of the original specimens which are still preserved, is a work 

 of considerable difficulty. Such a paper I have long intended 

 preparing, owing to the difficulties I have myself experienced 

 in past years in identifying their plants. 



Two catalogues of the " Hutton Collection " ^ have already 

 appeared. The first, entitled " Catalogue of the Hutton 

 Collection of Fossil Plants, including a Synoptical List of 

 the Chief Carboniferous Species not in the Collection/' by 

 G. A. Lebour, JSTewcastle-upon-Tyne, 1878,^ contains a 

 list of all the specimens then existing in the " Hutton 

 Collection," with appended notes. The second is " A Cata- 

 logue of Fossil Plants from the Hutton Collection, presented 

 by the Council of the Mining Institute to the Natural 

 History Society, 1883, by Eichard Howse." ^ 



This latter catalogue deals only with the specimens in the 

 museum of the Natural History Society, but contains almost 

 all the types and specimens now extant which belonged to 

 the late William Hutton, and thus practically represents his 

 collection. The catalogue also contains notes and references. 

 But in regard to the union of species proposed in this 

 catalogue, in many cases I entirely dissent, as well as to 

 many of Mr Howse's identifications. 



In the following notes I will confine myself to the original 

 work of Lindley and Hutton, and deal only with the speci- 

 mens figured and described by them, and make such 

 observations on their types and original specimens as may 

 be thought necessary ; or, in those cases where the types are 

 lost, my remarks must be confined to their figures and to 

 other specimens which appear to throw light on the 

 subject. 



I take this opportunity of thanking Mr T. Dinning, honorary 

 secretary to the Natural History Society of Northumberland, 

 Durham, and Newcastle-upon-Tyne, for his uniform kindness 

 in giving me every facility for examining the " Hutton
