that there should be only one authority for new species^ and 
therefore each of them has attached his name to a moiety of 
the work, Dr. Gunther taking that portion in the study of 
which he was more particularly engaged at the time. Science 
is indebted for this work to the Government of Bombay, who 
most liberally assisted its publication by taking 100 copies. 
Most of the plates are drawn by Mr. Ford, and some of them 
surpass all similar productions in beauty of execution.

We have copied the full title of this work as indicating at 
once its contents. There is no originality about the introduc- 
tory chapters on the general history of bshes (pp. 124). The 
special part, the history of Fi’ench fishes, has many serious de- 
fects, of which the principal (Consists in the excessive multipli- 
cation of species; the author distinguishes not less than 91 
freshwater fishes, which maybe more properly referred to about 
54. The supposed new species taking scarcely the rank of per- 
manent or local varieties, the descriptions of their characteristics 
arc extremely vague. Although the author cpiotes some of the 
principal synonyms, he cannot have read or studied the works 
. to which he refers, otherwise it would not have been possible, 
after SiebokPs exact researches, to describe Abramis bugc/enhagii, 
A. abramo-TutiliiSy Alburnus dolabratus, &c., as distinct specific 
forms, without even mentioning that -they are now commonly 
regarded as hybrids ! The woodcuts by wliich the book is illus- 
trated are veVy unequally executed; thus, for instance, the 
head of the Perch on p. 134 is good, Avhilst that of Cyprinus 
collar'll on p. 332 is evidently made by some one who had a 
very crude idea of the construction of a fishes head. The new 
names occurring in this book will be subsequently mentioned 
without further comment.
