516 LINNEAN society's LIBRARY CATALOGUE. 



thecium. But this short statement must suffice for the present ; 

 for an adequate consideration of these changes — especially the 

 dismissal of Mollia — would lead to a long and intricate discussion 

 of priority which could not be compressed within the limits of this 

 review. Other points to be noted are that Pof/onatum is made a 

 section of Fohjtrichum, and Kntosthodon of Funaria : that Sclero- 

 podium and thjpnum imrwii fall into Brachijtheciiun, Tlhijnchosteiiiinn 

 for the most part into Eurhynchiion, but li. depvessum and E. 

 demissum into Plt(//iotheciuin ; and that Hypmim riujosum is trans- 

 ferred to Hijlocomium. 



Objection should be taken to the names OJigotrichum incurvum, 

 already alluded to, and Heterocladium sguarrosulum, on the ground 

 that the binomials Oli(jotriclnim hercijniauu and Heterocladium dl- 

 morpkum are older, and must be maintained. 



The letterpress has been carefully revised ; misprints are 

 remarkably few, and of these one — "/7, rliri/sopi/lhun," tab. Ivi, 

 fig. L — is a survival from Mr. Jameson's Illustrated Guide. The 

 typography is extremely creditable to the local printer. 



To sum up, the book is an excellent and successful piece of work, 

 and may be cordially recommended to moss-students.

Catalogue of the Library of the Linnean Society of London. New 

 Edition. Burlington House, W. 8vo, pp. 727. Price 10s. ; 

 to Fellows, 5s. 



The Linnean Society cannot be accused of undue haste in 

 issuing this new edition of its Library Catalogue. It is thirty 

 years since the former Catalogue was published, and a few supple- 

 mentary fragments have been printed from time to time. Three years 

 ago a Catalogue of "Periodicals" was printed, of which some 

 copies were distributed ; but the Council wisely withdrew this from 

 publication. In some degree this abortive effort was useful, for it 

 led to the whole question of the Catalogue being raised, and to the 

 arrangement which has resulted in the present handsome volume. 

 As a catalogue jioxir rire it was also not unwelcome in these dull 

 days ; and as the Fellows seem to have taken no exception to their 

 funds having been wasted, there is no need to say much about it. 

 It will doubtless obtain a place in any future collection of " Literary 

 Curiosities " — a position to which its demerits fully entitle it. 



The present Catalogue is a sensibly arranged, and therefore 

 helpful list. Everything is in one alphabet ; the cross-references 

 are sufficient to be useful, without being maddening ; the typo- 

 graphy is good, the binding pleasant to look upon. To country 

 Fellows the book will be a great boon ; and it will, we imagine, lead 

 to a great increase in the borrowing of volumes from the Society's 

 Library, now that folk at a distance from town can ascertain what 

 works are at their disposal. 



Certain little inconsistencies are always noticeable in books 

 of this kind, and the Linnean Catalogue has less than its share. 

 As an example of what is meant, it may be noted that Mr. J. R. 

 Jackson's Guide to the Kew Museum is duly catalogued under
