The male pores are rather tumid, but have no papillae. They are 

 separated by 10 setae. 



The gizzard lies in VII and IX. 



The intestine commences in XV. It has cacae which arise in 

 XXVI and continue forward into XXV, where the end is slightly 

 curled round. 



There are hearts in XI, XII, XIH. 



In segments VII, VIII, and IX are three pairs of spermathecEe. As 

 there is no intervening septum between the last two, they lie very close 

 together. They are long pear-shaped bodies, gradually narrowing to 

 the duct which bears near the opening a small diverticulum on a long 

 duct which in some cases is arranged in a zigzag. 



Small sperm-sacs are found in XI, XII, and XIII. 



The spermiducal glands have a sac and a coiled duct ; the lobes of 

 the glands extend through three segments, viz., XVII — XIX ; they 

 are loose and comparatively thin. 



The dorsal pores are not very obvious, but do not commence till 

 XVI— XVII. 

 Habitat: Travancore.
