. * In each of the subdivisions of the biological part, the different groups of 
Vermes are treated in the same order as in the Systematic part of the Record, 
except under the headings “Sense Organs,” " Variations,” and “Distribution of 
Parasitic Forms according to their Hosts,” where this arrangement was deemed 
undesirable.
