FAMILY HESIONIDAE 

 Key to genera and species 



1 Eight pairs of tentacular cirri; [3 antennae. Proboscis with 



marginal papillae but no jaws. Notopodium vestigial with 



few setae (Gjipti!^)] G. vittata 



r Six pairs of tentacular cirri 2 



2 A median and two lateral antennae. [Proboscis with marginal 



papillae {Opltiodrannis)] O. oh.scunts 



2' No median antenna, only two laterals 3 



3 Palps biarticulate. Notopodium reduced to an aciculum in 



dorsal cirrophore and usually a few setae (Nereimyra) N. pimrtata 



3' Palps not articulated. Notopodium a small but distinct lobe 

 on dorsal cirrophore bearing several setae (Pamhesiouc 

 lu tenia ) No. N.C. record

 c, d.

 Beaufort in 10-20 m (18, *). 



DlstrU)iitii>ii. — Maine to North Carolina; inter- 

 tidal to 55 m. 



Reconl.'<. — Many records between Cape Hat- 

 teras and Beaufort; intertidal to 40 m (5, 11, 

 13, 15, 17, 18,20, *)

Reniai-k.^. — Dr. Pettibone, in a personal com- 

 munication, maintains that Podarke Ehlers 

 should not be regarded as a synonym of Opliio- 

 rfro/»».s Sars since the type species of Podarke, 

 (P. agilis) has nearly uniramous parapodia, 

 while the type species of Ophiodronm.^, {O. vit- 

 tatiis Sars = O. Jle.vuousitfi Delia Chiaje) has 

 parapodia equally biramous. However both 

 genera have three antennae and six pairs of 

 tentacular cirri in contrast to Gyptis, Nereimyra , 

 and ParaIie.^io)ie and, as noted earlier (Day, 

 1967), I agree with Dr. Hartman that Podarke 

 is a synonym of Opitiodronni.'i. The number of 

 setae in the notopodia is. I feel, of specific but 

 not generic importance.
