Genus PJiymactis Milne Edwards, 1857. 



Aciinia (pars) Dana, 1846. 

 Fhijmactis Milne Edavards, 1857. 

 Cladactis Verrill, 1869 (non Panceri). 

 Eucladadii^ Verrill, 1899. 



Aliciidae with the margin provided with acrorhagi; column wall 

 entirely covered with closely-set simple or Compound hollow tubercles. 



The determination by Carlgren (1899) of the true systematic 

 Position of this genus and the more perfect description of the tj'pe 

 species have reduced Verrill's genus Cladactis and his later Sub- 

 stitute EucladacHs to the rank of Synonyms, for they seem to possess 

 no peculiarities sufficient to Warrant their retention as distinct from 

 Phymactis.
