The typical species of Eucratoplax A. Milne Edwards. E, 

 guttata, is identical with Eucratopsis crassinianus (Dana): 

 therefore Eucratoplax becomes a synonym of Eucratopsis. 

 The specimens in hand are. I think, referable to the second 

 species of Milne Edwards. Eucratoplax elata. which is here 

 assigned only provisionally to the genus Eucratopsis, as it 

 differs from the type species of the genus in haying the third 

 segment of the abdomen of the male extend to the coxae of 

 the fifth pair of feet. 



Eucratopsis data is known only from a brief diagnosis of 

 the female. Following is a description of specimens of both 

 sexes in the United States National Museum : 



Male. — Carapace subquadrate, convex, punctate, granulate
