, fully 

 exposed to the south-west gales, were generally barren like those 

 between Rame Head and Penlee Point. East of Revelstoke Point, 

 and well protected by it, there are good, well-stocked rock-pools. A 

 short visit to the pools west of Revelstoke Church led me to think 

 the weeds generally comparable to those found on the Renny Rocks, 

 Wembury Point, and the Mewstone. Cystoclonium pw'purascens, 

 8arcophyllis edulis, Monospora, Gri^thsia equisetifoUa, Ptilota 

 elegans, Mesogloea vermiforniis, and many others were seen. The 

 dredge brought up PhyUop)liora ruhens with nemathecia, Spondylo- 

 thamnion muUijida, Antithamnion plumtda, Bonnemaisonia aspara- 

 goides, Dictyopteris polypodioides, Sphacelaria Jilicina, &c. 



I propose in a subsequent number of the Journal to continue my 

 observations on the flora, to give a more detailed list of the species 

 met with, and to trace out the distribution, in the different localities, 

 of individual species. I have, I trust, said enough to show that 

 there is no lack of algae needing investigation. It is impossible for 

 me to give an adequate idea of the details of the flora. I shall be 

 only too pleased to place my knowledge, gained under such great 

 advantages, at the service of algologists.
