Ninoe (p. 2G6) 



Genus Lumhrineris Blainville, 1828 



Lumbriconereis Grube, 1840; = Lumbrinereis Delle Chiaje, 1841. 



Type (herein designated): Lumbrineris ebranchiata (Pallas, 1788). 



All the species represented have the prostomium conical to rounded, 

 without appendages, without eyes. Ventrally a pair of buccal cush- 

 ions or palps present. Proboscis with paired ventral mandibles 

 fused medially, with slender bases and flaring anterior ends (fig. 69, 

 h,i). Maxillae I, the forceps, stout, hooked, with short, broad 

 maxillary carriers (fig. 69,h,j).

hooded hooks or crotchets (fig. 67,6,c); acicula yellow 2
