NEREIS ZONATA. 465 
tentacular cirri comparatively short, the longest being the dorsal of the posterior tentacular 
curi. Palpi “stout and squat.” Body small, 25 mm. in length, segments fifty-five, of a 
light green colour anteriorly, tending to bluish, occasionally with a bronzed lustre ; posteriorly 
yellowish-orange, due to the intestine, and in the females to the orange ova. Feet character- 
ised by the distinct separation of the dorsal and ventral divisions, the tip of each having 
two triangular lobes; the dorsal cirrus is long, and the ventral short. Dorsal bristles with 
elongated tips and homogomph, ventral superiorly homogomph and heterogomph, inferiorly 
heterogomph and falciform heterogomph.

Habitat.—A male heteronereid at Oddicombe in February (Elwes) ; piles of the wharf 
at Milbay Docks, Plymouth, fairly numerous (Ramsay). 
Abroad it was found originally at Naples by Claparéde. 
The description of this species has already been given under Leptonerers vaillanti in the 
volume published in 1910, p. 264, with a figure, and a coloured figure is now added (Plate 
CXVI, fig. 9). 
Nereis zonatTa, Malingren, 1867. Text-fig. 172. 
Specific Characters —Head resembling that of Nereis pelagica, but the eyes somewhat 
larger, and the tentacles and tentacular cirri longer and more slender. A band of dark 
pigment runs in the line of the eyes, and another of white passes forward between them. 
Maxillee with six to seven teeth; paragnathi generally finer than in N. pelagica; groups 
VII and VIII differ, the former presenting the two largest in the series, and the larger distal 
denticles are more isolated, whilst the proximal are more minute. Body typical. The lobes 
of the feet are more acute than in N. pelagica, and the coloration is distinctive, viz., dorsally 
banded with reddish brown.
