is somewhat differently shaped in the two forms, having in 

 de Haan's figure straight sides, whereas in Upogcbia capoisis 

 the telson is broader in the upper half than in the lower, the 

 diminution in width taking place rather abruptly near the 

 middle. Krauss states that the colour of the Cape species 

 when alive is bluish green, after drying turning reddish- 

 yellow. He found it common in Table Bay, and Dr. Gilchrist 

 informs me that it is very abundant in some of the " Vleis " or 

 salt water lakes of the colony, the specimens sent being from 

 Zwartkops River, Algoa Bay. Stimpson's Gehia subspinasa 

 from Simon's Bay has the legs of the first three pairs armed 

 near the base with a sharp spine, which is wanting in the 

 species described by Krauss.
