Polyclrrus eximius 



Polycirrus eximius is a surface deposit-feeder that typically inhabits 

 empty gastropod shells, crevices in other calcareous material, or the empty 

 tubes of other polychaetes and hence its abundance may be directly related 

 to the availability of this material within subtidal sediments. Polycirrus 

 ranked among the top four at only EF during 1983 and was among the top ten 

 at only one other station (JC) . This species has been a consistent 

 component at all subtidal stations except IN, although densities in 1983 at 

 GN were generally lower than those previously obtained. At EF and other 

 stations as well, this species is frequently most abundant in September 

 (Fig. 13 M) . During the last six years, densities were highest from 

 September 1979 to September 1980. The 1983 densities, at all stations, were 

 comparable to those found in the past, and there have been no consistent 

 increasing or decreasing trends in density at any of the stations. 



Lumbrincris tenuis 



Lumhrineris tenuis is a motile deposit-feeder that ranked fourth in 

 abundance at JC during 1983 and was among the top ten at only one other 

 station (GN) . Densities at JC and GN were comparable to each other despite 

 their differing ranks. This species has been a relatively consistent 

 member of all subtidal communities except IN, with densities usually 

 highest at JC (Fig. 13 N) . Since 1976, the abundances of this species has 

 varied between years at GN, but remained relatively stable at JC. The 1983 

 values at JC were consistent with those obtained during the last six years, 

 while those at GN were among the highest recorded at this station since 

 1976. 



Polydorn caulleryi 



Polydora caulleryi is a tube dwelling polychaete which can obtain food 

 through either surface deposit or suspension feeding. Polydora ranked 

 third in abundance at JC and was among the top ten at both GN and EF during 

 1983. At these stations, annual densities in 1983 were well above those 

 obtained in recent years; this increase was primarily due to the unusually
