with a retractile presetai lip; an oval dorsal 

 cirrus at distal end of first and all subsequent 

 feet; ventral cirri similar to dorsal ones. Superior 

 setae include one or two long tapered capil- 

 laries serrated at base of blade and one or two 

 shorter forked setae with subequal prongs 

 Hanged on inner margins. Inferior setae com- 

 pound with bidentate falcigerous blades varying 

 in length. 



Remarks. — The only other species of Proto- 

 dorvillca recorded from the Atlantic coast of 

 United States is P. niiiiiita Hartman from deep 

 waters off New England. It is easily distin- 

 guished by its minute papilliform palps. Hobson 

 (1971) has rede.scribed the type of Staaroce- 

 plialiis kvfcrstcitii Mcintosh from Scotland and 

 her account shows that P. biartlrnlata Day 

 from South Africa is synonymous. P. gracilis 

 (Hartman) from California and P. ircupcrata 

 Banse and Nichols from Puget Sound are jjrob- 

 ably synonyms of P. keferstciiii too but Mrs. 

 Hobson has provisionally retained the name 

 P. (i)'<ici!is to cover both.
