Micippe tumida, Bruzelius, Skandinayiens Amphipoda Gammaridea (1859), 
p- 99, pl. 4. fig. 19; Bate, Cat. Amphip. British Museum, p. 374. 
Superior antenne with very short peduncle, not longer than 
the head, first two joints subequal, last joint not half the length 
of the preceding ; flagellum long and slender, first joint long, 
following joints wider than long; appendage five-joimted. Jn- 
ferior antenne much shorter than the superior, but the peduncle 
considerably longer. Gnathopods of similar structure; wrist 
short, triangular ; hand regularly ovate, palm undefined, finger 
slender, only very slightly curved, as long as the hand. Pe- 
reiopods with peculiarly long, perfectly simple, straight nails ; 
last pair long and slender, thigh narrow, furnished with a most 
remarkable appendage on the middle of the posterior margin 
(which is not expanded); this appendage consists of a very 
long styliform process, the distal portion of which is a plume 
formed of hairs springing from all sides of the axis. Pleon 
with two small teeth on the posterior dorsal margin of the 
fourth segment. Te/lson squamiform, divided almost to the 
base, and consisting of two long, narrow, diverging portions, 
furnished with three or four lateral and two terminal long 
slender spines. Uvropods: first pair rather longer than second, 
both margined with numerous very long slender spines; last 
pair having on the basal portion a tuft of long slender spines ; 
rami subequal, long, narrowly lanceolate, fringed with very 
long plumose sete. Length not quite half an inch. 
T'wo specimens, taken by Mr. Jeffreys and myself, in July 
1866, in the Sound of Skye. Mr. Bate, in his ‘ Catalogue of the 
Amphipodous Crustacea in the British Museum’ (p. 374), 
states that he had seen a specimen from Shetland ; but possibly 
there may have been some mistake in this, as the species is 
not included in the ‘ British Sessile-eyed Crustacea.’ 
The short peduncle of the upper antenne, the ovate enatho- 
pods, and, above all, the extraordinary styliform appendage of 
the thigh of the last pereiopods at once suffice to distinguish 
this species. What the use of the last-mentioned organ is 
T can form no idea; the nearest approach to it in structure 
that I know among the Crustacea is to be found in the abdo- 
minal sete of the Cladocera, 
Genus Eriopis, Bruzelius. 
Body elongated, slightly compressed ; coxee small. Superior 
antenne with a slender peduncle and a very minute secondary 
appendage. Inferior antenne subpediform. Mandibles two-
