(195.) Names of groups higher than genera should 
always he derived from the pre-<miinent type of the group, 
or, if of a tribe or order, from the character which is 
most universal. — The facility which this modern law 
of nomenclature gives to research is very great. It 
first originated among our own naturalists, about twenty 
years ago, and has since been universally acted upon in 
Britain, both in artificial and natural systems. It is 
clear, however, that before we impose a name upon 
a group which has never been characterised, we should 
carefully analyse it j without which we shall run no small 
risk of not discovering the tyiiical character of the 
whole, and consequently apply a false name. Thus, if 
the rasorial order had been sufficiently inevstigated, 
it would have been discovered that tlic peacock was the 
pre-eminently typical bird, and, therefore, that the pri- 
mary family would be the Pavonidee. In like manner, 
Muscicapa being more typical than Todus, the family 
to which both belong should be called the Musvieapida:. 
These changes, so far as the names are concerned, are 
comparatively trivial ; but while the whole science is 
undergoing a revision and correction, it may be as well 
to make these and every other necessary change of no- 
menclature at the same time. 
(196.) The highest reward of a naturalist is to have 
a genus called after his name. — “ No monument, says 
the celebrated Willdenow, “ of marble or brass is so last- 
ing as this. It is the only way of perpetuating the 
memory of true botanists (or naturalists), or of those 
who have benefited the science.” Linneus, whose judg- 
ment was always sound and practical, confined the 
names of genera thus derived to botany alone, wherein, 
even in his days, such groups were so very numerous.
