EULALIA (?) IMBRICATA. 



65 



Body flattened, tapered for a short distance anteriorly, and terminating posteriorly 

 in two elongate-ovoid caudal cirri. Foot with a large and broadly ovate dorsal cirrus 

 (lamella), an elongate-ovoid ventral cirrus, and a bilabiate setigerous region with bristles 

 having the ends of the shafts dilated and furnished with two long spines, whilst the 

 tapering terminal pieces are serrated (Ehlers).

Fig. 42. — Head of Eulalia imbricata (after Ehlers). 



Eulalia (?) imbricata, Ehlers, 1875. 



Habitat. — Dredged in the 'Porcupine' Expedition of 1869 in 664 fathoms, on 

 July 2nd, at Station 23, 56° 9' K, 14° 10' W. 



Head (fig. 42, after Ehlers) somewhat large, pentagonal, with the greatest breadth 

 posteriorly. The four anterior tentacles arise further from the tip than usual, whilst the 

 small median tentacle springs from the extreme central process of the head posteriorly. 

 No eyes. The head thus differs from the general type of the genus. 



Body about 13 mm. in length, 2 mm. broad, and has seventy segments. It is 

 flattened, tapered anteriorly, and yellowish- white in spirit. The first three segments 

 bear four pairs of tentacular cirri, the longest reaching from the third to the tenth 

 segment. The last segment has two elongate-ovoid anal cirri. 



The average foot has a broadly ovoid dorsal lamella (cirrus). The setigerous 

 process is two-lipped, the lower being larger than the upper. The distal end of the shaft 

 of the bristles is enlarged and two-spined, whilst the edge of the terminal sabre is 

 serrated. The ventral lamella (cirrus) is elongate-ovoid, and extends about the length 

 of the setigerous lobe.
