proves to be nearly that of the South of Europe, especially of the more 

 southern European islands, as, for instance, Corsica and Sardinia. In 

 a second degree there is a resemblance to that of Northern and West- 

 ern Africa, even as far as the Cape of Good Hope, and in a third degree 

 to that of the coasts of Portugal, France, and England. Some spe- 

 cies are peculiar to the Canaries, though their types exist in Europe ; 

 others have been met with only in isolated points of Europe, Africa, 

 or the Cape de Verd Islands. 



Thus Astrodontium canariense has been gathered in Madagascar, 

 Frullania hispanica in Asturias, Plagiochasma Aitonia in the Ionian 

 Isles, Riccia ciliifera in Portugal, Leptogium Burgessii in Britain, 

 Leptogium ulvaceum in the Marianne Islands, Leptogium Brebissonii 

 in the west of France, Capea biruncinata on the coast of Cape Verd and 

 Chili, Caulerpa clavifera in the Red Sea, and Anadyomene stellata in 

 Brazil, the Mediterranean, and Adriatic. 



The new species described are, Hypnum Teneriffa, Berthelo- 

 tianum ; Hookeria Webbiana, Leptodon longisetus, Glyphocarpus Webbii, 

 Lophocolea Preauxiana, Frullania nervosa, Fimbriaria Africana, Aga- 

 ricus Webbii, Coprinus spiralis, pilulifer, Plutonius ; Cortinarius tri- 

 color, Boletus Preauxii, Clavaria Rhodochroa, Morchella dubia, Pa- 

 tellaria nitida, Phallus canariensis, Polysaccum tinctorium, Puccinia 

 Atropce, pseudosphceria ; JEcidium Atropce, Uredo Frankenice, Kleinia, 

 microcelis ; Evernia scorigena, Ramalina Webbii, decipiens ; Solorina 

 Despreauxii, Parmelia holophaa, Halymenia cyelocolpa, capensis ; Du- 

 montia canariensis, Dasya acanthophora, Polysiphonia myriococca, nu- 

 tans ; Griffithsia Argus, Callithamnion ellipticum, Anadyomene calodic- 

 tyon, Conferva pachynema, enormis ; Lyngbya ? cantharidosma, Chroo* 

 lepus ianthinus, Rivularia cerebrina, monticulosa. 



The greater part of these species, and some 6thers not absolutely 

 new, are illustrated by the most admirable figures, as are also two 

 new genera of Algae, Capea and Asparagopsis ; nor must we forget to 

 notice the admirable analysis of Caulerpa. A species closely allied to 

 Anadyomene calodictyon has been raised to the rank of a genus by 

 Decaisne, under the name of Microdictyon. On this subject the au- 

 thor remarks in a letter lately received, " Nul doute que son Micro- 

 dictyon ne soit un bon genre, reste a savoir si mon Anadyomene calo- 

 dictyon peut y entrer sans modification des caracteres. Notez que 

 Decaisne dit positivement (et cela est vrai pour Y Hydrodictyon umbi- 

 licatum d'Agardh), qu'il n'y a aucun trace de ces cellules disposers 

 en evantail qui distinguent Y Anadyomene. Or Y A. calodictyon est par- 

 faitement intermediate en ce qu'il presente ces veines regulierement 

 flabellees et qu'il est depourvu de la membrane que les relie entre 

 elles. ; Ou il faut modifier les caracteres generiques du Microdictyon, 

 ou il faut faire un troisieme genre."
