24 MAIAD.E, 



the greater part of the hmhs, is covered with a close, short, 

 villous coat ; and the anteniiEe, rostrum, and all the tu- 

 bercles are furnished with tufts of long, curved, club- 

 shaped hairs. Underneath this covering the shell is po- 

 lished, and minutely punctured. The colour is a dull red- 

 dish-brown, becoming bright red by boiling, or by the 

 action of spirit. The general length of the carapace in a 

 full-grown male is two inches three lines, breadth one 

 inch six lines. 



The babits of this species, as ftir as I have had an op- 

 portunity of observing them, are curious. They are found 

 concealed under the lonof hansinff fuci which clothe the 

 rocks at some distance from the shore, in which situation 

 I have taken them amongst the Bognor rocks. They con- 

 gregate in vast numbers at the place I have just mentioned, 

 in the prawn and lobster pots. I have seen, probably, 

 thirty amongst the refuse of one of these, attracted no 

 doubt by the garbage which is placed in them as bait. 

 These were much larger and finer tban any I have seen 

 elsewhere. Contrary to the comparative sizes of the two 

 sexes, as figured by Dr. Leach, I found the males larger 

 than the females, exceeding them in length by about half 

 an inch. Thus, Leach's figure of the male is not at all 

 equal in size or apparent strength to those which I found 

 at Bognor, but that of the female is about the ordinary 

 size of that sex. Like all the slow moving Crustacea, they 

 are very liable to be covered with small fuci, so that they 

 are sometimes completely concealed by a mass of these 

 marine plants growing upon their surface, where their 

 roots find a secure hold amongst the villous coat of the 

 shell and limbs.* This is especially the case with the
