ad fidem sensus referri possint, in id maximc incubui nc ipse primum 

 dcccpfns posteros in errorem dnccrem. Summam sane diligentiam ad- 

 hibui, ut vera* species distingiicndn, non multiplicando eitra necessita- 

 te™ singulis, minutissimis licet, Jidissimis tamen observationibus, qua; ad 

 animalium mores vitamque speetarent, exornarem." Some additional 

 species, with further remarks on many before described, were 

 figured in an " Appendix," which went through two editions, the 

 first being published in quarto at York in the year 1G81, 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 ct Bivalvibus aqua dulcis. 

 5. De Bivalv. marinis, et Conchis anatiferis. 

 4. De Patellis, Dentalibus, #c. et de Buccinis marinis. 

 The plates (which weFe 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 Avhence 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 Avhat remains of it in the Ashmolean 



museum
