gazine of Natural History ;' it does not appear to have been ever 

 found by Rudolphi, who has given a description of the species from 

 some specimens communicated to him by Bremser. Bremser found 

 it in but one species, the common cormorant ; I have met with it, in 

 addition to the common cormorant, in the crested cormorant, the red- 

 breasted merganser, and in the red-necked grebe, and Dr. Drummond 

 has found it in the goosander.

XXXIII. — A List of Lichens gathered in different parts of Wales, 

 princip)ally in the neighbourhood of Barmouth, with a few casual 

 observations upon some of the species. By the Rev. T. SxILWEy. 



To Richard Taylor, Esq. 



Dear Sir, Oswestry, Feb. 10, 1844. 



May I request that you will have the kindness to allow me a 



page or two of youi- valuable Magazine to supply a few omissions 



in my list of Welsh Lichens inserted in your January Number ? 



I am, dear Sir, yours faithfully, 



T. Salwey. 



1. Variolaria multipunctata. On trees in the woods about Tyn-y- 

 Gooes, &c. 



2. Endocaypon Hedivigii, /3 lachneum* . In patches about the rocks ; 

 at the angle of the turnpike- road turning down to the harbour 

 between Borthwen and Barmouth, sparingly. 



3. • rufo-virescens, Taylor. On the high wall of the turn- 

 pike-road on the right-hand side leading from Barmouth to Har- 

 lech, just by the first mile-stone. 



This grows not uncommonly upon the walls near Barmouth. It 



* Acharius well observes in his ' Syn.' on this species, that both the colour 

 and the figure of the thallus greatly vary, so tliat it is not to be wondered 

 at that several species have been made out of one. My specimens are of a 

 reddish brown colour and without apothecia. Those which I have received 

 from other quarters, as " lachneian," are of a paler colour, and with nume- 

 rous apothecia. I think the " lachneum " of Fl. Hib. "growing upon rocks 

 in mountain streams " must be a distinct species, as Taj'lor has made it.
