some new Sjyecies o/Drawida. 525 



opposite side by the dorsal and ventral mesenteries. They 

 occur throughout in all somites, except the first three 

 anterior ones. Tlie lobes of the integumentary nephridia 

 are whitish-looking mushroom-like structures composed of 

 twisted tubules, and are phiced on the seta-line ccl, where 

 they open along with the mcganephridia. The lobes of the 

 integumentary nephridia are a characteristic feature of the 

 internal surface of the body-wall in the opened specimens. 

 1 am not quite sure whether there are two independent 

 nephridiopores, and I have not succeeded in making out 

 how the integumentary tubule opens outside. The integu- 

 mentary nephridium has not a funnel-like nephrostone, 

 Avhichj however, is represented by a simple dilatation of the 

 inferior limb in the mid-ventral line. The ductules of the 

 integumentary nephridia are absolutely narrower than those 

 of the meganephi idia. 



The nervous system and sensory organs do not call for 

 any further remark than that the latter are in every respect 

 like those of D. somavarpatana. The nervous system is 

 more highly organised than in the case of the two foregoing 

 species described here. 



Locality. Bharramandala, 4000 ft., Coorg, S. India. The 

 type is in the British Museum ; syntypes with Prof. Dr. 

 W. M. Michaelsen, in the Indian Museum, Calcutta, and in 

 the Central College, Bangalore. 



Drawida modesta, sp. n. 



External Characters. — Length 72 mm., diameter in the 

 preclitellar region 6 mm. and in the postclitellar part 

 -Ji mm. ; number of segments 221, those of the middle and 

 the hinder part of the body are very short. 



The setffi are moderately large, closely paired, aa = bc. The 

 first somite is free from setae, dd is less than half the 

 circumference. 



Prostomium very small and prolobous. 



No dorsal pores. 



Clitellum well-marked over segments 10-13. The genital 

 markings are simple. The ventral part of somite 7, between 

 the sperraathecal openings, is hollow^, terminating on either 

 side anteriorly in a conspicuous oval grey glandular lobe of 

 skin, a feature Avhich I have not noticed in any other species 

 of Draivida with which I am acquainted. Around and 

 between the male orifices is a fairly deep oval groove. A 

 similar marking of grooves is present around the female 

 pores also. On somites 9 and 8 there are faint circular
