of the species which grow in this country, and those which are new 

 or little known. These latter are represented by plates. 

 This work comprehends 80 species ; but the author has intentionally 

 omitted the 28 species collected in South America by MM. Hum- 

 boldt and Bonpland, and described by M. Kunth,

Species Muscorum frondosorum. Edit, a D. Fred. Schwae- 

 GRicHEN, Hist. Nat. Prof. Lips. Pars I. Berolini, 1830. 



r,,,5iv.This is an undertaking for which Professor Schwaegrichen is eminently 

 ,,,..,. qualified. The pupil of the great Hedwig, and possessor of his 

 herbarium, he has the means of determining all his master's species, 

 and having been engaged all his life in adding to the stock of our 

 bryological knowledge, he has accumulated probably the richest 

 mass of materials in existence on his favourite subject. His present 

 , .1. work may be received, either as a distinct production, or as a conti- 

 nuation of Willdenow's Species Plantarum. The first part contains 

 the genera belonging to the families Polytricha, Buxhaumice, Mna, 

 FunaricB, Brya, Lephostoma, and Bartramice. We are glad to 

 perceive, on the part of the author, a disposition to reduce rather 

 than increase the number of species.
