R( niarkn. — TerebeUa liiinnd-vumutd has 

 been well described and illustrated by Ehlers 

 (1887) and his description agrees in detail with 

 the description of TcnbcUa ptrrocliuitn 

 Schmarda, given by Day (1967). Both have 2 

 pairs of branched gills, noto.setae with narrow 

 wings and denticulate tips, and 16 ventral pads. 

 T. hrinu'D-CDwata has 27 segments with noto- 

 setae and uncini with three ai'cs of close-set 

 denticles while T. pterochaeta has 28-33 seg- 

 ments with notosetae and uncini with a crest of 

 close-set denticles. Both characters are variable 

 in the genus and the number of arcs of denticles, 

 which are always irregular and integrated, is 

 never clear. The two appear conspecific and 

 Schmarda's name has priority. As He.ssle (1917) 

 has defined the genus Terebella with two or 

 three pairs of branching gills, I see no point in 

 referring this species to Amphitritides Augener.

Terebella rubra (Verrill. 1873) (Homonym) 



Lepraea rubra Verrill, 1873a: 321 (iioii Tere/)( lla

 Terebella ?v/6r«. -Hartman, 1945: 44; 1951: 112.- 



McCloskey, 1970: 28. 



Remarks. — Hartman, (1959a) reported that 

 Terebella rubra (Verrill) is a junior homonym. 

 I have not seen a specimen but the published 

 descrij^tions state that it has three pairs of gills, 

 that the notosetae continue to near the end of 

 the abdomen, and that individual notosetae do 

 not possess a spur at the base of the denticu- 

 lated blade. These characters suggest that 

 Verrill's species must be close to T. elirciibergi 

 Grube from the Indo-Pacific and T. scliDiai'daei 

 Day from South Africa. Dr. Pettibone has sug- 

 gested that the type be examined before it is 

 renamed.
