that species showed that L. hancocki was distinct from the Pacific 

 species. 



The holotype has faded to an even cream color, with one large pair 

 of dark pigment spots on the carapace, and scattered chromatophores 

 on the carapace and the remainder of the body. There is also an indica- 

 tion of a large pigment spot on the anterolateral portions of the telson.
