The dorsal and ventral surfaces of the body are smooth save for 
the distinct segmental borders. The first segment with elytra forms 
a low collar behind the prostomium. Its ventral cirri are elongated, 
almost approaching the tentacular cirri in length. Median parapodia 
(fig. 16) have long dorsal cirri with numerous long papillae. Neuropodia

Ficure 1.—Eunoe uniseriata, new species: a, dorsal view of anterior end, without elytra; 
b, anterior view of seventh parapodium; c-e, notoseta, with detailed views of tip and 
middle section; f-h, upper neuroseta, with details of scales (g, optical section); 7, lower 
neuroseta; j-/, elytron, microtubercles, and macrotubercle. 
are longer than the notopodia and terminate in finger-like extensions 
above the aciculae. The ventral cirri are smooth. The presence of 
elytrophores on a tail end (paratype) indicates that the elytra cover 
most of the body. 
All setae have entire tips. Notosetae are stouter than neurosetae; 
they are yellowish and finely serrated almost to the pointed tip; the 
distal rows of spines are irregularly spaced (figs. 1c-e). There are two 
kinds of neurosetae. The upper neurosetae (figs. 1f-h) have two longi- 
tudinal rows of spinose scales. Similar but more delicate scales are
