three years afterwards pvit into a Latin form, under the title of 

 " Recreafio Mentis etOcidi in ObservationeAiiiniaUum Tedaceorum." 

 It contains upwards of five hundred figures, not remarkable, how- 

 ever, for their accuracy ; the apertures of the Univalves are, in 

 many instances, represented as turning to the left instead of the 

 right. The descriptive part is loose and desviltory, and exhibits 

 few marks of scientific distribution, except the general division of 

 the subject into 



1. Univalvia non turhinata, 



2. Bivalvia, and 



3. Tiirhinata. 



In the inferior divisions this author has strangely separated spe- 

 cies naturally allied to each other. For instance, the Serpuhe, Den- 

 talia, &c. are left out of his fust class, and, as Avell as the For- 

 celluncce, distributed under the third ; and, with equal want of 

 consistency, he places the HaUotis and Nautilus (genera manifestly 

 turbinated) among those which he terms Univalvia non turhinata. 

 But it should be remarked, as a circumstance highly creditable 

 to Buonanni, that, in many instances, he has given the loci na- 

 tales of his species, which were too little attended to by testace- 

 ologists of that age. He has also treated of the formation of shells 

 in a manner more philosophical than could have been expected 

 at such a period. The subjects for his engravings were obtained 

 principal]}' from the famous museum of Kircher, which was 

 aftei'wards separately described by our author under the title of 

 " Museum Kircherianum." This volume contains forty-six plates 

 and five hundred and eighty-six figures of shells (besides those 

 illustrative of other parts of the collection), and the descriptive 

 and physiological matter of Buonanni's original work.
