range (see tabulation below). In the Texas area specimens were 

 collected from mud, sand, and shell (Kornicker and Wise, 1962). In 

 the "Gulf of Canso," Cushman (1906, p. 366) found specimens of 

 both sexes clinging to eel grass and hydroids (Pennaria tiarella). 



Food: A complete harpacticoid copepod (identified by T. E. 

 Bowman) was in the stomach of a juvenile female from the Point 

 Richmond area, Calif. The copepod contained some internal organs 

 indicating that it was swallowed alive. The relatively large size of 

 the copepod suggests that S. zostericola is capable of stretching its 

 esophagus to several times its relaxed diameter while ingesting prey. 



Behavior: Kornicker and Wise (1960) showed experimentally that 

 S. zostericola burrows more rapidly in silty sand than in oolitic sand. 

 Jones (1961, p. 290, table 2) reported that off Point Richmond, Calif., 

 92 percent of specimens of S. zostericola were collected in cores of 

 sediment at depths within the cores of 0-20 mm, 8 percent at 20-40 

 mm, and none below 40 mm, Jones (1961, p. 262) stated that speci- 

 mens in the core deeper than 20 mm were probably pushed to that 

 depth by the coring tube. 



The California Department of Public Health (1954) gives the en- 

 vironmental data from the vicinity of Point Richmond, Calif., as 

 follows : 



» Ostracods were collected on Sept. 14, 15, 1953, using an Ecktnan grab sampler. Ostracods were collected 

 from sediment samples, not water samples. 

 b Water samples were taken 3-4 feet below the surface with a Kemmerer water sampler. 

 « Number represents 25 samples at low tide and 25 at high tide from same stations.
