The species of Clypeaster in this collection seem to represent but a single species 



(except possibly one of the very young ones), and we refer them with little doubt 



to this form, which Doderlein found not uncommon in Sagami Bay. They range 



from 14 to 114 mm. in length, and the largest is 108 mm. wide and 24 mm. high.
