A botanist is of course always anxious to seize a rare plant, but the notifi- 
eation of such a capture, especially in the case of doubtful species, is very 
tantalizing to a traveller who may follow in his steps. I have, therefore, aimed 
at distinguishing plants that may be found again in the localities named, thus 
assisting the inquiring student, rather than at investing doubt in the robe of 
rarity, thus leaving room for future correction, and engendering perpetual dis¬ 
appointment. That further investigation of this district may probably bring to 
light “ fairer flowers ” than it has yet been my fortune to gather, no one is more 
aware than myself. Such at a future time I may record, and in the interim 
wish a successful campaign to all brother botanists. 
ON SCIENTIFIC NOMENCLATURE AND CLASSIFICATION, ILLUS¬ 
TRATED BY AN ARRANGEMENT OF THE BRITISH FALCONIDiE. 
By R. H. Sweeting, Suegeon, 
The practice of using Greek words for the generic, and Latin for the specific 
names of birds and other animals, did not originate with Mr. Any-one (see 
p. 150), but was the invariable plan—whenever admissible—of the illustrious 
Baron Cuvier. The following are specimens, taken from hk Regne Animal :— 
Per7iis apivorus^ Cargocatactes nucifraga^"^ Machetes pugnax. Classical names 
for birds, &c., whether Greek or Latin, or Latin and Greek, ought, if truly 
appropriate, to be considered equally admissible. Where both languages are 
employed to designate species, I am quite of the opinion that the Greek should 
take precedence of the Latin. 
I have been a very humble student of the delightful Book of Nature (particu¬ 
larly as regards the birds of the British Islands) for many years past. I will, 
however, only at present trouble you witli my notions on the names and most 
appropriate classification of one family, to which I have given my most parti- 
* Wq very much question whether our correspondent ever met with the name Caryocatactes 
nucifraga in any edition of the Regne Animal': as far as we are aware, the only author who uses 
it is Nilsson, in the OrnitJiologia Suecka.^'Eji.,
