Additions to the Lichen Flora of the West Riding of York- 
shire. A. Shackleton and T. Hebden, “ The Naturalist,” 1893, 
p. 165. — It is highly satisfactory to find that in Yorkshire we 
have two students so thoroughly interested in the study of lichens 
as the authors of the above-named article have proved themselves 
to be, one result of their researches being the addition of 118 
species to the Lichen Flora of the West Riding. Many notes and 
points of interest in connection with the discrimination of species 
must have cropped up in preparing the work, and one cannot but 
regret that some of these were not introduced, as such give a ring 
of life to an otherwise bald list, and more especially when we call 
to mind the extreme brevity of many Nylanderian diagnoses.
