branches consist of one and the outer of two joints, as shown in the figure 
(fig. 29, Pl. VII.). The inner portion of the basal joint of the fifth pair 
is not developed, but looks like a flattened border to the thoracic segment 
to which it is attached. It is furnished with three marginal sete ; the 
outer portion projects outwards in the form of an elongate narrow process 
carrying a slender apical seta. The secondary joint has an obovate form, 
and is provided with five setz of variable lengths round the distal end. 
(fig. 30, Pl. VII.). Caudal stylets short, with a considerable space 
between them. ‘The thoracic and abdominal segments are all fringed 
more or less with cilia. 
Habitat.—Off West Wemyss, Firth of Forth. Rare. 
Remarks.—This small and very curious species was discovered within 
the valves of a dead Cyprina shell, accidentally picked out from among 
some trawl refuse. It seems to combine the form of one of the depressed 
Dactylopus with the anatomical characters of Laophonte. It differs, how- 
ever, from the typical Zaophonte in the structure of the third pair of 
swimming-feet, which in this species have the inner branches one and 
the outer branches twojointed. It also carries two ovisacs, which is 
very unusual among the Laophonte. It nevertheless agrees in so many 
particulars with the characters of that genus, that I propose, for the 
present at least, to place it among the Laophonte. Laophonte simulans is, 
so far, one of the smallest of the Forth species belonging to this genus. 
Sub-genus Laophontodes, nov. sub-gen. 
Like Laophonte, Philippi, except that the posterior antennz have no 
secondary branch, and the fifth pair of thoracic feet are one-jointed. In 
the second, third, and fourth pairs of thoracic feet the second basal joints 
are elongate, and the outer branches are articulated to the apex, and the 
inner branches to the margin, and near the proximal end of the basal 
joint. The two branches are more widely apart than is usual in the genus 
Laophonte. 
Laophontodes typicus, sp. n. (Pl. VIII. figs. 2-8.) 
Description.—Female. Length, ‘4 mm. (,;nd of an inch). Body seen 
fromabove, narrow, elongate ; the breadth gradually decreasing towards the 
posterior end. All the segments more or less angular. The first cephalo- 
thoracic segment is nearly quadrangular in outline ; the middle part of the 
front margin is produced to form a broad sub-truncate rostrum. Anterior 
antenne short, five-jointed. All the joints are comparatively elongate, 
except the fourth, which is very small. The formula shows the proportional 
lengths of the joints :— 
Posterior antenne two-jointed, and of moderate size ; no secondary 
appendage (fig, 4). Posterior foot-jaws small, three-jointed ; the end joint 
very small. Terminal claw slender, slightly curved at the apex (fig. 5), 
First pair of thoracic feet like those of Laophonte. Second joint of the 
inner branches is scarcely equal to one-third the length of the first joint. 
Terminal claw slender, strongly hooked at the end. A small seta springs 
from the base of the claw. Outer tranches three-jointed ; the first and 
second joints sub-equal, the third shorter, the entire outer branch is 
equal to fully half the length of the first joint of the inner branch (fig. 6). 
Inner branches of the second, third, and fourth pairs short, two-jointed, and 
articulated to the second basal joint near its proximalend. The first joint 
of the inner branches is very small, the other is elongate. Outerbranches
