rri long, with short and numerous segments, with the exception ol those of the lirst 

 |).iir which are rather short aiul braad. 



First cirrus placed far from the second; its pedicel is relatively Ion rami short, 



slighdy unequal, the longest has also the broadest segments; both rami have eight segments, 

 the ing very minute. rhe segments on both rami bear strong bristles placed in a row 



near the anterior extremit) of each ■"-ment Mie segments of the strongest ramus have further 

 a dense clothing of bristles i>n the side which is directed towards the more slender ramus. 

 Whereas the smal! terminal segment of the more slender ramus bears three str< nies, the 



same segment of the stronger ramus lias one slender spine only; further a number of extremely 

 small hairs are placed at iis extremity. In the ruw of bristles al the extremity of the sixth and 

 intnts of the stronger ramus two or three bristles are wanting; minute scales are 

 ■ ■ ut at the places left open. Beneath the 1ms.i1 articulation of the irrus a long filamentary 



appendage is situated. 



nd to sixth cirrus much resembling each other, their length and the number 

 of the segments slightly increasing from the second to the sixth; in the second each ramus has 

 i 3 a 14, in the sixth r6 a 17 segments. The pedicels and the lowermost segments of the rami 

 of the second and third cirri are much more densely clothed with hairs than the same parts 

 of the fourth — sixth cirri. As a rule each segment of each ramus bears a row of bristles near 

 ctremity, two very strong bristles on the dorsal face of each segment near the articulation 

 of the following segment and a group of bristles on the ventral face, also near the extremitv of 



ment. The ventral face of most segments shows a row of very short stiff hairs. giving 

 it the appearance of being serrated. 



The rami <>f the 5 th and 6 lh cirri are slightly unequal; the outer ramus has 17, the 

 inner only 15 segments. 



Caudal appendages long, reaching as far as the end of the fifth segment of the 

 rami of the sixth cirrus. composed of 14 very slender segments each with a number of very 

 delicate bristles or hairs on its summit. 



Penis indistinctly ringed or segmented, tapering towards the extremity; numerous delicate 

 hairs - I over its surface and a dense tuft of slightly stronger hairs at its extremity. 



One ol the specimens I investigated was furnished with eggs which were united in one 



mass. The eggs were extremely numerous and very small. Most of them contained Nauplii 



and many seemed to have come out before the animal was caught and put into the preserving 



tluid. The form of the eggs was long-oval, their length was 0,3, the greatest breadth o,i 5 mm. 



Larvae without eyes or without black pigment in the eyes. 



This species was taken at : 



Stat. 316. February 19, 1900. Lat. 7 [9.4 S., Long. 11649. 5 E. Depth 538 m. Bottom; fine, 

 dark brown sandy mud. 



The specimens were found attached to the spines of Porocidaris elegans, a sea-urchin 

 which was caught with the trawl. There are in all a dozen large and about as many smaller 

 1 'tien one or two large and a few smaller specimens form a group, being attached 

 iother to tin- same spine.
