228 The Irish Naturalist. September, 1902. 



as it is coiifiued to Scotland and Ireland. Several Kerr}' localities are 



noted, but there is no hint that it grows also in Counties Antrim, Derry, 



and Down. The following species are not confined to the vSouth as 



might be imagined, but have been recorded also from the North-east, 



thus forming a link of connection between the moss flora of Kerry and 



the west coast of Scotland. 



Fndlania fragilifolia, Taylor. Cephalozia cw-vifolia (Dicks.), Dum. 



ZtyWrz/m J/^r-C-a/zXHook.), Spreng. Pedinophyllum intcrniptum (Nees), 



L. oz'afa, Tayl. Lindb. 



L. hantatifolia (Hook.), Dum. Jungennania bicrenafa, Schmidel.

These are not all the omissions of which we have to complain, but we 

 have not space to point them out. 



The name Jiingennaiiia Lyoni Taylor has been substituted for the 

 ambiguous J. quinquedoitata Web., as " it is absurd to call a plant which 

 has uuiformh' three teeth quinqiiedentata^ "Black Mountains," the only 

 Irish locality for Marsiipclla Fuuckii (Web. and Mohr.), Dum. appears in 

 Moores list, " Black Mountain near Belfast 1837." 



Mr. Pearson's treatment is conservative. We are relieved to find that 

 he has introduced very few new species, and that he has omitted many 

 slight varieties. One w^ould have liked, however, to have heard his 

 reasons for doing so, and why so many of the varieties published in 

 " Carrington and Pearson's Fasciculi" have been passed over without 

 mention, such as Fnillania taman'sci^ar. cornuhica Carr. Scapauia intermedia 

 Husnot and S. piupiirasccns Tayl. MS. have been raised to the rank of 

 species. So also Lophocolea cuspidata Limpr., and Jungerniania soda Nees, 

 a species found in Wales. J. porphyroleuca Nees is united to J. ventricosa 

 Dicks., and the new variety, Whiteheadii, described for a Yorkshire form. 



Nardia silvretta (Gottsche) is described and distinguished from its near 

 neighbour N. scalaris (Schrad.) Gr. & Benn. Most of the gatherings of 

 Pallavieinia hibcrnica (Hook.) Gr. & Benn., are assigned to the var. Wil" 

 soniana (Gottsche) only a few to the type, and a new var. leptodesma 

 Tanslej', is the plant from Malahide. 



A clear and useful key to the genus Fossovihronia has been adopted from 

 Stephani, audit is hoped that the full description and illustrations of 

 Fossombronia, Kiaia, and other neglected genera near the end of our list, 

 now given for the first time in this country, may lead to a fruitful study 

 of the British species. 



It may seem that we have dwelt more on the imperfections than on 

 the merits of the work, and that an Irish grievance has taken up much 

 space. The book is so good we are only disappointed it is not better, 

 and for this the publishers seem more to bl?me than the author. It is 

 a great and laborious work which has now been completed, in which 

 we have the results of the author's lengthened experience and unrivalled 

 knowledge of the British species of a very difiicult, but very beautiful 

 and instructive, order of plants.
