cumeut. Our obligations would be much enlarged if the mem- 

 bers of the Club would, in a brief and simple way, tell us where 

 and under what circumstances they find Convallaria Polygonatum, 

 Euphorbia portlandica, Atnmophila arundinacea, Allium olera- 

 ceum, Hieracium prenanthoides, Crepis succisafolia, C. paludosa, 

 Erodium pimpinellatfolium, Gentiana Pneumonanthe, etc. 



It may further be mentioned that the number of phsenogamous 

 species is 810, and the cryptogamous species, mostly Fungi, is 

 somewhat under 400. Many additions will subsequently be made 

 by the members, whose zeal, labour, and success are hereby com- 

 mended, and strongly recommended to the notice of all who are 

 eager to spread useful knowledge.^

 of Desiderata for 1858. 



We have much pleasure in giving publicity to the facts that 

 Thirsk has a Society, organized and in active exercise, for the 

 promotion of Natural History ; and that Greenwich has also a

 things) as they are called. The genus Ranunculus, with its species 

 BabingtoniancB, and its R. reptans elevated a step in this list, cuts 

 a very respectable figure. Draba inflata has also been advanced to 

 specific honours. Its sister brachycarpa is not wanted. The de-

 Rev. C. Clarke, and Mr. W. H. Tug-well were accidentally omitted from the Listof 

 the Committee given in the Preface, and that the Club is indebted to Mr. Gr. B. 

 Wollaston, of Chisleluirst, for much valuable information.
