Adult Female. Carapace strongly vaulted, proportionately short and deep; seen from above 

 and with pseudorostrum included scarcely half as long again as broad; seen from the side (fig

 line and is not even quite horizontal seen fromabove (fig. 2 a) it is acutely triangular, seen from the sid<

 The dorsal part of the three anterior tree segments nearly or totally overlapped by the carapace : the two ante- 

 ments with -omewhat protruding dorsal lamellae. Abdomen slender and very conspicuously shorter 

 than the carapace.
