POLYCHvETA—BENHAM. 
71 
The existence of an independent flange below the pseudo-articulation of the 
hooded hooks in the anterior feet seems to be a characteristic feature of the species, 
and in some of the lower chmtse is a similar, but less developed flange on the convex 
side of the shaft. 
There is, however, one point in which my specimens differ from the account 
given by McIntosh. I do not find, in the posterior feet, hooded hooks like that figured 
by him on pi. XV IT a, fig. 18 ; they resemble, on the other hand, that which he 
attributes to L. japonica, and figures on pi. XVIII a, fig. 1. Has an error crept 
into the explanation of the plates ? 
The buccal segment agrees with that figured by Gravier (pi. Ill, fig. 35), as 
representing the adult condition of the species. 
The specimens in this collection number four ; one is imperfect and measures 
80 mm. by 3 mm. This came from a depth of 325 fathoms. Of the other three from 
the Macquarie Island, one is mature and filled with eggs, rendering the body yellowish 
in colour ; it consists of 133 segments, and measures 65 mm. by 2 mm. The remaining 
two are more slender, dark purplish-brown (in formalin), with a green iridescence. 
Localities .— 
Commonwealth Bay, Station 10, 325 fathoms (one). 
Macquarie Island, shore (three). 
Distribution .—Kerguelen (Kinberg, Grube, McIntosh) ; Magellan Strait (Kinberg, 
Elders), Kuegia, South Georgia, Falkland Islands, Bouvet Island, K. Wilhelm - 
II Land (Ehlers); lie Booth Wandel, Port Charcot, Peternrann, Admiralty 
Bay, South Shetlands (Gravier). 
Lumbriconereis macquariensis, sp. nov. 
(Plate 8, figs. 76-81.) 
This anterior fragment of a small Lumbriconereid consists of a head and 56 
segments, and measures 25 mm. by 1/25 mm. 
It is greyish in colour, non-iridescent. The specimen is not well preserved, 
and is rather soft. 
The prostomium is dark bluish grey, nearly hemispherical, with a median ventral 
furrow (fig. 76). The peristomium is interrupted by a buccal process of the second 
segment, and this process is grooved in the middle line ; furrows also exist, cutting 
into the edge of the lateral portions of the peristomium. Its appearance, in short, is 
like that figured by Gravier for the young of L. magalhaensis, and also like Elders’ figure 
for L . sphccrocephala. 
Were it not for further details, I should have referred it to the former species.
