4 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 10 



1. Dorsal cirri reduced or absent a 



a. First pair of maxillae resemble forceps . Arabella Grube 

 (Ehlers considered 3 others in this category, including 

 Aracoda Schmarda, which is herein referred to Arabella, 

 also Laranda and Larymna, considered indeterminable.) 



b. Maxillae I do not resemble forceps ( 1 ) 



(1) Dorsal cirri reduced . . AT'o^oaVrw^ Schmarda 



(2) Dorsal cirri absent .... Notopsilus Ehlers 



2. Dorsal cirri foliaceous a 



a. Maxillary carriers long, slender ( 1 ) 



( 1 ) Prostomium covered by peristomium 



Aglaurides Ehlers 



(Includes Oenone Savigny, originally based on an 

 error.) 



(2) Prostomium not covered (a) 



(a) With one pair of eyes ; maxillae vs^ith 5 pairs of 

 dissimilar plates . . Cirrobranchia Ehlers 



(b) With 2 pairs of eyes; maxillae w^ith 6 pairs of 

 plates Dany/nene Kinberg 



b. Maxillary carriers short, platelike . Lysarete Kinberg 

 II. Parapodia biramous, provided with simple and composite setae . 



Eunice Prionognatha Dicopa 



(Includes only the Dorvilleidae, =Staurocephalidae.) 



Since this extensive classification was proposed, many genera have 

 been erected. To the family Onuphidae may be added (1) Nothria 

 Malmgren, (2) Epidiopatra Augener, (3) Hyalinoecia Malmgren, (4) 

 Leptoecia Chamberlin, (5) Paradiopatra Ehlers, (6) Paronuphis Ehlers, 

 (7) Paranorthia Moore, and (8) Rhatiiphobrachium Ehlers. To the 

 family Eunicidae are to be added (1) Palola Gray, (2) Paramarphysa 

 Ehlers, (3) Heterotnarphysa Verrill, (4) Lithognatha, and possibly (5) 

 Coelobranchus Izuka, an aberrant form. To the Lumbrineridae are to be 

 added (1) Cenogenus Chamberlin and (2) Augeneria Monro (see also 

 Aotearia Benham, p. 134). In the Arabellidae are to be added (1 ) Drilo- 

 nereis Claparede, (2) Biborin Chamberlin, and (3) Labidognathus Caul- 

 lery. 



In the Lysaretidae, Cirrobranchia is a synonym of Halla Costa, Dany- 

 mene is insufficiently known, and Iphitime Marenzeller is to be added. 

 Enonella Stimpson (1853) may be the same as Iphitime, but it too is in- 

 completely known. Pterothrix Chamberlin ( 1919, p. 325) is questionable, 

 since it is based on Notocirrus scoticus Mcintosh, which Fauvel (1923, 

 p. 451 ) believes to be based on pieces of 2 species in other genera.
