refers to Claus's specimen as a " unique exeraplaire." We 

 intend to describe and figure the Moray Firth specimen 

 later on. 



Amphipoda. 

 ? Cyproidia brevirostris, sp. n. (PI. XIII. figs. 1-11.) 



Natural size 1*54 millim. (p^ of an inch). Like Ci/proidia 

 damnom'ensi's, 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 antennse ; 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 

 antennae similar to those of Ci/proidia damnoniensis, but no 

 trace of a secondary appendage could be observed on the 

 superior antennae 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 antennae is also greater and they are arranged in six 

 pairs ; each pair springs from a small j)apilliforni 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 fi). 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 Cyproidia damnoniensis.

Uemarks. 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. 

 There are some other, but less obvious, points of difference, as, 

 for example, the absence of a secondary appendage to the
