182 Memoirs of the Indian Museum. [Vol,. I, 



Alimentary tract: A big gizzard in the 6th (5th?) segment. (Ösophagus 

 simple, without set-off calciferous glands, a little swollen in the 

 13th segment (and in some neighbouring ones?). Intestine with a 

 small, indistinct typhlosole, — apparently formed only by the immer- 

 sion of the dorsal vessel. 



Circulatory system: Dorsal vessel simple ; last hearts in the 

 13th segment. 



Nephridial system: In each segment behind the cliteUar 

 region is found a pair of meganephridia besides a number of micro- 

 nephridia. In the more anterior segments only micronephridia were 

 seen. 



Anterior male organs: One pair of sperm-duct-funnels free in 

 the nth segment. One pair of grape-like sperm-sacs depending from 

 septum 1 1- 1 2 into the 12th segment. 



Prostates: Glandular portion consisting of two irregular disc- Fig. 15. 



shaped broadly united parts, each of which has some more or less '^^^* " ^-^ ""^^^ "" 

 deep incisions. Duct arising from the medial incision between these two parts of 

 the glandular portion, rather thin and long, irregularly undulating. There are no 

 penial setse. 



Spermathecae (fig. 19) : Main pouch with a pear-shaped ampulla, which 

 distally passes without distinct break into a slender duct, about twice as long and 

 proximally about half as thick as the ampulla, tapering at the distal end. Beneath 

 the proximal part of this duct two club-shaped or nearly tubular diverticula, which 

 are about half as long and thick as the duct of the main pouch, open opposite to 

 each other. The greatest proximal part of the diverticula is occupied by a simple 

 seminal chamber. (The spermathecae of this species are nearly equal to those of 

 H. vilpattiensis.) 



Hab« — South India, Tiger Shola (near Kodaikanal) in the Palni Hills, 

 virgin forest, 5,500' ; Dr. J. R. HENDERSON leg., vi-1907.

 Present one much softened specimen. 



External Characters. — Dimensions : I^ength 180 mm., thickness about 5 — 6 

 mm., number of segments about 240 (in large parts of the body only roughly counted) ; 

 hinder end regenerated, with very short segments.

 pecially the median ones), and more distant from one another. Antechtellar circles
