3. Peltidea venosa, Ach.? Lich. Univ. p. 514. Engl. Bot. t. 887. 



Hab. Kerguelen's Land ; on tufts of moss on the hills. 



The specimens are in a very unsatisfactory state, being stunted and barren. They, however, closely 

 resemble dwarf Scotch and Arctic individuals of the plant in question, differing chiefly in the smoother thallus 

 and occasional buds. The range of the species is not wide : Lapland and Switzerland are its Northern and 

 Southern European limits. In North America it inhabits the United States, Canada, and the Columbia river. 

 Kerguelen's Land is the only recorded habitat in the Southern Hemisphere. 



4. Peltidea horizontalis, Ach.; LicJi. Univ. p. 515. Engl. Bot. t. 883. 

 Hab. Christmas Harbour, Kerguelen's Land ; on wet moss, abundant. 



Both in characters and in locality the specimens agree with the European P. horizontalis. 



This, again, has not been observed elsewhere in the Southern Hemisphere. In the Northern it is confined to 

 the temperate latitudes, both of Europe and North America, ranging in the latter from the middle United States 

 to Canada, and in Europe from Lapland to Switzerland and the Pyrenees, where it is the only species of the genus 

 inhabiting the top of the Pic du Midi (9,000 feet).

Hab. Strait of Magalhaens ; B'Urville, Hombron. Hermite Island, Cape Horn, and the Falkland 

 Islands ; both varieties on rocks and twigs of shrubs, near the sea. 



This species is also found on the west coast of South America, in Tasmania, Swan River, and the Cape of 

 Good Hope. In the Northern Hemisphere it inhabits the United States and West Indian Islands, the Sandwich 

 group, Great Britain and Ireland, attaining its northern limit at Inverary in Scotland (Lat. 56° N.), which singularly 

 coincides with the latitude of the most southern habitat, namely, Cape Horn. The xax. gilva is certainly only a 

 variety, without the pulverulent lines on the upper surface. The rimae are sometimes white in this species, when 

 it becomes exceedingly difficult to distinguish it from some of its congeners.
