FAMILY GLYCERIDAE 

 Key to genera and species 



1 Superior setae as simple capillaries and inferior ones com- 



pound and spinigerous. Two presetal lobes (Glycera) 2 



1' All setae compound and spinigerous. One presetal lobe (Hcmi- 

 podiis). [Proboscideal papillae include both oval and digiti- 

 form types] H. roseus 



2 Gills present but sometimes small and retractile. Parapodia 



with two postsetal lobes 3 



2' Gills entirely absent. One or two postsetal lobes 4 



3 Two separate cirriform gills, one on dorsal edge of para- 



podium and one on ventral edge Gh/ccra dibmiicliiata 



3' One retractile branching gill arising from posterodorsal base 



of foot; [postsetal lobes subequal] Glycera unicrinnia 



4 Superior presetal lobe minute. [Papillae on proboscis long 



and smooth] 5 



4' Superior presetal lobe at least half as long as inferior one 6 



5 Prongs of jaw support deeply notched, almost separate Glycera papillosa 



5' Prongs of jaw support only slightly notched, almost fused Glycera capitata 



6 Jaw support deeply forked, forming two slender divergent 



prongs 7 



6' Jaw support completely fused forming one asymmetrical piece. 



[Papillae on proboscis with 8-10 rings] Glycera oxya pliala 



7 Papillae on proboscis smooth 8 



7' Papillae on proboscis with 14-16 rings. [Parapodia with one 



emarginate postsetal lobe (Glyc( ra tenuis)] No N.C. record 



8 Two low postsetal lobes or one emarginate lobe on all feet Glycera tesselata 



8' One low postsetal lobe on first few feet, dividing to form 



a conical superior lobe and a low rounded median posterior 



lobe on subsequent feet Glycera asym Dutrica 



Hemipodus roseus Qualrefages, 186.'> Description.— Body slender, uniformly pale 



in alcohol, 15-38 mm long by 0.8 mm wide with 

 Figure 6a-c 80-100 segments. Prostomium as a slender cone 



with about 10 indistinct annulations and 4 small 



Hem/podM.s ro.sf'M.s. - Arwidsson, 1899: 28, pi. 2: terminal antennae. No eyes. Proboscis with 



Fig. 23, pi. 4: Fig. 58. - Hartman, 1950: 81 smooth papillae of two types (Figure 6b); 



(table of characters). numerous shorter tongue-shaped forms and 



HemipodH.s foorm//.s'.- Hartman, 1950: 81; 1968: fewer digitiform papillae about five times as
