66 EITMIDA SAXGUINEA. 



This interesting species is remarkable for the structure of its head and the foliaceous 

 condition of the dorsal cirri. In the position of the median tentacle it differs from all 

 other forms in the genus, and further investigation of the type is necessary. 



Besides the foregoing, several varieties of Eulalia occur from Gal way, deep water 

 off St. Andrews Bay, and elsewhere. In these the eyes vary considerably in size, some 

 being larger, others smaller than in the type, and the dorsal cirri are shorter or longer. 



Genus XXXII. — Eumida, Malmgren, 1865. 



Eumida, Claparede (1868) states, is distinguished by the presence of a small but 

 normal lamellar ventral cirrus below the last tentacular cirrus. He would, therefore, for 

 the moment make Eumida (Eracia, Be Quatref.) a sub-genus of Eulalia. Five tentacles, 

 median on the vertex; four pairs of tentacular cirri. First segment soldered to the 

 head-lobe (Levinsen), and first pair of tentacular cirri spring from it. The arrangement of 

 the dorsal and ventral longitudinal muscles and other features as in Phyllodoee and Eulalia.

Specific Characters. — Head rounded, cordate, broader than long, the large black or 

 brownish-black eyes thus being prominent. Anterior tentacles of moderate length, 

 subulate; median, somewhat shorter, arising in front of the eyes. Tentacular cirri of 

 moderate length, the dorsal in each pair being the longer, and all taper from the base to 

 the filiform tip, which in the posterior pair is finely attenuate ; the ventral of the second 

 pair is slightly flattened and approaches a narrow lanceolate form. Body one and a half 

 to three inches in length, of considerable proportional bulk, soft, and mobile ; somewhat 

 narrowed in front, and tapered posteriorly, where it ends in two fusiform or subulate 

 styles. Colour light greenish-brown, yellowish, straw-coloured, or almost translucent 

 anteriorly, with a faint straw-coloured line along the centre and a dusting of brownish 

 grains. The first segment has a white bar or white grains. In many a narrow white 

 or yellowish bar occurs at each segment-junction. In spirit it is generally madder 

 brown. Proboscis long, transversely rugose behind the tip, which has twenty papilla? 

 (Malmgren). In the typical foot (sixtieth) the dorsal cirri are sub -vertical, broadly 

 ovate, with an acuminate tip, while the base is sub-cordate. It is borne on a long 

 pedicle (ceratophore). Spinigerous process comparatively long and bifid. The translucent 

 shafts of the bristles have a distinct shoulder, a bevelled tip with spinigerous ridges, 

 and a minutely serrated terminal blade, longer than in the ordinary Eulalia, and tapering 

 to a fine tip. The ventral cirrus is broadly lanceolate, with a somewhat acuminate tip, 

 which does not quite reach that of the spinigerous lobe, and thus is shorter than in the 

 tenth foot.
