OLIGOCH^TA. 271 



The vesiculgg seminales are paired, in segments XI. and XII., 

 comparatively small in size, not lobnlated. The prostates are 

 lobiilated, and occupy four segments, XVIII.-XXI. ; the duct is 

 stout, originates hi XIX., and runs obliquely forwards to open in 

 XVIII. 



The ovaries are large, and are situated, with the ovarian funnels, 

 in segment XIII. 



The spermathecas (fig. 13) are two pans, in segments VII. and VIII., 

 opening in the furrows 6/7 and 7/8. The ampulla is somewhat 

 flattened, irregularly circular and sac-Uke ; the duct is very broad, 

 and nearly as long as the ampulla, from which it is not sharply 

 marked off. The diverticulum is very small, club-shaped, and 

 arises from the junction of ampulla and duct. 



The genital setse (fig. 14) are in length • 94 mm. , m breadth 16-18 [x. 

 The distal end is curved through about the quadrant of a circle, is 

 tapermg and pomted , and is ornamented by a single circle of minute 

 sculpturings at the commencement of the terminal curve. 



Pheretima hawayana, (Rosa). 



For reasons to be subsequently assigned, I give an account of 

 some of the anatomical features of the single specimen of this species 

 in the present collection. It was found, along with the six species 

 of Megascolex, in the rotten wood of dead tree stumps and logs in 

 the jungle, at Pattipola (hill country), Cej^lon, 6,000 feet. 



External Characters. — Length 2 inches; breadth 2 1/2 mm. 

 Colour yellowish brown. Segments 91. 



Prostomium epilobous 1/2. 



First dorsal pore in intersegmental furrow 10/11. 



The ditellum comprises segments XIV. -XVI. =; 3 ; it is annular 

 in form, and has a few small setae ventrally on segment XVI. only. 



The male apertures are on segment XVIII., widel}^ separated, and 

 not elevated. There are twelve setse intervening between the 

 apertures ; these setse however do not approach very near to the 

 inner margins of the apertures themselves. 



The female aperture is presumably situated in a small, mid- ventral, 

 somewhat transversely extended depression on segment XIV. 



The spermathecal apertures were invisible from the exterior. 



Genital markings were present in the form of a number of spots to 

 the inner side of the male apertures. These were of a dark colour, 

 and were, I think, somewhat depressed, certainly not elevated. 

 There were four such spots on the left, and two on the right side, in 

 a transverse line slightly behind the level of the male apertures, and 

 therefore behuid the level of the setse. A minute darkish spot was 

 also visible ventrolaterally on the left side of segment VIII., just 

 in front of furrow 8/9.
