Hab. Southern shores of England. 



Desc. Body vermiform, subcylindrical, narrowed posteriorly, of a 

 yellowish-brown colour, with a series of milk-white spots along the 

 middle of the back, one to every segment, and there are several less 

 defined spots along the sides and above the bases of the feet. (Post- 

 occipital segment about equal in longitudinal and transverse diameter, 

 narrower than the following segment, with three whitish spots on 

 the front line, which is even and entire.) Head of two prominent 

 oblong lobes in front of the first segment, and over the mouth. 

 Antennae five, distinctly annulate, setaceous, the central longest, the 

 lateral next in length, and the exterior shorter. Mouth ventral, 

 with a thick lip, plaited on the ventral side. Post-occipital segment 

 very short, apodous, smooth, with a setaceous tentaculum on each 

 side from the anterior suture. Segments short, very distinct and 

 numerous, faintly iridescent or non-iridescent on the dorsal, but 

 perlaceous on the ventral surface, which is furrowed with a mesial 

 groove. Feet prominent, the first four abranchial, all somewhat 

 lobulated, furnished with a superior and inferior cirrus extending 

 beyond the setigerous branch. The branchise begin on the seventh 

 segment ; they are semipectinate, with, at their full development, 

 about eleven filiform branches rather distantly placed ; the anterior 

 and posterior pairs have few branches. Bristles in four fascicles ; 

 those of the upper fascicle unequal, long and flexile, simple, smooth 

 and setaceous ; those of the second short, stout and compound, the 

 shaft thickened upwards, obliquely truncate ; the apical joint falcate, 

 concave on the inner side, and denticulate ; the fascicle inferior to 

 the second is small, and consists of bristles similar to the first ; and 

 the ventral fascicle is made up of bristles like those of the second. 

 Anal segment with two short styles. Length 4-7" ; as thick as a 

 quill. 



Obs. The antennae, although jointed, are not moniliform. The 

 bristles are in four small fascicles, the bristles of the superior and 

 third being alike, and very different from those of the second and 

 fourth. The former are simple, long, flexile, smooth and setaceous ; 

 the latter are compound, comparatively short, stout, the shaft thick- 

 ened upwards and obliquely truncated, where the apical short joint 

 is articulated : this is falcate, concave on the inner side, and some- 

 what denticulate.
