of legs ; the third joint is short ; the fourth reaches as far 
the thigh is oval, the metacarpus posteriorly dilated and 
distally produced behind ; the wrist and hand subequal, 
straight, and the finger short and straight. The sixth 
pair closely resemble the fifth, except that the coxa is 
shorter, and the thigh is fringed with plumose hairs. 
The seventh pair of legs are more than twice the length 
of the preceding pair : the coxa is short, the thigh di- 
lated, the metacarpus long and narrow, longer than the 
thigh; the wrist is as long as the metacarpal joint ; the 
hand is a little shorter and more narrow than the w r rist, 
and internally fringed with cilia ; the finger is nearly as 
long as the hand, straight, ciliated, and tapering to a 
sharp point. The caudal appendages are long, reaching 
to nearly the same distance ; their branches are generally 
free from hairs, and are styliform. The terminal plate is 
lanceolate, squamiform. 
This species is very free from colour, except the eye, 
which is of a deep purple, but, under the microscope, 
the animal appears to be rough on the surface, an ap- 
pearance due to a number of scale-like elevations of the 
skin. Under a power of about 300 diameters, the in- 
tegument of the body of the animal appears to be 
covered with minute distant scales ; they gradually in- 
crease and thicken, until they assume their greatest degree 
of number and character upon the anterior segments of 
the tail, and then again gradually decrease in size and 
importance towards the posterior extremity of the ani- 
mal. 
The first specimen which we received was sent to us 
by Mr. Edward, of Banff, who took it in that locality. 
It has since been procured by Mr. Gregor, from the 
stomach of a haddock, taken from about thirty or forty 
fathoms, near the same place.
