LOG. Newlands slope of Table Mountain near Cape Town (types of 

 Acanthodrilus Purcelli). 



Table Mountain near Cape Town ; Dr. F. Purcell, leg. 



St. James, False Bay. 



Simonstown, at the waterfall. 



Remarks. Besides the statement of the identity of Chilota 

 Purcelli (Bedd.) and Ch. montanus, Mich., resulting out of the 

 comparison of the types, we need no further description of the 

 species, as we have already an exact one under the title of 

 Ch. montanu*.

External Characters. Length 42-52 mm., thickness, 2^-3^- mm., 

 number of segments 78-94. 



Head tanylobous. 



Setae ventrally widely paired, dorsally separated. In general 

 aa : ab : be : cd == 5:3:6: 6. Towards the 18 segment ab diminishes. 

 dd == ca. ^ p. 



Nephridial pores in c. 



Clitellum ring-shaped, at the 13-17 segments (= 5), only very 

 slightly developed at the 13 and at the 17 segment. 



Prostate pores in b. 



Seminal furrows nearly straight, slightly convex laterally. 



Spermathecal pores in b. 



Copulatory organs : A single unpaired copulatory cushion ventrally 

 at the 21 segment. 



Internal Anatomy. Alimentary tract : Gizzard rather large. 



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

 Prostates restricted each to a single segment ; glandular part coiled, 

 duct short and very thin, strongly bent. Penial setae about 1'75 mm. 

 long and proximally ca. 35 p thick, diminishing in breadth only a 

 little towards the distal end, being 20 p thick a little before the distal 

 tip. Middle part of the seta somewhat flattened, two-edged, with a 

 more convex upper side and a flatter under side. Extreme distal end
