Report upon the Oiigochaetft. 57 



for a length of about 0'2 mm. flattened and broadened (40 ^ broad), 

 distally ending in an edge which is rounded at the side and deeply 

 incised in the middle. The whole seta is bent like a fishing-hook. 

 The more convex upper side of the middle part is ornamented by 

 transverse groups or rows of fine and slender spineless. Besides 

 this ornamentation the penial seta shows in its distal quarter with 

 exception of the flattened extreme distal end an annulation. depend- 

 ing upon the internal structure. 



Spermathecae : Ampulla egg-shaped, duct about one-third as thick 

 and half as long. Into the proximal part of the duct opens an 

 unstalked, nearly globular or thickly kidney-shaped diverticulum 

 which contains some rather large seminal chambers. These seminal 

 chambers may be seen externally, causing more or less distinct 

 flat protuberances at the surface of the diverticulum. 



CHILOTA FAUCIUM, n. sp. 



Loc. Table Mountain near Cape Town, Kasteels Poort Gorge ; 

 Dr. P. Purcell, leg. 



External Characters. Length ca. 30 mm., thickness ca. If mm., 

 number of segments 77-84. 



Head tanylobous. 



Setae at the ends of the body a little enlarged, in general ventrally 

 very widely paired, dorsally separated or nearly so. At the middle 

 part of the body cm : ab : be : cd == 24 : 13 : 18 : 17. Towards the 

 hinder end the width of the pairs enlarges still more ; towards 

 the 18 segment the \vidth of the ventral pairs diminishes slowly but 

 finally rather considerably, del -- ca. f p. 



Nephridial pores in the lines of the setae c. 



Clitellurn ring-shaped, at the 13 | 17 segments (== 4). 



Prostate pores upon small papillae between the lines of the setae 

 a and b, perhaps somewhat nearer to the latter. 



Spermathecal pores in b. 



Internal Anatomy. Septa 5/6 tender, 6/7-14/15 thickened, but 

 even the thicker middle ones not considerably. 



Alimentary tract : A small glittering gizzard in the 5 segment. 

 No distinct calciferous glands. 



Male organs : Two pairs of sperm-sacs in the 9 and 11 segments. 

 Prostates restricted each to one segment or to two neighbouring 

 ones ; glandular part serpentine ; duct short, strongly bent. Penial 

 setae ca. 1'2 mm. long and proximally 30 /.t thick, at the distal end 

 about 18 fj. thick, simply but strongly bent ; distal part flattened and
