Report upon the Oliyochaeta. 47 



part of the 9 segment laterally of and close by the lines of the 

 setae b. 



Internal Anatomy. Septa 6/7-13/14 thickened, 9/10-11/12 rather 

 strong. 



Alimentary tract : A large gizzard in the 5 segment. No 

 calciferous glands. 



Male organs : Two pairs of spermiducal funnels free in the 10 and 11 

 segments. Two pairs of grape-like sperm-sacs in the 11 and 12 seg- 

 ments at the septa 10/11 and 11/12. Prostate confined each to 

 one segment ; glandular part thick and narrowly serpentine ; duct 

 short and thin. Penial setae in two different forms : (1) slender 

 form very long (ca. 1*75 mm.) and extraordinarily thin (ca. 7 ^), 

 thread-like, only a little bent, quite smooth, if not ornamented by a 

 small number of short and clumsy, slightly bent teeth ; distal tip 

 simply pointed; (2) clumsier form ca. 0-9 mm. long, and proximally 

 9 ^ thick, distally thinner ; slightly bent ; distal part with 

 exception of the slender and simply pointed tip ornamented by 

 widely and irregularly scattered rather large and clumsy teeth, 

 which are placed at the proximal end of longitudinal scar-like 

 recesses, and form the distal end of longitudinal convex pro- 

 tuberances ; these longitudinal recesses and protuberances being 

 placed alternately at two sides of the seta, the latter appears to 

 be sepentine at the distal half. 



Sperrnathecae : Ampulla slender, sac-shaped, opening through 

 a very short conical duct : into the latter open two rather large 

 club-shaped diverticula with short and narrow stalk, and not quite 

 as long as the ampulla ; seminal chamber of the diverticula not 

 quite simple, but with slightly folded walls.

Setae ventrally widely paired, dorsally very widely paired; ab 

 somewhat diminished towards the male pores ; aa > be > cd == ca. 

 1J- 2 ab ; del = ca. p. 



Clitellum ring-shaped at the 14-16 segments, covering also small 

 parts of the 13 and the 17 segments. 



Prostate pores at the 17 and 19 segments in b.
