290 MIGRATORY BIRDS OF BODICOTE, OXFORDSHIRE. 



although eminently winter birds, yet have occurred so very rarely, that 

 their place seems rather under the heading of accidental visitors ; so 

 that, properly speaking, in the present class we can only number twenty- 

 one species for certainty.

THE HEPATICLE OF WARWICKSHIRE. 



BY JAMES E. BAGNALL, HON. LIBRARIAN BIRMINGHAM NATURAL 

 HISTORY AND MICROSCOPICAL SOCIETY. 



The following list of the Hepaticse of Warwickshire is the result of 

 an examination of many districts in the county during the years 1879 

 and 1880, my attention during this period having been especially given 

 to these plants. But although I have given the subject my best attention, 

 I cannot but think that much remains still to be done ; the time given to 

 the study has been short, and the seasons have been unpropitious. 

 Better seasons and more extended knowledge of these plants may 

 probably lead to the finding of many plants hitherto sought in vain. 



My principal text book has been that able synopsis, " Hepaticse 

 Europae," by Du Mortier, and the classification adopted is that of the 

 above work. 



All the species here enumerated are represented in my herbarium 

 from one or more of the habitats cited. Purton, in " The Midland 

 Flora, 1817-21," gives but few localities for and records but a meagre list 

 of these plants ; these are duly quoted, in all other cases the localities 

 given are taken from my own note book. 



Unfortunately for English students, Dr. Carrington's valuable 

 " British Hepaticas " is still incomplete, so that the only text books 

 available for such students are Hooker's " British JuugermanniaB," a very 

 prizable but expensive work rarely to be met with ; the oth volume of 

 Smith's " British Flora," in which this family is very ably treated by 

 Sir W. Hooker ; and Cooke's " British Hepatic©." This last is a very 

 fair synopsis, very useful, and remarkably cheap. 



As the nomenclature of Du Mortier differs from that of our English 

 authors, I have in each such case given the synonyms of both Hooker, 

 Purton, and Cooke. 



In studying this family of plants I may state that I have had the 

 advantage of being able to compare my specimens with those contained 

 in the " Hepaticse Britannicaa Exsiccatas," fasc. I. and II., by Carrington 

 and Pearson, also with numerous specimens received from my valued 

 correspondents, H. Boswell, Esq., E. M. Holmes, Esq., and W. Curnow, 

 Esq., and as I have in each case been very careful in my examinations, I 

 think my list, though short, will be found correct.
