Throughout the following catalogue of the mosses, the zones 
which each species occupies will be distinctly specified ; and to 
enable me to do this in the smallest possible compass, I propose 
the notation of zones above indicated, that is to say, Z, for the 
first zone above the plain, Z, for the second, &c., and Zi for the 
plain itself. It is in many cases difficult to ascertain the zoné in 
which a moss has normally its station, for in mountainous coun- 
tries the seeds, &c. of mosses are carried down by the streams, 
precisely as those of flowering-plants are ; but a large proportion 
of mosses are found only near streams, and that especially in a 
low latitude, where the requisite degree of moisture is more rarely 
met with. Hence certain mosses, “natives of the alpine region, 
are occasionally found some thousands of feet below it. To take 
an instance in Grimmia spiralis, a species which is stated by the 
authors of the ‘ Bryologia Kuropea’ to have its “ véritable habitat 
au-dessus de toute végétation forestiére.” Near Cauterets, op- 
posite the baths of La Raillére, on the rude blocks of granite 
which are thickly strewn along the banks of the Gave de Marea- 
daou, this species forms large lax tufts, disfigured by the sand of
