description and figures. The marginal cilia of the elytra might be 

 more correctly described, however, as moderate in size and number 

 rather than long and numerous. Mcintosh pointed out that his 

 species i^ closely related to Polynoe (LcemUa) Imnellifera Marenzeller. 

 the only conspicuous difference being the absence of soft etytral 

 papillae. Polynoe subfumida Grube is another allied species.

 Harmothoe scriptoria sp. nov. PI. XXVIII, figs. 13-17. 



A pretty, dainty species with delicate, easily detached scales. 

 Moderately slender, slightly depressed, little tapered toward the two 

 ends which are nearly equally rounded. Measurements of t3^pe: 

 length 15 mm., width at X, body, 1.6 mm., between tips of parapodia 

 4 mm., between tips of setse 5.5 mm. Number of segments 39. Type 

 ? filled with ova. 



Prostomium (Pi. XXVIII, fig. 13) slightly longer than wide with a 

 distinct longitudinal dorsal median furrow for its entire length, slightly 

 and regularly convex laterally, broadly rounded or subtruncate 

 anteriorly, without distinct peaks and little or not at all overhanging 

 the bases of the lateral tentacles. Eyes, two pairs, black, small; 

 the posterior not more than one-fourteenth width of prostomium, 

 dorso-lateral, separated by two or three times its diameter from 

 posterior border of prostomium ; the anterior slightly larger, lateral 

 and slightly ventral, about one-third of length of prostomium from 

 its anterior end. Median ceratophore short and thick, projecting but 

 little from the cephalic sinus; style of median tentacle unknown but 

 its character may be judged Ijy the tantacular cirri. I>ateral tentacles 

 small, total length less than prostomium, arising from anterior face 

 of prostomium slightly below median ceratophore, their ceratophores 

 very short; styles regularly subulate. Palps two and one-half or 

 three times as long as prostomium, rather stout and projecting later- 

 ally beyond prostomium at base, tapering gradually to near tip and 

 then rapidly to a sharp point ; no distinct raised lines or ridges. Facial 

 ridge large, broad and rounded. 



Peristomial parapodia large and projecting well-foward beyond 

 prostomium, acha?tous, the tentacular cirrophores well separated; 

 style' moderately slender, i-egulaily tapered, without 'subterminal
