some new Species of Drawida. 519 



in this respect. The atrial or copulatory pouches are large, 

 flattened autero-posteriorly, slightly bifid at the top. They 

 occupy the greater portion of somite 7, in close relation with 

 the lateral longitudinal vessel. The cavity of the pouch is 

 nan-ow and irregular, and is lined by a columnar layer 

 of glandular cells with large nuclei at the base. The cavity 

 extends right up to the bifid ends of the pouch. The layer 

 of circular muscles and the external layer of cells form a 

 dense investment, which accounts for the compact texture of 

 the organ. In sectional preparations the cavity was found 

 full of granular material, some staining deeper than others, 

 composing sperma and a mucous base. 



Here is further evidence in support of my view that the 

 atrial pouch, wherever one is present in Drawida, acts as a 

 magazine of sperma, besides discharging a secondary 

 secretory function. 



The Nephridial System, which is meganephric, is not 

 distinguislied by any of tiie characters described in con- 

 nection with D. soinavarpatana. 



The Nervous System and Sensory Organs do not call for 

 any comments. The latter are filiform cells associated with 

 the perception of movement, occurring largely on the 

 prostomium and anterior somites. 



Remarks. — I am unable to state precisely the nature of 

 the function of the thick cutaneous humour, which is 

 probably protective. At the time of collecting, which was 

 after a slight drizzle in the morning, the worms were found 

 either crawling about or climbing dense herbage, from which 

 most of my specimens were taken. 



Locality. Bhagamandala, 4000 ft., Coorg, S. India. 



Type in the British Museum. Syntypes in the Indian 

 ]\Iuseum, Calcutta, and the Central Co lege, Bangalore, and 

 Hamburg Zoological Museum. 



Draic'ida elegans, sp. n. 



External Characters. — Length of preserved specimens 

 135 mm. ; fully stretched live specimen 155 ram. ; maxi- 

 mum diameter in the preclitellar region 7 mm. and behind 

 5 mm. Number of segments 200. The preclitellar somites, 

 which are strongly telescoped, are three times as long as the 

 postclitellar ones. All the segments bear annular ridges, on 

 which the sctffi are placed. These ridges are inconspicuous 

 on the hinder somites, which become extremely short in 

 front of anus. 



Prostomium long and prolobous.
