coast on the west. I have found it most luxuriantly on the Lizard 

 Head, fruiting freely, and barren at Newquay and Mortehoe, Ilfra- 

 combe and Lynton, in North Devon. On the south coast of Devon 

 it is abundant on the Bolt Head ; occurs sparingly at Sharpstone 

 Point, near Brixham ; and in Dorsetshire I have found it abun- 

 dantly on the Isle of Portland. Like R. fuciformis, Ach., it is 

 only to be found on the sides of rocks sheltered from the wind, or 

 under similar protection, in fissures of rocks. It appears to reach 

 its northern limit at Lynton, where it is very small, and occurs 

 sparingly. It is easily distinguished from R. fuciformis by a 

 pecuharity which I have not seen mentioned in books, viz., the 

 point of attachment of each tuft to the rock is of a dirty yellow 

 colour. This feature is not present either in R fuciformis, nor in 

 any autlientic specimens of R. tinctoria that I have seen. The 

 British records concerning this last named species are incorrect, so 

 far as regards the mainland, and I have seen no specimen from the 

 Channel or Scilly Islands, nor can I find a genuine British speci- 

 men of it in our national Herbaria. R. fuciformis I have only 

 seen in fruit from the Logar Eock, Land's End. When I visited 

 that spot a few years ago, there were hardly any specimens left in 

 fruit. It seems a less hardy plant, although it grows to a larger size, 

 than R. iDliycopsis, since in North Devon it is less abundant than 

 that species. It might be looked for on the west coast of Scotland, 

 since Physica flavicans and Physica leucomela occur at Anglesea, 

 and Lecidea Ralfsii, a Cornish species, has been found in Cumber- 

 land. 



6. Note on Gigartinct Teedii. — This pretty species appears to 

 reach its northern limit in Britain at Torbay, the only spot on which 

 it has been found on the mainland, although tolerably plentiful in 

 Jersey. It grows on a sloping, sandy rock, exposed only at very 

 low tides, and protected from the violence of the waves by a large 

 rock in the water in front of it. It is only where the waves are 

 thus broken that it grows, six yards square being the limit of the 

 area of growth where I found it. In habit it difi'ers somewhat from 

 G. aclcularis which grows near it. The last named species has a 

 creeping habit, rooting along the edges and over the surfaces of 

 sandy rocks, at low water ; but G. Teedii grows in isolated, dense 

 tufts arising from a central point. It has a more reddish tint than 

 G. acicidaris. It has not been found in fruit in England.

 Mr Symington Grieve reported regarding arrangements for 

 summer camp work, and stated that liberty to visit Applecross had 

 been obtained from the proprietor, Lord Middleton.
