182 Dr. Maton's and Mr. Rackett's 
rable in this part of the Systema, with which he seems to have 
been less conversant than with any other; and so little dependence 
is there on his references and synonyms, that the same figure is 
frequently found to be quoted for species most widely different 
from one another ; and even the same species, in more than one 
instance, is described twice. A writer who should undertake to 
rectify these errors would perform a truly valuable service to Tes- 
taceology. Such an opportunity presented itself to a country- 
man of ours, who has recently put the Syst . Nat. into an English 
dress, and who has professed having availed himself of the im- 
provements and additions of later naturalists; yet we cannot find 
that Dr. TURTON has done more than having trodden in the 
steps of Gmelin, not perceiving even the most glaring of his 
inadvertencies. It would be wholly useless and superfluous, 
therefore, to assign any place to the English editor of Linnaeus's 
Systema but that of a mere translator. . . 
The remark we have made relative to the comparatively small 
number of rare species figured by Seba is applicable also to the 
superb and costly work of 
REGENFUS, 
which, though it reflects honour on the artist and on the monarch 
by whom he was patronized, has conferred but little benefit on 
Testaceology as a science. It contains twelve beautifully coloured 
plates, in imperial folio, each plate compehending twelve shells. 
The descriptive part (which is in both French and Danish, and 
was the work of Professor Kratzenstein and Dr. Ascanius,) is pre- 
ceded by a full list of authors, and by an account of the prin- 
cipal cabinets of shells at that time existing in Denmark. Front- 
ing each plate is a good table of synonyms, which may be consi- 
dered as one of the most useful parts of the work ; but the spe-
