336 The Rev. Lanspown GuizpiNc’s Account 
pedes antici graciles, breves, læves, 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. l 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: femine 5-articulata, articulo ultimo 
fere magnitudine corporis (quod mirum), reliquis minutis.
