what resembling the fore feet of a mole : legs ten, each furnish- 

 ed with a small subulate claw ; the two posterior pairs appear 

 to be natatorial, and are so extremely hirsute as to be almost 

 concealed : the tail, or posterior part of the body, is also 

 covered so closely with hair as to render the extreme joints in- 

 distinct; at the extremity are two long setiform appendages 

 tufted with hair, which are capable of closing together instan- 

 taneously. 



Length of the body about four lines. 



Colour yellowish-white : the hair and divisions between the 

 joints partake most of the former. 



This very curious species of Cancer was first discovered on the 

 large scallop, Pecten maximns, from Salcomb, but appears ex- 

 tremely rare. 



Cancer Gammaeus eubricatus. 

 Tab. V. Fig. 1. 



Body slender, compressed, with twelve smooth joints : anten- 

 nas four, the lower pair shortest, the upper nearly as long as the 

 body : eyes crimson, reticulated, sub-angulated, and rather pro- 

 truded forward between the upper and lower antennae : arms 

 four, similar; hands small, oblong, and sub-cheleferous ; fangs 

 hooked : legs ten, the two anterior pairs short, the others consi- 

 derably larger, all beset with bristles, especially at the joints : 

 caudal fins two pairs, the last joint bifid ; above these, two very 

 short appendages. 



Length half an inch. 



Colour usually reddish, or pale pink, minutely and closely 

 speckled with a darker shade of the same. 



This species, which is not common, approaches much nearer 

 to Cancer Vulex than any other: independent, however, of its 



^ being
