Bibliographical Notices. 349 



Beneden's Eudendrium ramosum appears to us to be different from 

 the species usually so designated, and a new species. The polyp 

 on which Mr. Hassall founds his genus Echinocorium must, we think, 

 be referred to Van Beneden's genus Hydractinia, and is perhaps the 

 same as his H. lactea. 



Such is our hurried notice of this valuable essay, which, it is to 

 be regretted, cannot be procured in a separate form. But we look 

 forward to the time — its object being better understood — when, by 

 means of the Ray Society, essays of this high degree of excellence 

 shall be diffused amongst us widely. 



Mycologia Britannica, or Specimens of British Fungi. 

 By Ph. B. Ayres, M.D. W. Pamplin, 1844. 



This is a welcome addition, especially to the admirers of Epiphyl- 

 lous Fungi, to the various collections of Fungi which have been pub- 

 lished in this. and other countries. It is not at all probable that Mr. 

 Berkeley's ' British Fungi ' will be continued beyond the Fourth Fas- 

 ciculus ; we shall be rejoiced therefore if the present work should be 

 encouraged sufficiently to ensure its continuance, so that it may take 

 its place. The specimens are neatly prepared and correctly named, and 

 we doubt not that in future numbers they will not be so much con- 

 fined to a single division. JEcidium Galiatum, DeC, and ^. ScrO' 

 phularice, DeC, are new to our flora, and J5. pallidum, a pretty spe- 

 cies on Galium Aparine, has been hitherto unnoticed. The specimens, 

 fifty in number, are so arranged that they can at pleasure be trans- 

 ferred to the herbarium. 



PilEPARING FOR PUBLICATION, 



A work to be entitled. Fauna Antiqua Sivalensis, being the Fossil Zoo- 

 logy of the Sewalik Hills, in the North of India. By Hugh Falconer, 

 M.D., F.R.S., F.L.S., F.G.S., and Proby T. Cautley, F.G.S. 



The object of this publication is to make known, in a connected 

 and complete series, the numerous fossil animals which have been 

 discovered in the North of India, by the authors and other inquirers, 

 during the last twelve years ; and to develope the bearings of these 

 discoveries on the physical and geological history of India during a 

 great part of the tertiary period. 



In order to secure to science the full advantage of the Sewalik 

 fossil researches, in a suitable form of publication. Her Majesty's 

 Government and the Honourable Court of Directors of the East India 

 Company have been pleased to accord such an amount of aid in limine 

 as will ensure the successful progress of the work. 



The work will appear in about Twelve Parts, to be published at 

 intervals of about four months, each containing from twelve to fifteen 

 folio plates, or an equivalent number of a larger size where the nature 

 of the subject may require it. The plates to be accompanied by royal 

 octavo letter-press.
