336 The Rev. Lansdown Guilding's Account 



pedes antici graciles, breves, laeves, digitis hirsutis : cauda 

 articulo ultimo maximo latissimo. 



The male of the only species at present known is tolerably 

 well figured and described in the Zoological Miscellany of my 

 much esteemed friend Dr. Leach. Fabricius seems to have 

 suspected Pactolus Boscii, or some similar crab, to have been the 

 female of L. sagittaria. I possess both sexes of the new species 

 here described, and am therefore able to correct his error. It is 

 necessary to make the following correction of Leach's generic 

 character. 



Cauda maris 6-articulata : femina 5-articulata, articulo ultimo 

 fere magnitudine corporis (quod mirum), reliquis minutis.
