Hab. Also among Filograna, from the Moray Firth. 
Several specimens were obtained. 
Remarks. This species somewhat resembles Pseudanthessius 
Thorellit (B. & R.), but differs particularly in the form of 
the anterior foot-jaws, in the proportional length of the inner 
branches of the fourth thoracic feet, and in the form of the 
abdomen. 
REMIGULUS *, gen. nov. (provisional name).

Body cyclopoid. Anterior antenne short, six-jointed. 
Posterior antennee three-jointed, without a secondary appen- 
dage. Mouth-organs rudimentary—the mandibles, maxille, 
and foot-jaws consist for the most part of simple stylet-shaped 
appendages. ‘The first four pairs of thoracic feet have all the 
outer branches three- and the inner two-jointed. Fifth pair 
unbranched, two-jointed. 
The genus Remigulus is provisionally instituted to include 
a curious cyclopoid copepod from Loch Linnhe, west of Scot- 
land. The following is a description of the species :— 
Remigulus tridens, sp. n. 
(Pl. XI. figs. 15-20; Pl. XII. figs. 1-3.) 
Basal joints of the six-jointed anterior antenne armed with 
three prominent teeth (PI. X11. fig.1); when theanimalis viewed 
from above the basal joints with their armature are entirely 
hidden by the boldly rounded forehead. The formula shows 
the proportional length of the joints of the anterior antennae— 
lO nda abe 
i ec hs Ven: 
Posterior antenne stout, the second and third joints subequal 
and shorter than the first ; the second joint is more or less 
covered with cilia and armed with a stout hooked spine at 
the distal end; the last joint, which is narrower than the 
preceding one, bears four spiniform and geniculate terminal 
sete. Mandibles and other mouth-organs as described in the 
generic definition (Pl. XI. figs.17,18,19; Pl. XII. fig.2). The 
first and second joints of the outer branches of the first pair of 
swimming-feet are furnished exteriorly with a marginal row 
of small teeth ; the joints of the short and stout inner branches 
are subequal and are each provided with a plumose seta on 
the interior edge, while the second joint is strongly dentate 
on the outer margin and armed at the apex with two small 
hook-like spines. The inner branches of the next three pairs
