all corniculate (the habit being exactly that of 8. linita, Ach., see Delise's figure), and the consistence is much thin- 

 ner. Laurer's synonym may be regarded as tolerably certain ; the description agrees, and a specimen of the plant 

 collected by Sieber (named 8. damatcornis), whose Lichens Lamer describes, is found in the Hookerian Herbarium. 

 The various forms of this species occur commonly in the subtropical, temperate, and frigid regions of Australia, 

 South America, and their outlying islands. I strongly suspect that Menzies' specimens of S. anthraspis came from 

 New Zealand, and not from North America. If it were worth while, twice as many varieties might be enumerated, 

 and very probably several species of Delise and Laurer should be added to the synonyms.— -Plate CXXIV. Var.

Very similar to S. damacomis in its ramification, and, like it, prone to considerable variation, as is apparent from 

 the few specimens which I have examined. The consistency of the thallus, however, is widely different, and is so 

 extremely brittle that most of the specimens are more or less mutilated. The central costa being more or less dis- 

 tinct, is likewise a character of importance. The var. /3 cannot be satisfactorily separated ; the lobes are broader 

 and shorter, and the colour is different ; the under side likewise is sometimes, but not always, quite smooth. S. , 

 comis, var. rufa, Bab. in Seemann's Bot. of the Herald, hied. (S. rufa, Auctt.) is an analogous form of S. 

 I am indebted to Dr. Fenzl, of Vienna, for a minute specimen of 8. glaberrima, Laur. ! which (when compared with 

 the description) I have no doubt in referring hither. Laurer gives the Mauritius as the habitat, but my specimen 

 is marked as from New Holland. In all likelihood 8. cimiamomea, A. Rich. II. de la N. Zel. p. 28.pl. 8,/. 3. is 

 a fine state of this form. It does not seem, however, to be costate ; the apothecia are represented as very dark, 

 and having a tolerably broad margin. I have seen no authentic specimens.
