the British Pista cristata, O. F. Muller, and of the latter JEupista Darwini, McIntosh,
dredged by the “ Challenger ” in the Pacific. The forthcoming treatise on the annelids
of the “ Siboga ” expedition by this accomplished author will be full of interest.
Hessle (1917) arranged the Terebellidae so that this genus followed Trichobranchus
and Terebellides, on the ground that it, too,' had anterior hooks with long shafts, but in
other groups, such as the Polycirridea and Maldanidse (e. g. Rhodine), there is a tendency
to a similar condition, so that it appears to be unnecessary at present to break up the old
arrangement.
1. P ista c r is tata , 0. F. Muller, 1776. Plate CXIX, figs. 9 and 9 a—body and valvular
end of tube; Plate CXXVa, figs. 8—8 c"—bristles and hooks.
Specific Characters.—Cephalic plate with a thick dorsal collar without eyes (in
preparations). Anterior fold often symmetrically sinuous. Tentacles of moderate length
and grooved. Body 120—150 mm. long, rounded dorsally, with.twelve (Marenzeller gives
seventeen, about twenty, Hessle) ventral shields anteriorly with reddish margins, and a
deep groove throughout the rest of its extent, moderately enlarged anteriorly, and
tapering posteriorly to a slender tail with a valvular anus at the tip. Papillae in segments
6 and 7 behind the setigerous process. Segments 2, 8 and 4 with lateral lappets. Body
of a uniform reddish orange, with a deep orange bar at each scute inferiorly. Lips reddish
and the tentacles pale orange. A deep red patch occurs at the anterior part of the second
region. The continental examples are greyish-red or brownTsh-red anteriorly, yellowish-
grey posteriorly. Two branchiae with long stems, much and dichotomously divided
filaments, forming a dense and whorled bush. They arise from the anterior border
of the fourth segment. Seventeen pairs of setigerous processes, which in front
converge towards the dorsal median line. Hook-rows double from the. eleventh to
the twentieth segment (Marenzeller), and the tori are cinnamon-coloured. Hooks with
a main fang and three or four teeth above it in lateral view, and with long shafts as in
the Lanicides.
