from one-fifth to one-sixth the length of the total 

 radioles. The ends of the radioles surpass the 

 ends of the distal pinnules. Ventral nude fila- 

 ments were not seen. 



The collar (Figures 8b and 8c) is oblique, with 

 entire margin. The first (buccal) segment is 

 invisible and the collar is not clearly set off from 

 the first setiger; the border can be recognized 

 only in stained material. The thoracic and 15 

 to 20 anterior abdominal setigers are clearly bi- 

 annulate; after staining also the following ones 



appear divided. Ventral shields are absent. A 

 thick glandular postsetal girdle is present on the 

 second setiger. Dorsally in the thorax, the in- 

 trasegmental borders bend rearward similar to 

 C. magna (cf. Figure 5e). Rings of elevated 

 whitish tissue, presumably glandular, are pre- 

 sent in the presetal annuli of the thoracic setigers 

 and in the presetal and postsetal annuli of the 

 anterior 15 to 20 abdominal setigers. The ring 

 on the second thoracic setiger is ventrally ex- 

 panded (Figure 8b). Except on the second se-
