This species is translucent to opaque in appearance. It is finely 

 perforate, and only some individuals have retral processes. The 

 translucent individuals can be easily confused with E. pauciloculum 

 or E. tisburyense, whereas the opaque individuals with retral proc- 

 esses can be confused with opaque specimens of E. clavatum. This 

 species does, however, from a distinct recognizable morphologic group. 

 Moreover, the wall structure of E. varium is granular, whereas the 

 other species of Elphidium in L.I.S. are all radial. 



This species is common in all areas of L.I.S. but usually comprises 

 less than 10 percent of the total population. Living individuals were 

 found in all areas with low frequencies. Some of the living individ- 

 uals were found in cysts composed of quartz and organic matter.
