REVISION OF PILARGIDAE — PETTIBONE 195 



Small specimens from Old Tampa Bay, Fla. (86 segments, 22 mm. 

 long, 0.3 mm. wide, figs. 2lb-d) showed the dorsal cirri longer, digiti- 

 form; neuropodia with 3 acicula, 2 of which project bej'ond setal lobe, 

 with slender capillary neurosetae. 



Distribution: Widespread in tropical and subtropical waters. 

 North Pacific (ofl:" Japan, southern to Lower California, Panama), 

 Central and South Pacific (Marshall Islands, Tuamotu Islands, 

 Gambler Islands), Red Sea, Indian Ocean, North Atlantic (Canary

Genus Harpochaela Korschelt, 1893 



Harpochaela Korschelt, 1893. [Type-species: H. cinguLala Korschelt, 1893, by 

 monotypy. Trieste, Italy, in plankton. Gender: feminine.] 



Diagnosis: Body elongated, with segmentation well marked. 

 Prostomium rounded, with paired ventral palpostyles, 3 antennae and 

 2 eyes. Tentacular segment with 2 pairs of tentacular cirri. Para- 

 podia subbiramous. Notopodia with dorsal cutI and emergent, 

 notopodial, hooked setae beginning at about setiger 5. Neuropodia 

 conical, with capillary, simple neurosetae, with ventral cirri. Tentac- 

 ular, dorsal and ventral cirri jointed. Pair of short anal cirri. 

 Larval organs consisting of prototroch, telotroch, larval organs in 

 prostomium and pygidium. 



Remarks: Harpochaeta has been referred by some authors to 

 Ancistrosyllis. However until the adult of the only known species, 

 H. cingulata, has been identified, it is difficult to know to what genus 

 Harpochaeta should be referred. Of the known genera, it might be 

 referred to Sigamhra Aliiller, 1858, Ancistrosyllis Mcintosh, 1879, or 

 Cabira Webster, 1879.
