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- 

 tennae are somewhat broad. The feet are broad, composed of two 

 lobes, and are destitute of branchial filaments. The bristles are 

 jointed, and the setse 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 

 sohtary, 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 (palecp). 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 li 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 



Alfred Newton, 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 ru/a, 

 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 : —
