WESTWOODILLA CCECULA. 157 



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 inflexed against the 

 hand. The first two pairs of walking legs are uniform 

 in shaj^e, 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 are 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.
