The Dactylethra Miilleri of Dr. Peters, from Mozambique, and of 
Mr. Cope, from the Gaboon, most probably belong to this genus: but 
the beards are described as being placed ‘below the eyes;’’ in this 
animal they are far in front of the lower part of the eye, and situated 
at the angle of the gape, as in many Stluri and other fishes with 
bearded mouths. 
Note on Lepas anatifera. 
16 Union Terrace, Aberdeen. 
Sept. 12, 1864. 
Dear Str,—I send you a photograph of rather a remarkable spe- 
cimen of the common Barnacle (Lepas anatifera of Linnzeus), which 
was picked up by the fishermen in the Bay of Aberdeen a few 
days ago, and which you might notice in the ‘Annals’ if you think 
it worthy. 
The log of wood is about 27 feet long, and 16 inches in diameter, 
three sides of which are covered with millions of these animals in 
high perfection. The Barnacles, as they lie about it, make a diameter 
of 2 feet 9 inches, and, floating in the water, they spread out toa 
width of 4 or 5 feet. The shell, in the greater number, is fully 
1; inch long, while the peduncle is, in many, 18 inches. 
I am not aware of the Barnacle having been seen before in this 
part of the country, though I believe it is occasionally found on the 
western coast. 
It is probable that the pine-log to which the animals are attached 
must have floated from a southern latitude; so that an interesting 
problem is offered to science by its appearance in our bay. 
I am, Sir, 
Your obedient Servant,

On the Anatomy of the Balanophoree, as regards the Characters 
which it furnishes for the Classification of those Plants. By M. 
A. CHATIN. 
The Balanophoreze, with the Cytineze and Rafflesiaceze constitute a 
singular class of parasitic plants, which has received the name of 
Rhizanthee ; their flowers, which are sometimes small and grouped 
together, sometimes very large and solitary, often appear to push 
forth, like Mushrooms, from a sort of subterranean byssus. 
Their seed, which has been the subject of valuable investigations 
on the part of Messrs. Weddell, J. D. Hooker, Griffith, and Hof- 
meister, has its embryo formed only by a homogeneous cellular mass, 
like the spores of Cryptogamic plants—a simplicity of organization
