or secondary joints ; these joints, which are of an ovate form and about 
one and a half times as long as broad, bear five setze round the lower 
outer margin and end, the middle one being rather longer than the others; 
the produced inner portion of the basal joints, which scarcely reach to the 
end of the outer secondary ones, have the sides slightly rounded and taper 
to the narrowly-rounded apex ; they are each furnished with five sete— 
three on the lower inner margin and two close together at the apex, as 
shown by the following drawing (fig. 7). 
The furcal joints are shorter than the last abdominal segment ; they 
each appear to be abruptly truncate, and their principal sete are elongated 
and slender (fig. 8). 
Habitat.—In a shore gathering collected at Musselburgh, Firth of 
Forth, in 1894 ; rather rare. 
Remarks.—The copepod described above has as great resemblance to 
Stenhelia as to Dactylopus in its general appearance and in some of its 
structural details, as, for example, in the structure of the first thoracic 
feet, but in the structure of the antennules, mandibles, and fifth thoracic feet 
its relationship appears to be closer to Dactylopus; it differs from 
described species in structure of the antennules, in the comparatively stout 
form of the first thoracic feet, and in the form and armature of the fifth 
pair. It appears to be a littoral species, as I have only observed it in 
inshore gatherings.

Description of the Female——Body moderately stout, length about 
‘75 mm. (about .!, of an inch). 
Rostrum prominent, slightly incurved (fig. 17). 
Antennules short, eight-jointed, the first four and last joints sub-equal 
in length, the other three short ; the first four joints are also considerably 
stouter than the last four (fig. 18) ; the formula shows approximately the 
proportional lengths of the joints :—

The secondary branches of the antennz are composed of three joints, 
but the middle one is small. 
The mandibles are stout and sub-cylindrical, and the biting part is some- 
what oblique and armed with about three strong and several small 
spiniform teeth; the basal joint of the palp is somewhat dilated, and 
carries two branches, the proximal one being considerably smaller than the 
other, as shown in the drawing (fig. 19). | 
The second maxillipeds have the penultimate joint moderately elongated 
and narrow, with a fringe of small setz on the inner aspect of its proximal 
half ; the end joint is scarcely broader than the base of the terminal claw, 
which is moderately long and slender, and incurved toward the extremity

In te first pair of thoracic feet, the outer branches, which are com- 
posed of three sub-equal joints, are rather longer than the first joint of the 
inner branches ; the first two joints are armed with moderately strong 
spines on the outer distal angles, while the end joint bears, at the apex, 
two slender spines and two sete ; the first joint of the outer branches is 
moderately stout, but scarcely twice as long as the combined lengths of 
the outer two, which are small, narrow, and sub-equal : the inner branches 
are armed with a stout terminal claw and two setz ; the first and second 
joints are also each provided with a seta near the distal end of the inner
