HARMOTHOE AREOLATA. 349 



11. Harmothoe areolata, Grube, 1860. 



Sjoecific Characters.— Body elongate, slightly tapered anteriorly, more so posteriorly, 

 and terminating in two caudal cirri. Bristled segments 37 to 39. Head somewhat 

 ovoid, with two elongated peaks in front, and clearly separated by an interval from the 

 base of the median tentacle. Posterior pair of eyes on the dorsum and in front of the 

 nuchal fold, while the anterior pair under the peaks are almost invisible from the 

 dorsum. The median tentacle is of moderate length, gently tapered, little if at all 

 dilated below the filiform tip, and densely ciliated. The lateral tentacles are short, and 

 similar in structure. The tentacular cirri agree with the tentacle. Palpi of moderate 

 length, gently tapered from base to near the apex, which is short and filiform. They 

 have rows of short clavate papilla?, which diminish in size from base to tip, which is 

 bare. Scales fifteen pairs, imbricate, covering the dorsum and extending over the 

 bristles. They vary in shape from the rounded first pair to the reniform kinds, and the 

 D-shaped posterior pair are studded with horny papilla? of various sizes, from the small 

 rounded processes to the elongate forms which rise into bluntly conical spines pos- 

 teriorly. Margin ciliated posteriorly from the inner to the outer border. Those on 

 the outer border are densely grouped and long. Dorsal cirri of moderate length, 

 tapered and densely ciliated almost to the tip. In many the distal half of the process is 

 dilated, so that the organ is broadly spathulate, with the filiform tip projecting at the 

 distal region. Feet have a dorsal tuft of curved bristles which are densely spinous, 

 with a smooth tip, which has a streak as if a rudimentary tooth were present. The 

 ventral bristles are rather slender, with tapering bifid tips and well-marked spinous 

 rows. The ventral cirrus reaches beyond the base of the bristles, and has somewhat 

 short clavate papillae.

 Chsetopterus, and by the author frequently under stones at Herm.
