XVIII 



12. P. micronaria, n. sp. 

 Length 66 mm., breadth 3 mm , number of segments 106. Clitellum 



XIV — XVI, without seta;. Number of setae 

 in the spermathecal segments 28-32, more 

 posteriorly 35. First dorsal pore in XI/ 

 XII. Spermathecal pores 4 pairs in V/VI 

 — VIII/IX ; no genital papillœ in tìàs region. 

 Sperm duct pores large, on top of papillae, 

 separated by 8 setae; two pairs of genital 

 papillae in XVII 1 just inside the lines of the male pores, each pair close to the 

 intersegmental lines. 



Intestine begins in XV ; one pair of intestinal cœca in XXVI, extending for 

 two segments anteriorly. Thickened septa V/VI— VII/VIII and X/XI— 

 XII/XIII. Spermathecae 4 pairs, in VI— IX ; only the pair in VIII with 

 minute diverticula. Ko ovisac. Prostate gland in XVII — XX. Testes in X, 

 XI ; sperm reservoirs in XI, XII, comparatively small. Last heart in XIII. 

 Loc. — Tokyo. 



VII 



Iii. P. vittata, n. sp. 

 Length 100 mm., breadth 6 mm., number of segments 68. In the dorsal 



aspect, the chaetal lines are light grey and 

 the rest dark brown, thus appearing banded; 

 in the ventral view of uniform light grey. 



VIII 



«®» 999 \ Cbtellum flesh-red, XIV— XVI, without 

 setœ. Number of setae in III 35, in VII 57, 

 in VIII 59, in XVIII 60. First dorsal pore 

 in XIII/XIV. Spermathecal pores 6 pairs, on lop of papillœ, 3 pairs in both 

 VII and VIII, those of the same segment being situated in the same transverse line 

 and in front of the chœtal Une.* Sperm duet pores could not be detected exter- 

 nally. 



Intestine begins in XVI ; one pair of intestinal cœca in XXVI, with five 

 secondary cœca, of which the most dorsal is longest and the more ventral ones gra- 



* The punctatecTcircles in tbe accompanying cut represent the spermathecal openings and 

 not genital papillre, as might be inferred from analogy with other cuts.
