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 Pogonatum is made a section of Potytric/mm, and Entosthodon of Funaria ; that Sclero- podium and tiypnum punim fall into Brachytheciiun , WiyJichosteymm for the most part into Eurhynchium, but R, depressum and R. demissum into Plagiothecium ; and that Hypnum rugosum is trans- ferred to Hylocomium. Objection should be taken to the names Oligotrichum incwvum, already alluded to, and Heterocladium squarrosulum, on the ground that the binomials Oligotrichum hercynicum. and Heterocladium di- morphum are older, and must be maintained. The letterpress has been carefully revised ; misprints are remarkably few, and of these one — "ii. chrysopyllum,'" 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. ________ A. Gepp. 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 beiiig raised, and to the arrangement which has resulted in the present handsome volume. As a catalogue pour 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
