DcxrriptiiDt. — Body yellowish green, up to 

 150 mm long. Segments short, rounded dor- 

 sally, and flattened ventrally. Prostomium 

 bluntly conical, without eyes but with diffuse 

 daik pigment. Peristome fused to prostomium, 

 rather long and irregularly wrinkled but not 

 segmented. A transverse row of about 20 grooved 

 tentacular filaments above junction of setiger 

 1 to 2. A median gap in tentacular row 

 separating right and left groups. Cylindrical 

 (not grooved) gill filaments from .setiger 1 (thus 

 anterior to tentacular filaments) to posterior 

 part of body. Gill filaments, even of middle seg- 

 ments, arise immediately above notosetae. Cap- 

 illary setae in both rami of all segments. 

 Yellow acicular spines quite distinct in both 

 rami of posterior segments but longer and more 

 like capillaries in anterior feet; spines distinct 

 in juveniles from notopodium of setiger 85 and 

 neuropodium of setiger 19 but not distinct in 

 adults in anterior third of body. 



R<t)ia)-ks. — Verrill's description is not clear 

 regarding the origin of the first gill filaments and 

 the tentacular filaments. As noted by Day ( 1967: 

 500) the tentacular filaments arise from the 



posterior dorsal margin of the peristome. In 

 CirriforDiia this peristomial projection extends 

 further back than the first setiger which bears 

 the first pair of gill filaments; in Cirmtnlus the 

 first pair of gill filaments arises at the same 

 level as the tentacular filaments. In Cirriformia 

 grandis the tentacular filaments arise just pos- 

 terior to the gill filaments on setiger 1 so that 

 this species is a link between the two genera. 

 In Ciiivtidiis cirmtiis (Miiller) the tentacular 

 filaments arise above the gill filaments on setiger 

 1. Thus Cirriformia graiidi^ and Cirratiilus 

 cirratus are very alike in this respect, but 

 C. cirratiis can easily be distinguished by the 

 fact that in the middle of the body the gill 

 filaments arise at least as far above the noto- 

 setae as the distance between the notosetae 

 and neurosetae.
