illustrated by nine good plates, and containing ample descrip- 

 tions, Avith synonyms at length, of every known species of shell. 

 The " Eiiileituns; in die Conchi/Iicnkeniifniss nach Linne" sets out 

 with an explanation of the Linnean system of Testaceology, to 

 which it forms an excellent introduction. The systematical part, 

 however, inverts the order followed by Linna?us in his Sijstema 

 Natfoue, as it begins with the Univalves and ends Avith the Mul- 



tivalves. Consistently with chronological detail, we ought to 



have mentioned in an earlier part of our notices of Schroter his 

 republication of the plates of Gottwald's museum; j'ct this vo- 

 lume not being wholly original, though so acceptable a present to 

 the lovers of Testaceology, nught, without impropriet}^ perhaps, 

 have been excluded from the regular enumeration of works more 

 creditable to the author's reputation. Of forty-nine plates, forty- 

 three relate entirely to shells which had been in a great degree de- 

 scribed (though not in print) by the older Gottwald. The draw- 

 ings also from Avhich the figures were taken had been made by 

 that collector. At the death of Dr. J. C. Gottwald the plates and 

 MSS. fell into the hands of a bookseller, who (after they had un- 

 dergone revision and received additions from the author of whom 

 we have been treating) published them at Nuremberg in 17B2. 

 The museum itself was purchased by Peter the Great for 1000 

 rubles. We have before s[)oken of the correctness and elegance 

 of the ensravinos mIucIi cannot fail to immortalise the name of 

 Gottwald; and his editor has imparted much additional value to 

 the work by the subjoined letter-press.
