The € present egies includes a few entries omitted in earlier 
lists: all papers not dated belong to 1891. ‘The titles only are 
cited of papers published in ‘The Naturalist.’ Abstracts of papers 
tead before the Geological Society of London appear in the 
“Geological Magazine,’ ‘Nature,’ ‘Philosophical Magazine,’ and 
‘Annals and Magazine of Natural History’: these are not cited in 
our list when the paper has been published in full in the Quarterly 
Journal of the Society. Papers read before the British Association 
are frequently published verbatim in some provincial journal, or in 
the * Geological Magazine,’ before appearing (in the following year) 
in the official Report. When practicable, we cite these under the 
earlier date, and supply the reference to the Re eport.
