At the above-named Station three sniall ZrtiVwöw/r^j-specimens were dredged, that are 

 characterised by a green ish hu e of the ventral side as well as of the palps ; the median 

 ventral region is transUicent. The dorsum is coated by a feit, that is covered with mud. There 

 are 14 or 15 pairs of transhicent elytra, leaving the median dorsal Hne bare. The stout dorsai 

 spines are golden-yellow, rather long, those of the anterior segments reaching to the anal 

 extremity, those of the median body-region extending somewhat beyond it (PI. XIV, fig. i). 

 Their shaft is provided along one side with two or three series of widely dispersed, pointed 

 tubercles ; there are 3 pairs of fangs, alternating, not very elongated. The ventral bri.stles (PI. 

 XIV, fig. 2) are slender, with a beard of thin pinnae, that are not very numerous ; the spine 

 beneath them is rather short, not separated by an interval. The ventral cirrus is short, not 

 tapering distally. The head is circular, as long as broad, with a pair of eye-peduncles, that 

 are rather large, cylindrical, but without pigment. The palps are very long, extending to the 

 14"' segment. 



The species measures about 15 mm. in length, whereas the number of its segments 

 amounts to 30.

 2 specimens. 



Two indifferently preserved specimens, that hardly can be identified with any of the 

 preceding species, are characterised by the presence of rather long golden-brown coloured 

 dorsal bristles ; those of the median body-region extend beyond the anal extremity (PI. XIV, 

 hg. 3). Beneath their barbed tip, that is provided with 3 pairs of alternating, elongated fangs, 

 the bristles are somewhat constricted, and their shaft, like those of Laetin. batheia^ show several 

 series of blunt conical tubercles, that are dispersed over the whole .surface. The ventral bristles 

 are provided with a beard of slender pinnae, without a spine beneath them (PI. XIV, 

 fig. 4). The ventral cirri are short, club-shaped, enlarged distally. A dor.sal feit occurs, hiding 

 the 15 pairs of elytra, that slightly overlap each other and cover the whole dorsum. The palps 

 are very long, e.xtending nearly to the middle of the body. Length of the body 23 mm.; the 

 number of segments about 33.

Two specimens from the above-named Stations must be identified with this species, that 

 is characterised by its short papilliform tentacle, its globular ocular peduncles without a tracé 

 of pigment and the hairy distal region of its ventral bristles. The smaller specimen has a 

 length of about 26 mm. and a breadth of 15 mm. (without bristles); the other one is larger.
