REVIEWS, BOOK NOTICES, ETC. 243 



the specific name accepted by " The London Catalogue of British 

 Plants," loth edition. Eight hundred and eighty British plant galls 

 are enumerated in this catalogue, but we fail to see that this number 

 is justified, as we presume that it includes the same gall when present 

 in the stem, leaf, or flower as a distinct gall, and it certainly includes 

 the same fungus when growing on different hosts, whilst the hard 

 woody excrescences so common on our ash trees caused by the 

 fungus Daldinia concetitrica are omitted from the work. The book 

 is well got up, and the numerous coloured illustrations and photo- 

 graphs should make it a useful guide to the identification of our 

 more common plant galls.
