WESTW OODILLA CCECULA.

gin, which is furnished towards the distal extremity with 
a copious brush of hair ; the finger is straight, and appears 
not to have the capability of being indexed against the 
hand. The first two pairs of walking legs are uniform 
in shape, and carry a tuft of hair upon the antero-distal 
extremity of the sixth joint. The fifth pair of legs are 
longer and more robust than the sixth. The coxa has 
the anterior lobe much deeper than the posterior. The 
sixth pair of legs ate rather longer than the preceding, 
and more slender ; whilst the seventh is considerably 
longer and still more slender, having the foot consider- 
ably increased in length, and the finger very long, being 
longer than the foot, and quite straight. The caudal 
appendages are nearly equal in length ; the last pair 
are rather more foliaceous than the two preceding pairs ; 
and the terminal plate is squamous, round, and dorsally 
concave. 
The animal is very transparent, being slightly corneous ; 
under the microscope the structure of the skin appears like 
a series of cells, overlapping each other like the scales of 
fish ; the margin of each scale is defined by a double 
row of short straight lines or spots, and a black spot 
marks the centre of each scale. The whole surface of 
the skin of the posterior part of the animal is, moreover, 
superficially covered with a fine fur, formed of processes 
of the integument, broad at the base, and exquisitely 
fine at the apex. The anterior portion of the animal is 
free from this fur. 
The specimen from which our figure was taken is a 
female, and laden with ova. We took it from among 
some trawl-refuse, brought in from the neighbourhood 
of the Eddystone. It has since been sent to us from 
the Moray Frith, by the Rev. G. Gordon ; and from 
Banff by Mr. Edward.
