244 Messrs. T. and A. Scott on some 
refers to Claus’s specimen as a “ unique exemplaire.” We 
intend to describe and figure the Moray Firth specimen 
later on. 
AMPHIPODA. 
? Cyprotdia brevirostris, sp. n. (Pl. XIII. figs. 1-11.) 
Natural size 1°54 millim. (75 of aninch). Like Cyprotdia 
damnoniensis, Stebbing, in general appearance. Cephalon 
about equal to the combined length of the first two segments 
of the mesosome. Rostrum triangular, short, not reaching 
to the penultimate basal joint of the superior antenne; the 
rostrum, though small, is quite distinct. Second segment of 
the mesosome not more than half the length of the next. 
Eyes conspicuous, consisting of numerous lenses, the centre 
ones only appearing to be pigmented. Superior and inferior 
antenne similar to those of Cyproidia damnoniensis, but no 
trace of a secondary appendage could be observed on the 
superior antenne even with the aid of a Swift’s -inch objec- 
tive; the number of hairs on the first joint of the flagellum of 
the same antenne is also greater and they are arranged in six 
pairs ; each pair springs trom a small papilliform base (fig. 2). 
The mandible-palp, if applied to the mandible, extends con- 
siderably beyond it, and is therefore proportionally much 
longer than the mandible-palp of Cyproidia damnoniensis 
(fig. 4). The first and second gnathopods are similar to 
those of that species, but the fingers are not serrate on the 
lower concave edge (figs. 5 and 6). The third and fourth 
pairs of coxal plates are greatly developed (fig. 1). The 
fourth pair is about one and a half times as deep as the corre- 
sponding segment of the mesosome ; they also extend laterally 
beyond the sixth segment, and as their posterior excavation, 
which is comparatively narrow, is filled up by the fifth pair 
of coxal plates, the basal portions of the fourth and fifth 
pereiopods are almost entirely concealed. Third pair of 
pereiopods slender, basal joint of the last pereiopods lamelli- 
form, becoming wider towards the distal end, and produced 
downwards posteriorly to an acute angle (fig. 8). Uropoda 
and telson as in Oyproidia damnoniensis. 
Hab. Moray Firth ; washed from Filograna implexa from 
a depth of over 40 fathoms. 
Remarks. This species resembles Cyproidia damnoniensis, 
Stebbing, in several of its characters, but it is at once distin- 
guished by the great size of the third and fourth coxal plates, 
‘here are some other, but less obvious, points of difference, as, 
for example, the absence of a secondary appendage to the
