great work was the Methodical Synopsis of Shells, in folio, 
published 1685—1692, which may be regarded as the foundation 
of modern conchology. It was illustrated by fine copper-plates 
by his two daughters, giving figures drawn to the life of all shells 
then known, as well as figures of their anatomy. 
Lister’s first published work is the one which most directly 
concerns us to-day. This is in Latin and was published in 1678 
by the Royal Society. The title in Latin is lengthy and the 
book is really composed of four distinct works. The first is of 
spiders, the second of land and freshwater shells, the third of 
marine shells, and the fourth of fossil shells, or, as more cautiously 
put, of stones fashioned in the image of shells. 
It is the second of these treatises that is not only the first 
book upon British Land and Freshwater Mollusca, but also the 
first record of some of those found in our own county of Lincoln. 
Three species are definitely localized for Lincolnshire and 
bave been found on the same spots by our modern investigators, 
and a fourth is also definitely stated to occur in the county 
without mention of a particular locality. 
Of Cyclostoma elegans, a fine and conspicuous operculated 
shell, Lister says, writing for once in English: “I have found 
them plentifully in a woody high cliff upon the river Wharf near 
Oglethorp[ Yorkshire]; also at Burwell Woods in Lincolnshire.” 
In this Lincolnshire station, the species was re-discovered 
in 1886 by Mr. H. Wallis Kew, in the part of the wood known 
as Grisel Bottom. A year or two afterwards I myself had the 
pleasure of finding it in company with Mr. Kew, and I have 
also collected it in the Yorkshire station, on the very ground 
_ hallowed by the tread of the great Lister. 
Another of Lister’s shells is one we now identify as Hyalinia 
_ fulva, a small species which Lister speaks of as a somewhat rare 
little creature (admodum rara bestiola), found in Burwell Woods, 
_ where, in 1887, it also was re-discovered by Mr. Kew. 
A third, now identified as Pupa cylindvacea, also a very small 
Species, was found by Lister abundantly in a place which he 
called ‘‘ Estrope,” a name not now to be found on our Lincoln- 
shire maps. The place whose name seems most nearly to
