not pointed as in other EurytAoë-species but have an obtuse, oval tip, somewhat resembling 



if the dorsal foot in Amphinome rostrata (Chall. PI. II. \, figs. 11 and 12). The noto- 



lium is very short and its fascicle contains long, simple bristles of the same kind as those of 



the neuropodium; moreover there is a small number of harpoon-like setae, conspicuous by their 



white colour, about half as long as the preceding and with denticles of modera . Whereas 



the ventral cirrus represents only a short conical appendage, the dorsal cirrus extends to half 



the length of the bristle-fascicle. The branchiae commence on the third segment and consist 



of a strongly ramified bush of filaments. 



It is with some hesitancy that this species is ranged among the genus Eurytkoë, from 

 which it deviates not only by its general appearance, the long neuropodia, the simple elongated 

 hristles. the situation of the t list pair of branchiae l ) etc.; however because the neuropodial fascicle 

 sides the simple elongate bristles contains some shorter bifurcate ones, it may be supposed that 

 the I I cimen perhaps represents an epitocous form, for this worm was catched with the 



pelagic net. while numerous other Eurytkoë-specimens all were obtained on reefs. 



In the collections of the Leyden Museum 1 met with a smaller specimen, collected by 

 Mr. SchAdler on the West-coast of New Guinea, Skroe; it is also a female, full of eggs. Its 

 length mcasures 72 mm., whereas the number of segments amounts to about 120; each segment 

 has a brown spot in the ventral median line. Its caruncle is very small and only extends over 

 the first segment; the anal cirrus is a rectangular papilla with round corners and a black spot 

 in the middle. 



Genus nov. Benthoscolex J ). 



Body oblong oval, agreeing in general appearance with that of Chloeia. Caruncle short, 

 with three parallel, longitudinal ridges. Eyes absent. Branchiae commencing on the 6 th segment, 

 strongly developed on the posterior segments. Furcate bristles. An unpaired anal cirrus.
