name of the author of both the genus and the species, where they 
are different, thus, Cyprina Islandica, Lin., Lam., the name of 
the person who instituted the species being always kept in close 
proximity to the specific name, as being more important than the 
generic name, inasmuch asit is to be unchanged. ‘The only 
difficulty in the way is, that the means for ascertaining the au- 
thor of a generic term are not always at hand, and it could hardly 
be expected that memory would serve for both genus and species. 
Whoever cannot adopt the latter method, should not fail to apply 
the former, as recommended. 
Any one who has observed the indiscriminate coupling of ge- 
neric and specific names of incongruous genders, induced by the 
removal of species from one genus to another, will see the pro- 
priety of the precaution proposed in rule F. 
These remarks are all that need be offered at this time. The 
Report itself is fully illustrated throughout, and cannot but do 
good. Wecannot but hope that some method will be taken to 
give it to the American scientific public in an entire form. 
vothing could have been more timely, in furtherance of the 
movement so simultaneously made at all the principal foci of 
science, than the Nomenclator Zoologicus of Agassiz. Nor is 
it probable that any man living is better qualified than he, to 
undertake a work of the kind. 
His plan is as follows. He first gives an alphabetical list of 
every genus which has been instituted, whether adopted or not, 
in each of the classes of zoology; he gives its author, the work 
in which it originally appeared, and the date of publication of 
that work; then the derivation of the name; and finally, the 
family to which the genus belongs. ‘Then there is to be a gen- 
eral register combining all the classes, thus bringing side by side, 
the names which have a double use, and showing where priority 
belongs. ‘The different items are so printed, in various type, 
upon the same line, as to be easily distinguished. We sincerely 
wish he had added one other item, which would have tended 
greatly to banish from among scientific men, sounds repulsive to 
classic ears—we mean the accentuation. 
So far as genera are concerned then, no zoologist will hereafter 
be excusable for using, for any new genus, a word already in 
use; nor for being ignorant of all the genera which have been
