Carapax convex; proportion of length to breadth, i : 1.5 1 ; areolets 

 indistinct ; surface smooth but somewhat uneven anteriorly, and 

 sparingly granulated toward the anterior margins. Antero-lateral 

 margin with four teeth, including that behind the angle of the orbit ;.

 the third and fourth. A small tooth on the subhepatic region be- 

 neath the postorbital tooth. Front somewhat deflexed, prominently 

 rounded and deeply emarginate at the middle ; margin minutely ser- 

 rated. Orbit with the hiatus of the exterior side distinct though, 

 narrow ; inferior margin denticulated ; tooth at inner angle promi- 

 nent. Subhepatic region granulated. A fringe of hairs around and 

 above the bases of the chelopoda. Surface of abdomen and ster-

 Heteropanope eucratoides Stimpson, Proc. Acad. Nat. Sci. Phila., x, p. 35; 



One specimen only, a male, of this species exists in the collection.. 

 The carapax is narrow, and resembles that of some forms of Gono- 

 placidae ; proportion of length to breadth, 1:1.25. Upper surface 

 somewhat uneven, especially anteriorly, where there are some trans- 

 verse, linear, pubescent ridges. Antero-lateral margin very much 

 shorter than the postero-lateral, with three prominent teeth besides 

 the little prominent anterior one, which is coalescent with the angle 

 of the orbit. These three teeth are acute, with convex sides ; the 

 middle one is smaller than the others ; the posterior one is placed at 

 a somewhat higher level than the middle one, and projects a little:
