Fig. 6. Metafolliculina nordgardi showing: A. a, 
peristomal lobes; h, body; c, lorica; d, body attachment 
point; and e, base of lorica. B. a, nucleus. C. a, peri- 
stomal lobes; b—c, second extension; c—d, first exten- 
sion; and e, present body attachment point. 
builder of the original lorica also adds exten- 
sions this method of counting may or may not 
result in a correct whorl number. 
Although these possibilities of accounting for 
neck extension place in question the limited 
alternatives of older theories, the process must 
be observed in many species before these pos- 
sibilities can be accepted unequivocally.
