Family XIII. ASTROPECTINID^ Gray (restricted). 



Family XIV. LUIDIIDAi Verrill = Luidiince Sladen. 



It will be noticed that in the above arrangement the family Arch- 

 asteridise of Perrier, 1894, is divided among five distinct families 

 and subfamilies. Most of his genera are now placed in the Pseud- 

 archasterinae. 



The subordinal name Valvata I have here changed to Valvulosa, 

 partly because it is not strictly identical with Valvata of Perrier, 

 and partly to make its termination correspond with Paxillosa. 



In the arrangements of Perrier, and of Sladen, Valvaster is made 

 a subfamily, Valvasterinae, of the family Echinasteridae. Fisher
