NOTE, 



In preparing a list of the Mosses, so short a time after the publication of the " Flora ol 

 Liverpool," by Dr. Dickinson, some explanation appears necessary. 



At the close of the year 1851, the number of species known to our local collectors was 114 ; 

 and at the end of the year 1854, the species numbered 170 — shewing an increase of 5fi, or nearly 

 one half of the original number. 



Among these will be found three new British species, two of which are new to the science, 

 (Bryum cochlearifoUum and Bryvm Marratii J and the third (Brytim calophyllumj was enveloped 

 in considerable obscurity on account of the ambiguous descriptions, and the want of good fruiting 

 specimens for examination. If we add the following rarities, Hypiium elodes, polyijamum or 

 itodijioi'inn ^ scorpioldes, piUfm^tmy resupinatuitiy pratense^ ccespitosum^ eJcgans, salebrosuvt, 

 Kneiffii, pitmUum ; Omalia trichomanoides ; Meesia nliginosa ; Leskea polycarpa; Campylopus 

 terfacetis ; Splachnuvi ampullaceum ; Orthotrichum teneUvm , phyllanthum, &c., it will be found 

 that our list is equal in interest to any hitherto published, and vastly superior to most. 



My thanks are due to those gentlemen who have contributed to this paper. Mr. Harrison 

 and Mr. Fisher have each furnished me with a list of localities, and some interesting additional 

 species. 



Dr. Dickinson, with his usual urbanity, has greatly assisted me by lending books, &c., from 

 his extensive and very valuable librai^, without which my operations would have been materially 

 diminished and my progress retarded. 



William Wilson, Esq., of Warrington, has been the principal means of our receiving such an 

 extraordinary increase to the list ; his able assistance has been given on a great many occasions 

 where uncertainty would otherwise have caused the specimens to have been thrown aside. 



Mr. Tudor, of Bootle, whose love of Natural Historj', and particularly of Botany, has led him 

 to investigate some of the most important facts connected with the science, has always been ot 

 great service. Mr. Sansom and Mr. Shepherd must not be omitted.
