Hcport upon the Oligochaeta. 55 



(/*/ ---- 3:2:4:2:6. Width of ventral pairs diminished towards the 

 18 segment, dd -= ca. J /.i. 



Nephridial pores in the lines of setae c. 



Prostate pores in b. 



Spermathecal pores in b. 



Internal Anatomy. Septa 6/7-12/13 strongly thickened, 13/14 

 slightly thickened, 14/15 hardly thickened. 



Alimentary tract : A large gizzard in the 6 segment. No distinct 

 calciferous glands. 



Male organs : Prostates very long, thin tubular, wound, with 

 rather long and thin duct. Penial setae ca. 2 - l-2-4 mm. long and 

 proximally 60-66 p thick, straight, distally flattened and distinctly 

 broadened to a breadth of about Ol mm., and somewhat enrolled 

 from the edges to form a chisel ; distal tip a little narrowed, ending 

 in a sharp concave edge. The distal two- third parts, with ex- 

 ception of the distal tip, are ornamented ; they bear densely crowded 

 transverse rows or ringlets of fine and slender spinelets. 



Spermathecae : Ampulla pear-shaped, rising from the upper part 

 of the hinder side of a thick cylindrical duct, the free proximal 

 extremity of which is rounded and represents the single diverticulum. 

 The ampulla contains a number of small seminal chambers embedded 

 in the thick wall. 



CHILOTA PRIESTI, Mich., f. MINOR, n.f. 



Loc. Knysna forest ; Dr. P. Purcell, leg. 



External Characters. Length 100-140 mm., thickness 4 mm., 

 number of segments 112-126. 



Clitellum at the 13-16 segments (= 4), ring-shaped. 



Seminal furrow laterally convex, passing the 18 segment laterally 

 from the setae ab, which are normally developed. 



Copulatory organs: Paired copulatory cushions at the 10, 11, 12 

 and 21 segments, an unpaired one at the 18 segment. 



Internal Anatomy apparently like that of the typical form.
