museum at Oxford. To this University the plates themselves 
were also bequeathed, and there they were republished in 1770, 
under the direction of the Rev. William Huddesford, keeper of the 
-Ashmolcan museum, who 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 was acquainted with. This edition ditfers from the 
former principally in containing several plates on one page : the 
wdiole number is 1085 (2S more than are comprehended in the 
first edition), but there do not appear plates 89, 16*4, 195, 196'* 
222, 923, 96I, which were contained in the original. The num-

fossils and anatomical subjects. These, however, 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 growth, did not imagine to be the

of all these, for the most part so accurate, came from the fair 
hands of this celebrated naturalist's daughters, Susannah and Ann 
Lister, whose names deserve to descend to posterity with their 
fathers, and whose truly meritorious industry and ingenuity are 
patterns for their sex. • 
The researches of Lister were by no means confined to the 
mere coverings of Testacea. 80 far was he from contenting him- 
self with pointing out the beauty and variety of the shells, that he 
not only collected as much as was 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 
" Ever 'citations," each exhibiting dissections of Vermes, and con- 
taining ample descriptions, in Latin. The first " Eiercitatio Ana- 
tomica' relates chiefly to the Limaces. Of the second (to which
