Krauss agree in maintaining that this form has deluded their 
predecessors into supposing that the species of Matuta were 
swimming crabs. Riippell even supposes that no crabs properly 
deserve that appellation, but he feels sure that the sharp, flat- 
tened feet in Matuta are only to enable the creatures to slip 
easily into the sand. Ortmann, however (Bronn’s Thierreich, 
Vol. V., Pt. 2, p. 1232, 1899) assures us that he has himself seen 
Matuta swimming, shooting laterally through the water after 
the fashion of the Portunidae.
