and distal extremity furnished with hairs — those upon the 
latter position are very long, and split at the extremity 
into two branches ; the hand is long and narrow, having 
the margins parallel and the apex truncate ; the anterior 
half is furred with short hairs, a few long and large ones 
are also attached to the upper margin and apex; the finger 
is attached near the centre, so that the palm consists of 
but half the apical margin ; its outline is waved, and the 
short finger is tuberculated upon the inner margin. The 
first two pairs of walking legs are uniform and tolerably 
robust ; the last three are equally so, but they have the 
second joint developed into an oval scale, which extends 
downwards as far as the extremity of the joint next suc- 
ceeding. The caudal appendages have their branches 
subequal, the penultimate pair are shorter than the pre- 
ceding or ultimate. The terminal branches are furnished 
with short spines upon the upper and inner margins, 
those of the penultimate have the extremity of the inner 
branch subapically furnished with a long spine, which 
gives this branch the appearance of terminating in a 
double extremity. The central tail-piece is divided to 
about two-thirds of its length; the outer and upper 
margin of each division is supplied with three equi- 
distant spinules, two or three more of which cover the 
apex of each half. These spinules or small hairs are 
subapically furnished with a branch still more minute. 
We have received specimens of this species from the 
Moray Frith, collected by the Rev. Mr. Gordon, of 
Elgin, and Mr. Edward, of Banff. From them our 
figure and description are taken. On a comparison with 
the figure given by Kroyer, our specimens appear to be 
comparatively longer, but in all other respects their 
identity appears to be complete.
