CONFERVA MYOCHROUS.

binis incurvis. 



In Alpine Torrents at Beddgelert, and the lower regions of Snowdon. Dawfon 

 Turner, Efq. 



FOR the following account of this fpecies, which I believe to be entirely dif- 

 tinct from every other heretofore defcribed, I am indebted to my friend D'awfon 

 Turner, through whofe indefatigable exertions it has been difcovcred, and to 

 whom I am alfo indebted for the drawings A and B. 



" This Conferva, in the month of July laft, was extremely abundant in many 

 of the torrents that flowed from the immenfe mountains which furround the 

 beautiful vale of Beddgelert in Caernarvonfhire : it grew upon their rocky beds, 

 matting the ftones often, to a confiderable extent, with a velvety covering, three 

 or four lines in diameter, which, when taken out of the water, might aptly be 

 compared to the fkin of a moufe. Its color was a dark glofiy brown ; its fubftance 

 foft to the touch ; its filaments fo clofely matted together, as to form almoft an 

 infeparable mafs. Thofe which I was able to detach, were feldom more than 

 half an inch long, but I never was fortunate enough to find any with a root. 

 Examined under a microfcope, their color appeared a pale fubdiaphanous reddifli 

 brown, and there were in fome fpecimens, faint appearances of fepta, but they 

 were no where fo evident as to warrant the inferting them in the figure. The 

 mode of ramification in this plant is very Angular ; fome of the filaments being 

 apparently quite Ample, as in figures C & D. others twice or dirice trunked 

 with patent dichotomies, and, as in figure B. befet with pairs of fnnple incurved 

 acuminated ramuli, arranged almoft entirely on one fide. Thefe latter are fuffi- 

 cient at once to diftinguifh, and indeed die fize of its filaments, which are as fine 

 as the fineft woci, vill always keep it feparate from C. amphibia, die only fpecies
