of minute processes. Area II refers to the paired, dorsolateral bands; it 

 has several rows of conspicuous sets of pieces, arranged in oblique series. 

 In species where examined, it is possible to refer to these pieces in- 

 dividually, by numbering them from II-l to II-6, since each piece is 

 unique for the position it occupies. Area III refers to the paired, lateral 

 rows numbering one to several on a side; they are of a single kind and 

 usually small. Area IV refers to the paired, ventrolateral, one or 2 

 rows, and area V to the paired ventral rows, one on a side. Area VI 

 marks the midventrum and is bare in the species that have been ex- 

 amined. Organs on area V may also be lacking in some species. 



All proboscidial organs except those on area IV have an apical or 

 subapical (rarely basal) pore. Those on area IV are provided with 

 hard, spinous processes and appear to function perhaps in the same 

 manner as do the chevrons in species of Goniada (above). The organs 

 with pores have one or more spinous processes, directed straight or 

 obliquely back, toward the mouth when the proboscis is everted. Those
