 were also bequeathed, and there they Avere republished in 1770, 

 under the direction of the Rev. William Huddesford, keeper of the 

 Ashmolean museum, Avho subjoined two indices, one connected 

 with Lister's own distribution, and the other with the Linnean, to 

 which last were affixed as many of the current English names as 

 the editor Avas acquainted Avith. This edition differs from the 

 former principally in containing several plates on one page : the 

 Avhole number is 1085 (28 more than are comprehended in the 

 first edition), but there do not appear plates 89, l64, 195, 196, 

 222, 923, 961, Avhich Avere contained in the original. The num- 

 ber of figures amounts to no fcAver than 1 153, exclusive of the 

 fossils and anatomical subjects. These, hoAvever, are not to be 

 considered as so many distinct species, since there is, doubtless, 

 a repetition of several, which the author, on account of difference 

 of colour and stages of groAvth, did not imagine to be the 

 same. We ought not to omit mentionins that the delineations 

 of all these, for the most part so accurate, came from the fair 

 hands of this celebrated naturalist's daughters, Sicsaiw ah and Ann 

 Lister, Avhose names deserve to descend to posterity Avith their 

 father's, and Avhose truly meritorious industry and ingenuity are 

 patterns for their sex. 



The researches of Lister Avere by no means confined to the 

 mere coverings of Testacea. So far Avas he from contenting him- 

 self Avith pointing out the beauty and variety of the shells, that he 

 not only collected as much as Avas in his power relative to the 

 habits of the animals, but also devoted great pains to the illus- 

 tration of their anatomical structure. He published three separate 

 " Exercitations," each exhibiting dissections of Vermes, and con- 

 taining ample descriptions, in Latin. The first " Eaercitatio Ana- 

 tomicu" relates chiefly to the Limaces. Of the second (to Avhieh
