basally, tapered abruptly to slender tips. Extended proboscis cylin- 

 drical, with a circle of papillae around opening, smooth or with

 extremely variable, pale, tannish, yellowish to brown including dorsal 

 cirri, dusky, dotted or transversely banded with green or brown, eggs

Biology. — Found intertidally, on shells, under rocks, on pilings 

 along with tunicates, sponges, in roots of sea basket grass. Dredged 

 on bottoms of mud, gravel, stones, rocks, with shells, algae, bryozoan 

 nodules and especially abundant with sandy tunicates Amaroecium 

 pellucidum. Numerous small specimens and females massed with 

 green eggs were found during the summer months in the Woods Hole 

 region. According to Thorson (1946, p. 56), they spawn in May 

 to July.
