similar to those of the former species. The first pair of 

 legs ill the male are fully half as long again as the body ; 

 those of the female, which are slender, about the length 

 of the body ; the arms, wrists, and hands are tuberculo- 

 carinated. The remaining legs are slender, shorter and 

 smaller in proportion, than in H. aranem ; the third joint 

 with a line of small tubercles above. The abdomen re- 

 sembles in each sex that of the former species. The colour 

 of the carapace and legs above is reddish-white, the tu- 

 bercles a beautiful pink or rose-colour ; the under parts 

 dirty white. The dimensions of a fine male taken at Sand- 

 gate by myself, are as follows :

It is remarkable that in Dr. Leach's plate of this species, 

 the figure of the male is very much smaller than that of 

 the female. In the specimens which I have taken, the 

 contrary has been generally the rule, and the males have 

 been much larger than those figured by him. 



This species was discovered by Dr. Leach in the Frith 

 of Forth, and afterwards found by him on the southern 

 coast of Devon. I procured it at Hastings. Mr. Eyton 

 sent it to me from the coast of North Wales ; Mr. Couch 

 from Cornwall, and Mr. Dixon from Worthing. Dr. 

 Leach mentions Sandgate as a particular habitat, where 

 I also obtained several specimens by dredging, in May. 

 I have received it through the kindness of Mrs. Tate from 

 Zetland, and from Orkney by Dr. Pollexfen and Dr. Du- 

 guid. As an Irish S23ecies, it has occurred at Youghall, 

 in Dalkey Sound near Dublin ; in the loughs of Strangford 

 and Belfast, and at the Giant's Causeway. " Thus,"* says
