 Eunice mutilata, n. sp. 



(Plate IX, Figs. 3G, 36a-rf— 40.) 



This species is represented in Mr. Goode's collection by an anterior 

 fragment composed of 39 segments, length 30'"°'; and by a posterior 

 fragment, 180 segments, length 90""". These may have belonged to 

 the same specimen, but do not make up the whole of any specimen, an 

 intermediate part, of unknown length, being lost. 



The head is distinctly and deeply bi-lobed. 



The antennie rather delicate, cylindrical, smooth, bluntly rounded at 

 apex; median antenna 3.5'"'" in length, reaching back to the middle of 

 the fifth (third setigerous) segment; inner pair, length 3'""'; outer pair 

 a mere trifle shorter than the inner. 



Eyes small, black, circular, between the bases of the paired antennae. 



Buccal segment equal in length to the three segments following it, 

 taken together; second segment a little shorter than tlie third. 



Tentacular cirri as long as the buccal segment, conical, apex blunt. 



The branchiae begin on the seventh setigerous segment; on the sev- 

 enth, eighth, and ninth segments, a single filament; on the tenth, elev- 

 enth, and twelfth, two fllaments; on the thirteenth, fourteenth, and 

 fifteenth, three filaments; from the sixteenth to the thirty-seventh, 

 four filaments (Fig. 36b) ; on the posterior fragment the branchiiXi have 

 but a single filament (Fig. 36c), becoming very delicate and short on 

 the posterior segments (Fig. 36d). 



The dorsal cirri, largest on the first setigerous segment (Fig. 36), 

 growing progressively smaller (Fig. 36&); at first finger-shaped, then 

 conical. On the first segment of the posterior fragment this cirrus 

 shows considerable increase in length, but is shorter than the branchia 

 (Fig. 36c*); while on the last segments (Fig. 36rZ), tliough the length of 

 the cirrus is about the same, it is much longer than the branchia. 



The ventral cirri are stout, conical, base swollen; outer third, on 

 anterior segments, cut off by a shallow constriction; longest on first 

 segments. 



Anal segment cylindrical, small. Anal cirri short. 



The ui^per (capillary) (Fig. 27) set* are very long and delicate; long- 

 est on the posterior third. The comb-like setae (Fig. 40) have their outer
