This species was described by its author from a single 

 small specimen only 9 mm. long. In the "Endeavour" 

 collection there is a fine series of thirty-four specimens 

 ranging from 18.6 to 82.4 mm. in length of carapace. Some 

 modifications of the original description therefore need to 

 be made to fit the adult.
