MONOCULODES CARINATUS. 167 



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 wrist, 

 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.
