[33] ANNELIDS OF PEOVINCETOWN, MASS. 731 



We found a few specimens of Gapitella, which we are not able to sep- 

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

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

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

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

 still another had capillary sette on seven segments, but there were a 

 few uncini in the seventh ventral ramus. 



Near high water mark, in sand.
