but very prominent wall. The two walls meet at the median ventral line, sur- 

 passing at the other side the lines of setae b. The area is some- 

 what prominent round the centre, depressed at the periphery. 



Internal Anatomy,— Septa 4-5 and 8-9 — lo-ii very strong, 

 5-6 — 7-8 missing, 11-12 and the following tender. 



Alimentary tract: A big gizzard between septa 4-5 and 8-9. 

 Gßsophagus with globular swelling in the 12th segment (containing 

 probably a pair of calciferous glands^). Intestine beginning in the 

 15th segment, laterally sacculated in the anterior part, with a big 

 simple typhlosole, triangular in transverse section, with a broad 

 base, beginning about the 26th (?) segment. 



Circulatory system: Dorsal vessel simple ; last hearts in the 

 13th segment. 



Nephridial system micronephric. 



Anterior male organs: One pair of great sperm-duct-funnels 

 ventrally in the nth segment, enclosed in a common seminal vesicle 

 which communicates with a pair of large, much lobed sperm-sacs, depending from 

 septum 11-12 into segments 12 — 14. 



Prostates tubular, with a very long, coiled glandular part which occupies about 

 three segments, and a thinner, but still moderately thick, very much shorter, but 

 relatively long, muscular duct which describes an S-like curve with a longer proximal 

 end. 



Penial setae (fig. 63) about 4 mm. long and 20 fx thick, nearly straight. Distal 

 end not at all broadened and only very little, if at all flattened, ending in a rather 

 blunt tip. The ornamentation is restricted to some rather indistinct triangular teeth 

 sparsely distributed over the part of the seta below the extreme distal end. I could 

 not detect these teeth on all penial setae I examined more carefully. 



Spermathecae (fig. 62) : Main pouch with a broad and very short ampulla which 

 is divided by some more or less distinct longitudinal incisions into some broad protuber- 

 ances ; the latter are not simple, but bear a great number of small nearly circular 

 protuberances. The duct of the main pouch is about half as thick as the ampulla and 

 nearly three times as long as the width of the proximal part, not tapering before the 

 end of the distal third part. The main pouch has in all the form of a mushroom. 

 Into the proximal part of the duct of the main pouch open two diverticula which are 

 situated neither opposite nor just abreast of each other. The diverticula are broad, 

 short, unstalked, irregular knobs containing from three to five globular, glittering 

 seminal chambers which cause slight protuberances on the surface of the diverti- 

 cula. 



Hab.— Central India, United Provinces, Kalwari Bazar in the Basti 

 district; DHARM KHAN leg. 



^ As I did not wish to damage the single mature specimen more than was absolutely necessary, I 

 did not open the oesophagus to confirm this point.
