Eulalia minuta n. sp. 



PI. IV, f. IO, 12, 14. 



Locality: 



The Ingolf-Expedition St. 29. 65°34' N. L. 54°3i' W. L. Davis Strait. 



Five entire specimens and some fragments have been captured at the above named locality. 

 It is a very small species; the largest specimen examined had a length of 5 mm. and a breadth of 

 1 mm. The body consists of a relatively small number of segments varying according to the dimen- 

 sions of the different specimens, 24—30 in the present individuals. 



The cephalic lobe is nearly semi-globular in shape, dorso-ventrally somewhat flattened. The 

 tentacles are long and slender, the unpaired somewhat longer than the four paired and a little more 

 slender than the latter. Eyes are present and situated near the base of the cephalic lobe (fig. 14, PI. IV). 

 The tentacular cirri are fusiform or lancet-shaped, while the tentacles are nearly filamentous in shape. 

 At their base they are strongly constricted and they are provided with a distinct basal joint. Towards 

 the distal half they taper quickly and form a thin terminal filament. The dorsal tentacular cirri are 

 somewhat longer than the ventral. Among the dorsal cirri the hindmost on each side is the longest; 

 among the ventral cirri the foremost is the longest. 



The dorsal lamellae are almost as broad as long; the shape of the latter is almost cordate or 

 ovo-cordate; the connective tissue forms a meshwork showing a dendritic ramified figure. The ventral 

 lamella is conspicuously narrower than the dorsal and overhangs the parapodium with its distal half 

 (fig. 10, PI. IV). 



The parapodium itself is only a little prominent. 



The setse present in a number of c. 12 in each parapodium are rather strong yet relatively 

 more slender than in the preceeding species. The dilatation in the tip of the shaft is only a little 

 prominent; it forms a step on the one side of the bristle and terminates in an outgrowth on the 

 other side; this outgrowth is finely denticulated. 



The endblade of the bristle is short; it tapers quickly from its proximal end, and the denticula- 

 tion along the edges is exceedingly delicate and difficult to see even under high magnifying power.
