ANNELIDS FROM THE N.E. PACIFIC, 241 
This specimen is referred to in Mr. Potts’ notes as a ‘blue 
nereid, among kelp-roots.”” It is a female heteronereid, of rather 
small size, measuring about 35 mm, in length, with 54 pairs of 
parapodia (the body is not quite complete posteriorly). The 
transition in the form of the parapodia occurs at nos. 16-17. 
There is, I think, no doubt that this nereid is of the same 
species as that figured and described by Izuka (loc. cit.) under this 
name. But while it agrees exactly in other respects with Izuka’s 
description and figures, it exhibits a difference in the paragnaths 
of the basal division of the proboscis (V-VIII groups). These 
are so numerous as to form a complete band around the proboscis, 
consisting chiefly of small, pale brown, rounded (not sharply 
pointed) paragnaths, covering closely almost the whole surface. 
Group VI is represented by a well-marked little bunch of large 
pointed paragnaths, which, if alone, would be almost exactly in 
accordance with Izuka’s figure, but these are surrounded by the 
small paragnaths just described, which invade area V and also 
link the dorsal with the ventral areas. VII-VIII are affected 
in much the same way. 
Izuka’s figures do indicate that the paragnaths of the basal ring 
are more numerous than those of European JV. pelagica, but I 
suspect that the present example must be a more extreme one, if 
not even an abnormality. 
The proboscis was only partially everted, so that it would be 
difficult to figure it satisfactorily. 
The modified parapodia agree in form exactly with those of the 
male heteronereid figured by M‘Intosh (8, pl. lxxi. fig. 7) and 
with those of other specimens from the British Isles. 
NEREIS VIRENS Sars. 
Nereis virens Sars, Grube (8), p. 6, Taf. 1. figs. 2, 4, 5, 6. 
NV. brandti Malmgren (9), p. 183; Ehlers (2), p. 563. 
NV. dyamusi Izuka (5), p. 160, pl. xviii. figs. 1-12. 
This large species was found in numbers in muddy beaches at 
Departure Bay, Pleasant Beach (Seattle), Barkley Sound, and 
Friday. Harbour ( fide collector’s notes). 
Two large examples are in the collection (locality @). 
Nereis virens is well known on the west coast of North America, 
from California to Alaska, and was recorded from the Sea of 
Okhotsk by Grube in 1849. The Japanese representative has 
been named WV. dyamusi by Izuka (see below). 
Malmgren (9, p. 183) decided that the specimens from the Sea 
of Okhotsk represented a distinct species, which he named 
NV. brandti. Ehlers (loc. cit.) followed him, but noted that the 
two species were so nearly allied “dass wir nur die Variation 
einer Grundform haben, welche circumpolar im Nordmeere ver- 
breitet ist.” 
More recent workers, however, agree in considering the Pacific 
representative as identical with that of the Atlantic coasts 
[Johnson (6), p. 398; Moore (11), p. 344], and I follow these.
