Living and dead individuals of this species are found with low 

 frequencies in traverses 2 and 4 as well as at stations 98 and 17.

 Buccella frigida (Cushman) Andersen, Journ. Washington Acad. Sci., vol. 42, 



No. 5, p. 144, figs. 4a-c, 5, 6a-c, 1952. 



This species is very common in L.I.S. Living and dead specimens 

 are found at almost all stations. The living population has its maxi- 

 mum frequency on the north side of traverses 2 and 3 about 3-5 miles 

 offshore at a depth of 15-25 m. In traverse 4, B. frigida is more 

 abundant, and the living population is developed on both the north 

 and south sides of the Sound. The frequency distribution of the 

 total population has fewer maxima and usually makes up 20-30 per- 

 cent of the total population in the offshore stations.
