Hab. The sea-shore in wet gravelly places. 



Desc. This resembles a small earth-worm, 3 inches long, capable 

 of extending itself to about G, when the body becomes as slender as 

 a sewing thread. It is not marked with a tortuous central blood- 

 vessel ; and is of a diffused red or reddish-brown colour mixed with 

 the usual yellowish tint behind, and rendered dusky about the middle 

 from the interranea. The ventral surface is slightly flattened. The 

 head is narrow, and forms an elongated cone ; but otherwise the 

 anterior portion is always thickest ; the remainder of the body is 

 filiform, and becomes distinctly indented towards the posterior ex- 

 tremity. The head is partially retractile within the second segment. 

 The first ten segments are broader but shorter than the succeeding, 

 the 10th armed with several strong spines in two fascicles; the 

 spines straw-yellow, faintly lineate near the base, cylindrical, with a 

 slightly curved rather obtuse point (No. I. fig. 4). All the other seg- 

 ments are furnished with four fascicles of bristles directed strongly 

 backwards, two on each side ; and on the hinder segments they issue 

 from small papillse. The bristles are colourless, slender, flexible, 

 straight or curved, the shaft cylindrical, a little thickened near the 

 middle, whence it tapers to an acute point (fig. 5), They are most 

 numerous on the anterior segments, which have from twelve to 

 fifteen in each fascicle ; the middle segments eight or nine ; and the 

 hinder not more than four or five. Anal segment small, cordate or 

 somewhat lobed, with the vent between the lobes.
