site chosen, neck lengths varied only between 
132/x and l67g with the mean at approximately 
159 g. Spiral whorls ( d ) usually numbered six, 
although occasionally five and seven were ob- 
served. The diameter of the neck (49g) was 
approximately that of the unrestricted sac. 
In reflected light the color of the extended 
body resembled that of Parafolliculina violaceae 
(Matthews, 1962), except that perhaps in E. 
lignicola the wine color was somewhat more 
intense. However, in transmitted light the body 
and lorica appeared bottle-green, a characteristic 
of most folliculinids. As previously reported 
(Matthews, 1962), both size and number of 
nuclear components varied in accordance with 
body contraction resulting from fixation. Thus, 
in contracted bodies, nuclear components were 
large (5g) and often numbered as few as 6, 
whereas in more relaxed bodies, nuclear com- 
ponents (Fig. le) were small (3g) and often
