boscis, which, when exserted, is $ths of an inch long, and is about 
3 lines in breadth ; the proboscis is 4 lines at its greatest diameter. 
The head is rather short and conical, and strongly ringed. The an- 
tennze are somewhat broad. The feet are broad, composed of two 
lobes, and are destitute of branchial filaments. The bristles are 
jointed, and the setze straight and sharp. The segments of the body 
are very numerous, composed of a double ring, the one on which the 
feet are set being the narrower of the two and raised; while the 
whole surface of the body, especially on the upper side, is densely, 
though not very strongly, corrugated throughout its whole length. 
The proboscis is densely scabrous, and covered with very short dark- 
coloured bristles. The body tapers to a narrow point posteriorly, 
and terminates in a loosely connected short lobe, armed at the extre- 
mity with a slightly curved, horny, sharp-pointed claw.

8. SABELLARIA SAXICAVA, Baird. 
This Worm lives in the rock. The tube in which it lodges is 
solitary, and is evidently hollowed out of the solid (though not very 
hard) rock by itself, and appears to be quite round. 
The thoracic portion of the body is round ; the abdominal flat- 
tened, with an impressed line running down through its whole length. 
The head is surmounted by an opercular disk composed of two rows 
of stout, dissimilar bristles (pale@). The inner row consists of about 
ten stout, cylindrical, sharp-pointed bristles of a dark horn-colour, 
gradually increasing in size from the dorsal margin towards the ven- 
tral. The outer row consists of about eighteen bristles, not so stout, 
flattened, and finely denticulated on both sides for about half the 
length. The postoccipital segment of the body is long, of a dark 
colour, somewhat wrinkled, and marked with three or four fleshy 
tubercles, on each side. ‘The thoracic feet are three pairs, and are 
broad, but short. As only one specimen was found, it was thought 
unadvisable to dissect the whole worm out ; in consequence of which 
the extremity has not been seen. I am unable to say whether it 
terminates in a caudal appendage or not. 
The length of the exposed portion of the worm is 11 inch, the 
breadth about 2 lines. Probably the part enclosed in the tube may 
be of about equal length.

On AN ILLUSTRATION OF THE MANNER IN WHICH BIRDS MAY 
OCCASIONALLY AID IN THE DISPERSION OF SEEDS. By 
Atrrep Newrov, M.A., F.Z.S. 
Last summer, my friend Mr. Henry Stevenson, the Secretary of the 
Norfolk and Norwich Museum, showed me the singular specimen 
which, by his liberality, I now exhibit. It will be seen that it is 
the leg and mutilated foot of a French Partridge (Caccabis rufa, 
G. R. Gray), a great part of which is imbedded in a mass of clay. 
At my request he has since furnished me with the following parti- 
culars respecting it :—
