lower half of the inner margin of the middle joint. The third pair 
(fig. 28) are somewhat similar to the second, except that they are rather 
more slender, and that the second joint of the inner branches bears a 
small spine on the distal end of its outer margin in addition to the two 
long terminal sete. The fourth pair, on the other hand, scarcely differ 
from the third except that the outer branches are rather more elongated 
’ (fig. 29). 
The fifth pair resemble very closely the fifth pair of the female in Cletodes 
limicola, so much so that, with the exception of the basal joint being 
rather more produced, the general configuration and armature of this pair 
are in the two species almost identical (fig. 30). 
The male is very similar to the female. The antennules of the male 
have, as usual, a modified structure (fig 22), and the fifth pair of thoracic 
feet are very small (fig. 31). In the fifth pair of feet the basal joint is 
nearly rudimentary, ana the secondary joint, which is of a narrow cylin- 
drical form, is provided with only two apical sete, as shown by the 
drawing. 
Habitat.—Moray Firth ; moderately rare. 
Remarks.—The form just described has been known to me for a con- 
siderable time, but has been left over from year to year, as I was in doubt 
whether the differences observed were of any real value. As, however, I 
have not been able to find any described species to which this form could 
be assigned, I have described it here under a distinct name. 
This form belongs to a group of Cletodes which are all closely related to 
each other, and exhibit this relationship by the similarity in the structure 
of the antennules and of the first pair of thoracic feet, but especially in 
the structure and armature of the female fifth pair; and perhaps the most 
typical species of the group is the Cletodes limicola of G. 8. Brady. In 
this group the antennules are usually composed of five joints, the penulti- 
mate one being very small ; in the first pair of thoracic feet both branches 
are short, but the inner rather shorter than the outer; the second joint of 
the inner branches is also distinctly narrower and considerably longer than 
the first joint. In the fifth pair the basal joint is small, and only slightly 
produced interiorly—sometimes not at all—and provided with few, 
usually two or three, sete. The secondary joints, on the other hand, are 
elongated and narrow and usually furnished with five setee—two at the 
apex, one on the lower part of the inner margin, and two widely separated 
on the outer margin. The form just described, while agreeing in some of 
its structural details with several members of this group, differs in one 
point or another from them all, so far as they are at present known 
to me.

This curious little Harpactid occurred very sparingly in the same 
Musselburgh gathering with the Laophontodes just referred to, Its 
bathymetrical distribution appears to extend from the littoral zone down 
to moderately deep water. The furcal joints are short and pyriform, and 
seem to be characteristic of the species. One or two other species of 
Cletodes, including C. limicola, G.S. Brady,* and C. lata, T. Scott,? were 
also obtained in the same gathering.
