and scarcely half the length of the outer branches ; the first joint is very 
minute, the second is elongate and setiform, and bears a single terminal 
hair; the outer branches are slender and elongate, and the marginal 
spines are also slender (fig. 25). In the fifth pair the basal joint is small, 
interiorly subquadrangular, but produced exteriorly to form the base of a 
moderately stout seta; an elongate plumose seta springs from the inner 
angle. Secondary joint uarrow suborate, the length being equal to fully 
three times the width at the broadest part ; it is furnished with six sete, 
—three on the outer margin, one on the inner margin, and two at the 
apex (fig. 26). Caudal stylets elongate and narrow, rather longer than 
the last abdominal segment, aud somewhat attenuated towards the distal 
end. ‘Two small sete spring from the outer edge of each stylet, and rather 
nearer the base than the apex. ‘Terminal set, two—one small and one 
elongate (fig. 27). 
Habitat.—Near Carradale, Kilbrennan Sound. 
Remarks.—The species now described somewhat resembles Cletodes 
propingua, Brady and Robertson ; but the structure and slender form of 
the swimming feet readily distinguish it from that form, and also from 
the next. No males were observed. 
Cletodes hirsutipes, sp. u. (Pl. I. figs. 11-18). ; 
Description of the Female.—Length about *6 mim. (;5th of an inch). 
Somewhat like Cletodes propinqua in general appearance (fig. 10). An 
tennules five-jointed, short ; the first three and the last joints sub-equal ; 
the fourth is very small ; the second, third, and fourth joints bear several 
strong spines (fig. 11). The antennz are provided with short one-jointed 
secondary branches, each with two sete (fig. 12). Mandibles rather 
feeble, armed with about four elongate slender teeth (fig. 13). Both 
branches of the first four pairs of swimming feet short and stout ; the 
outer branches, three, the inner two, jointed ; the inner branches of the 
first pair are equal to about three-fourths the length of the outer branches, 
and the end joint is scarcely twice the length of the first joint; both 
the inner and the outer branches are densely fringed with short 
hairs (fig. 15). The next three pairs have also both branches fringed 
with short sete; in the fourth pair the outer branches are 
about one and a half times longer than the inner, and the apical 
sete are very long and plumose (fig. 16). In the fifth pair the basal 
joint is produced interiorly, so as to form a narrow and sub-quadrangular 
lamina, the apex of which reaches beyond the middle of the secondary 
joint ; itis armed with three stout spiniform sete,—one being at the apex 
and two near the middle of the inner margin ; the secondary joint is 
narrow oblong, the length being equal to nearly three times the width ; 
the outer margin is densely fringed with hairs, and four spiniform setze 
spring from the broadly rounded apex (fig. 17). Caudal stylets, about as 
long as the last abdominal segment, foliaceus, and somewhat distorted ; 
the inner margin being broadly and obliquely rounded, while. there is a 
slight concavity near the middle of the outer edge (fig. 18). 
Habitat.—Kilbrennan Sound, near Carradale ; rather scarce. 
Remarks.—The structure of the mandibles and the stout and hirsute 
thoracic feet are characters sufficiently distinct to distinguish this from 
other British species ; the fringe of hairs on the margin of the secondary 
joints of the fifth pair is frequently so coated with mud as to have the 
appearance of a continuous brownish-coloured border. No males were 
observed
