Islands, although abounding in corals and plants. Lastly, They 
indicate, in concluding, both the fishes, which, wandering from 
their native haunts, follow ships, sheltering themselves under their 
keel ; and those which various navigators have fallen in with in 
thick shoals in a dead state, and destroyed by causes still little 
known. This memoir, the result of observations full of sagacity, 
will be most highly appreciated by those who have had an oppor- 
tunity of judging on the spot of the facts which they have de- 
scribed with accuracy. — Ann. des. Sc. Nat.

21. Original Habitats of the Rose. — In Trattinick’s Synodus 
Botanica, it is mentioned, that the species of the genus Rosa 
found in Europe, have reached us from the East Indies, China, 
and Japan. The middle part of the Russian empire, the dis- 
tricts around Caucasus and Persia, are full of roses, of which the 
more western are mere varieties, and which have propagated 
themselves as such. Roses are rare in Africa ; there they are 
met with only in the northern districts ; while Europe, on the 
contrary, from the Uralian Mountains to the coast of Portugal, 
abounds with them. The roses of America have reached that 
continent through the Polar lands, and appear to be sprung 
from the Rosa Alpina, and R. Majalis. There are no roses in 
Australasia, nor have any species been met with in South 
America ; indeed, they scarcely occur any where to the south 
of the Equator. 
22. Number of Species of the Genus Rosa. — Willdenow, in his 
Species Plantarum, published in 1800, enumerates 39 species of 
Rose; Persoon, in his' Enchiridium Botanicum, increased the 
number to 45; Trattinick, in his Synodus Botanica, published 
in 1824, enumerates 206 species ; and since the appearance of 
that work, late discoveries make the total number of known spe- 
cies 240. These are divided into 24 series, each of which bears 
the name of some botanist, who has distinguished himself by his 
knowledge of this beautiful genus. Thus we have as names, 
the following : — 1. Jacquinia; 2. Smithiana; 3. Candolleana; 
4. Willdenowiana ; 5. Woodsiana; 6. Sprengeliana ; 7. Lin- 
kiana ; 8. Andrewsiana ; 9. Purshiana ; 10. Lindleyana ; II. 
Aitoniana ; 12. Pallasiana, &c.
