P0LLIC1PES CORNUCOPIA. 303 



segments, the first cirrus had, in the shorter ramus, eight 

 segments, of which the lower four were thick and pro- 

 tuberant, with the spines doubly serrated. In this same 

 specimen, the anterior ramus of the second cirrus had 

 twelve segments, of which the live basal ones were highly 

 protuberant, and thickly clothed with non-serrated spines. 

 In the third cirrus the basal segments of the anterior 

 ramus are highly protuberant. The basal segments in 

 the posterior rami of both these cirri, are slightly pro- 

 tuberant, but otherwise resemble the segments in the 

 three posterior pair. 



The Caudal Appendages (PI. X, fig. 22), in full-grown 

 specimens, just exceed in length the lower segments of 

 the pedicels of the sixth cirrus ; they are nearly cylindrical, 

 bluntly pointed, with five oblique imperfect articulations ; 

 the lower or basal articulations cannot be traced all round, 

 being distinct only on the ventral surface. There is a 

 row of short spines round the upper edge of each segment, 

 with a little, short tuft on the point of the terminal 

 segment. In a rather young specimen, however, with 

 its capitulum one fifth of an inch long, each appendage 

 certainly consisted of a single segment, with spines only 

 on the summit. 



Penis purple, with excessively short and fine spines in 

 tufts, chiefly near the extremity. In a specimen with a 

 capitulum only one fifth of an inch long, the penis con- 

 sisted of a mere pointed papilla, not so long as the caudal 

 appendage, and therefore equalling in length only the 

 lower segment of the pedicel of the sixth cirrus. 



Ovigerous frcena. — I could see none, though there were 

 two large lamellae in the sack. The ova were flesh- 

 coloured, but they had been dried and then placed in 

 spirits. The ova were wonderfully numerous, oval, much 

 elongated, and ^th of an inch in length.
