ON SOME EARTHWORMS PROM INDIA. 433 



There is only one gizzard, but B. schlegelii is stated to only 

 have one. 



The oviducal pore is single, which is also the case with B. bolavi 

 and B. gracilis. 



The calciferous glands of this species are peculiar, occurring only in 

 segment XV, and not being simple pouches on the side of the oeso- 

 phagus but more elaborate lobed structures. .No other Benhamia has 

 glands like this. 



Habitat : Travancore. 



2. Benhamia travancorensis, n. sp. (PI. I., Figs. 6, 8, 9, 11, 12.) 



It is 75 mm. in length and 2 mm. in breadth. It has 131 segments. 



The clitellum extends from XIV to XXI. It is saddle-shaped, 

 having a ventral line not thickened. 



The setae are in pairs very close together. 



The dorsal pores commence posteriorly. 



The pharynx is very large. 



There are two gizzards in VIII and IX. They are more or less 

 cylindrical, the posterior one is somewhat flattened ventrally. 



There are calciferous glands in XIV, XV and XVI. 



They are pouch-shaped, somewhat corrugated, the anterior being 

 the smallest. 



The intestine commences in XVIIand has no caeca. 



The last hearts occur in XIII. 



The nephridia are diffuse. 



There are two pairs of spermathecae in VIII and IX. Each has a 

 constriction dividing the pouch from the pouch-like duct which bear 

 the diverticulum. 



The sperm-sacs in XI and XII are very minute. 



The spermiducal glands in XVIII and XIX are within the clitel- 

 lum ; they are tubular and fusiform. 



They have a bunch of penial setae at the mouth. 



These are about four times as long as the ordinary ones, and 

 terminate in a fine whip-like end frequently bent into a hook. 



No ventral pairs of setae occur on XVII, XVIII, or XIX. 



In many respects this worm resembles Benhamia kafuruensis . 



Septa IX to 5JV are thickened. 



Habitat : Travancore.
