Char. Body linear-elongate, slender, composed of numerous short, 

 almost equal segments : head distinct, exposed, broader than long, 

 with three small antennae behind approximated at the base, shorter 

 than the head : eyes two, at the base of the exterior antennae : no 

 tentacula nor tentacular cirri : mouth armed as in Eunice : feet uni- 

 ramous, with two fascicles of bristles; the bristles of one slender 

 and setaceous, of the other stouter, compound, with a short beak- 

 like piece articulated at the apex : anal segment with four very short 

 styles. 



1 . L. Ninetta, head bilobed in front inferiorly ; dorsal cirri subu-

Hab. The littoral region. South of England. 



Desc. Worm lumbriciform, as thick as a small quill, scarcely 

 tapered at the extremities, which are nearly alike. Head small, 

 obtuse and emarginate in front, inferiorly bilobed. Antennae, from 

 the posterior margin, approximated, very short and papillary, the 

 mesial one a little longer than the others. Eyes two, at the external 

 base of the lateral antennae. Segments numerous, narrow, nearly 

 alike, separated by an impressed suture, smooth, almost cylindrical, 

 with short protuberant feet ; the first segment is twice as long as the 

 second, and both are apodous. Feet abranchial, tuberculate, gra- 

 dually attaining their full development ; the bristles colourless. 

 Bristles of superior fascicle long and setaceous, curved more or less 

 above the middle, whence they are brought to a very sharp point ; 

 bristles of inferior fascicle compound, comparatively stout, the shaft 

 cyhndrical, incrassated upwards and cut obliquely at the top, where 

 there is articulated a short beak-like piece concave on one side and 

 obsoletely denticulated, as is well represented in the figure we have 

 quoted. This terminal piece is easily detached, and is hence often 

 not to be observed. The spine of the upper fascicle is of the usual 

 character, chestnut-brown, with a colourless base ; but in the lower 

 fascicle the spine is colourless, difi^erent in form, and minutely biden- 

 tate at the top. Anal segment semioval, with very short styles. 

 Specimens in spirits are of a uniform yellowish-brown or even cream- 

 yellow.
