PRE FACE. 



The Editor has to thank the subscribers for their support and 

 the contributors who have co-operated in the production of the 

 present volume. Changes in the staff have been made. We 

 have to mourn the decease of Mr. Charles P. Hobkirk, who 

 has been so intimately associated with natural science and 

 particularly with ' The Naturalist ' for a great number of years. 

 During the years 1864 to 1867 he was virtually its sole Editor, 

 and from 1875 to x 884 he edited it in partnership with Mr. 

 George T. Porritt. 



Of papers in the present volume mention may be made of the 

 descriptions of species of Fungi New to Science, the important 

 article with plates of Harpidioid Hypna, and the Catalogues of 

 Birds of Yorkshire and Lincolnshire and of Lincolnshire Non- 

 Marine Mollusca, as being of more than local importance and 

 appealing - to a circle wider than that of the northern counties. 

 The moss-paper embodies the fruits of important recent re- 

 searches, the bird-list is the only one published in Britain 

 strictly in accordance with the law of priority as to nomenclature, 

 and the molluscan list is the first to set forth in Britain the 

 views of modern malacologists as to the sequence of the species. 



So much for the current volume. 



There now remains for the Editor to announce that with the 

 present number comes to an end his responsibility for a journal 

 which he has either alone or in alliance with others conducted 

 for eighteen years and a half. The volumes from August 1884 

 to the end of 1888 were edited in conjunction with Mr. W. 

 Eagle Clarke, now of the Edinburgh Museum, and that for 1892 

 in partnership with Mr. Edgar R. Waite, now of the Australian 

 Museum at Sydney, each of whom was a colleague whose 

 valuable and harmonious co-operation can never be forgotten. 



Other friends have co-operated as referees or associate editors 

 in the preparation of the volumes, viz., Messrs. J. Gilbert Baker,
