differ in their form, and in the qnincuncial position of the fruits, whilst 
in our plant the verticillate arrangement prevails. Casnarina prisca, 
from an unknown formation of New Holland, described and figured by 
Miquel, exhibits younger female and male flowers, and does not offer 
any points of correspondence to our plant, nor does Casuarina Ileidin- 
geri, Ettingsh., from the older Tertiary beds of Dalmatia. 
Our species thus belongs to forms which remind us of older extinct 
ones, especially to Calamarite, inclusive of the Asterophyllites and 
Sphenoplnjlla of the Coal formation, and perhaps even Mlhophyllnm 
Bpecmum of the Bunter Sandstein. From my present stand-point, I 
hold that the creative power displayed itself in such forms even beyond 
the Trias up to the first or lower division of the Jura formation, — a 
result which is sufficiently notable to claim for our plant a certain im- 
portance amongst fossils, though we may be somewhat ignorant of its 
exact origin. I place it unhesitatingly in the Order Calamaria, near 
Annular la and Sphenophyllum.

OFFICIAL REPORT ON THE BOTANICAL DEPARTMENT 
OF THE BRITISH MUSEUM. 
By J. J. Bennett, Esq., F.R.S., etc. 
The principal business of the Department, during the past year, has 
consisted in the re-arrangement, with very large additions, of the 
genera] collection of Alga, of the extensive Order of luiphorbiacea, of 
le fycopodiacea?, Nymphaacese, and of a portion of the Composite. 
Itl the naming, arranging, and laying into the general Herbarium of 
*« remainder of Mr. Charles Wright's extensive collections made in
