ON SOME EARTHWORMS FROM INDIA. 431 



The seise are not continuous. There is a ventral gap of about the 

 space of three setae, while the dorsal space is much less. But quite at 

 the tail end of the animal — segment 170th —this arrangement is 

 obliterated, where there are 24 setae equidistant. 



The clrtellum obviously extends from XIV — XVI, and the setae 

 show through. There is a large area on XIV, in a line with the setae, 

 bearing the oviducal pore. The modified tissue of the clitellum, 

 which Gan only be distinguished with the microscope, extends as far 

 forward as to just in front of segment X and backwards to XX. 



The male pores are borne on two large papillae, the width of the 

 segment, with no setae between. 



The dorsal pores commence IV — V. 



The pharynx is large. There are a pair of mucous glands in V. 



There is a large gizzard in VI. 



There are no calciferous glands. 



The oesophagus is small till segment XVI. 



The intestine commences in XVI in two large pouches. 



There are hearts in XII and XIII. 



In segments VIII and X[ are two pairs of spermathecse. 



The pouch is pear-shaped with a very delicate duct about the same 

 length. A club-shaped diverticulum, the length of the duct, joins near 

 the aperture. 



Segments XI and XII each possess a very well developed pair of 

 sperm-sacs. They are very racemose indeed, the divisions being 

 almost globular. 



The spermiduGal glands are very peculiar and have a mop-like 

 appearance. The duct is straight and has no muscular sac. The 

 distal end seems dilated into a sac from which arise numerous simple 

 filiform processes. In a younger specimen the gland appeared like a 

 tube with many transverse branches at the end. 



Habitat : North Konkan and Travancore. 



5. Perichceta travancorensls, n. sp. (PL II, Figs. 2, 5.) 



This worm has 94 segments. It is 70 mm. long and 4 broad. 



Its anterior dorsal surface is purplish, which colour behind the 

 clitellum narrows to a strip. 



The clitellum extends from XtV— XVI. The area round the 

 feirale pore is much marked.
