DISCOVERY REPORTS 



The upper ventral bristles are long, slender and spinous with curved bidentate tips ; 

 the lower ventral bristles are shorter and broader; they are almost smooth and have 

 bidentate tips. There is a caudal appendage. The present specimen measures 4 mm. by 

 I mm. without the feet for about 24 chaetigers.

Specific characters. Body rather elongate for a Harmothoe. Number of segments 

 between 35 and 41. An average specimen measures 25 mm. by 3 mm. without the feet. 

 The lateral tentacles are short, about as long as the head, one-third as long as the 

 median tentacle and tentacular cirri, and one-fourth as long as the palps. The anterior 

 pair of eyes is placed in the middle of the head at its lateral edges. The elytra leave the

posterior extremity uncovered. They are fringed (Fig. 7 a) and carry numerous small 

 bollard-shaped tubercles with thick cuticular caps (Fig. 7 b) and a few large egg-shaped 

 or urn-shaped vesicles (Fig. 7 c). These large vesicles tend to be situated at the hinder 

 margin of the scales especially in the posterior region of the body. In the front region 

 they are distributed more widely over the surface. The dorsal bristles are stout and 

 strongly pectinated except at the tip, which is smooth. Just above the neuropodial 

 aciculum the apex of the chaeta-sac is produced into a finger-shaped process. The 

 ventral bristles (Fig. 7 d) are rather slender, with numerous frills and a bidentate tip. 

 The second tooth lies well below the terminal tooth.
