adjidem sensus referri possint, in id maxime incubui ne ipse primum 
decent Us posteros in errorem ducerem. Summam sane diligentiam ad- 
hibui, lit veras species distinguendo, nan multiplicando citra necessita- 
tcm singulis, minutissimis licet, fidissimis tamen observationibus, quce ad 
animalium mores vitamque spectarent, exornarem." Some additional 
species, with farther remarks on many before described, were 
figured in an " Appendix" Avhich went through two editions, the 
first being published in quarto at York in the year 1681, and the 
atter subjoined to his edition of Gcedart's Insects. This entomo- 
logical work was published in an octavo form, with twenty plates, 
two of which contain figures of shells. The original " Appendix" 
is now become very scarce. 
It was in the year 1685 that Lister commenced the publication 
of his great Testaceological work entitled " Historia sive Synopsis 
methodica Conchyliorum" which was divided into four books, be- 
sides a mantissa. 
Lib. 1. De Turbinibus terrestribus. 
2. De Turb. aqua dulcis et Bivalvibus aqua dulcis. 
3. De Bivalv. marinis, et Conchis anatiferis. 
4. De Patellis, Dentalibus, fyc. et de Buccinis marinis. 
The plates (which were 1057 in number) had very different di- 
mensions; in some instances containing a single figure, in others 
several figures, and not unfrequently more than one distinct spe- 
cies on the same plate. Concise descriptions are engraved on most 
of them, with references, wherever they could be given, to the 
places whence the specimens were brought. Our author seems 
to have been principally indebted to the museum of Mr. Cour- 
tein for the means of representing and describing those species 
with which he was not himself provided ; but that his own collec- 
tion was not deficient, either in number or perfection of speci- 
mens, is evident from what remains of it in the Ashmolean 
museum
