[33] ANNELIDS OF PROVINCETOWN, MASS. 731 



We found a few spccimeus of Capitella^ which we are not able to sep- 

 arate from C. cajpitata. Sexual setse on the eighth and ninth segments; 

 all segments before the eighth with capillary setae only; after the ninth, 

 with unciui only. On one young specimen capillary setae were found 

 only on three segments. Another had five segments with capillary setae ; 

 still another had cai)illary setae on seven segments, but there were a 

 few uncini in the seventh ventral ramus.
