illustrated by nine good plates, and containing ample descrip- 
tions, with synonyms at length, of every known species of shell. 
The " Einleitung in die ConchyUenkenntniss nach Linne" sets out 
with an explanation of the Linnean system of Tcstaceology, to 
which it forms an excellent introduction. The systematical part, 
however, inverts the order followed by Linnaeus in his Sy sterna 
Nature?, as it begins with the Univalves and ends with the Mul- 
tivalves. Consistently with chronological detail, Ave ought to 
have mentioned in an earlier part of our notices of Schroter his 
republication of the plates of Gottwald's museum; yet this vo- 
lume not being wholly original, though so acceptable a present to 
the lovers of Tcstaceology, might, without impropriety, 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 which 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 1782. 
The museum itself was purchased by Peter the Great for 1000 
rubles. We have before spoken of the correctness and elegance 
of the engravings, which cannot fail to immortalise the name of 
Gottwald ; and his editor has imparted much additional value to 
the work by the subjoined letter-press,

Jin," has followed pretty nearly the steps of his countryman Smith, 
referring to no scientific author on the subject of Testacea, ex-
