NO. 3 HARTMAN : ORBINIIDAE, APISTOBRANCHIDAE, PARAONIDAE 215 



Scoloplos sensu stricto and Scoloplos (Nainereis) was thought to be in 

 the shape of the prostomium, pointed in the former and rounded in the 

 latter. 



Mcintosh (1910, pp. 494-521), in a monographic study for Great 

 Britain, attributed the family name Ariciidae to Audouin and Milne 

 Edwards, 1833, although it had not been so used before Malmgren, 

 1867. Mcintosh used Aricia Savigny to include A. cuvieri, A. latreillii, 

 A. norvegica and his three new species A. edwardsi, A. grubei and A. 

 armandi. Scoloplos was used only for S. armiger and Nainereis (sic) 

 for Scoloplos quadricuspida and S. mammillata (sic) (see alphabetical 

 list of names below). 



The most comprehensive study of the family was that by Eisig 

 (1914, pp. 153-600), who reviewed previous works and brought to- 

 gether a vast body of literature. He made detailed studies of organ 

 systems and identified many morphological and anatomical parts ; most 

 of the accepted terminology was initiated in this study. He described 

 species in the genera Nainereis (sic), Aricia, Scoloplos, Scolaricia, and 

 erected Theostoma. Since the study was limited chiefly to species in the 

 Mediterranean Sea, its generic and specific categories were accordingly 

 restricted. 



Chamberlin (1919, pp. 353-361) described species in four genera 

 and added Branchethus; which is now referred to Scoloplos (Leodamas) 

 Kinberg. Day (1954, pp. 21-23) added new species in two new genera, 

 Proscoloplos and Orbiniella. 



Fauvel (1927a, pp. 7-26) in the Faune de France gave keys to five 

 genera; included are seven species in Aricia, two in Nainereis (sic) and 

 single species in Scoloplos, Theostoma and Scolaricia. The first includes 

 Orbinia and Phylo as used herein, the second is here spelled Naineris, 

 and Theostoma is called Protoaricia (below). 



The generic name Aricia Savigny is preoccupied and has been re- 

 placed by Orbinia Quatrefages (Hartman, 1936, p. 32) ; the family 

 name ARICIIDAE was thus changed to ORBINIIDAE (Hartman, 

 1942a, p. 57). 



The oldest species, now known as Scoloplos armiger, was first named 

 Lumbricus armiger Miiller, 1776; it is now reported from widely 

 scattered geographic areas, including various parts of Europe, eastern 

 United States, Japan and parts of the Southern Hemisphere. The next 

 oldest, first described from Greenland as Nais quadricuspida Fabricius, 

 1780, is now known as Naineris and recorded from both sides of the 

 northern Atlantic Ocean. Most of the other species from Europe were
