HARTMAN : POLYCHAETOUS ANNELIDS 



Aberrant parasitic genera are Haematocleptes Wiren, Labrorostratus 

 St. Joseph, Oligognathus Spengel, and Ophiuricola Ludwig. 



Diagnostic characters of the superfa7nily Eunicea. — The proboscis is 

 provided with a ventral mandible and dorsal maxillae. These parts are 

 usually corneous or also calcified and of diagnostic significance. The man- 

 dibles consist of a pair of flattened plates, more or less fused along their 

 median line. The dorsal maxillary pieces consist of several (to many) 

 pairs of pieces, including the maxillary carriers, with or without a ventral 

 median piece, and paired maxillae numbered from I to IV or V (or even 

 VI, but very numerous in the Dorvilleidae). Maxillae I may be falcate, 

 thus designated forceps, or have dentations along a longer or shorter por- 

 tion of the cutting length. Maxillae II are often the largest pieces and 

 sometimes called the major plates. Maxillae III and IV are sometimes 

 fused on the right side (characteristic for Eunicidae and Onuphidae) or 

 free from one another on both sides. The proboscidial armature is of 3 

 major kinds, as illustrated in ( 1 ) the Onuphidae, Eunicidae, and Lum- 

 brineridae, (2) the Arabellidae and Lysaretidae, and (3) the Dorvillei- 

 dae. In the first group the maxillary carriers are typically short, without 

 a ventral median, unpaired piece; in the second group they are long, 

 slender, with an unpaired piece; in the last group the entire maxillary ap- 

 paratus is strikingly different. 



In all the Eunicea the parapodia appear to be uniramous, but the noto- 

 podium is often represented (even in the Lumbrineridae) by a more or 

 less reduced fascicle of notoacicula, or also a dorsal cirrus. Setae consist of 

 one to many kinds, including simple or also composite ; they are character- 

 istic for family, genus, or species.
