There is a fine series of this species in the present collection, 

 ranging from 5'5 to 16 mm. across the disk, with arms 6-7 times 

 as much. They show little diversity, among themselves, all having 

 the small nearly circular radial shields and the naked disk skin 

 characteristic of the species.
