27. P. vsiculata, n. sp. 



Length 60 — 105 mm., breadth 3— 5 ram., number of segments 75 — 92. Setœ 

 65 in the spermathecal region, 77 in XII I, these numbers, however, varying accord- 

 ing to individuals ; more crowded on the ventral side, there being only 17 — 23 on 

 the dorsal side and 42 — 48 on the ventral side, in the spermathecal region. Clitellum 

 XIV — XVf, without setœ. Spermathecal pores two pairs, in VI/VII, VII/VIII ; 



no genital papillœ near them. Male pores in XVIII, 

 of the shape of transverse slits, close to the lateral mar- 

 gin of the body ; no genital papilla? near them (fig.

Gizzard in Vili, IX ; intestine beginning in XVI, with one pair of cœca with 

 4 pairs of secondary diverticula in XXVI ; of these diverticula the dorsal ones are 

 longest and reach segment XXIII. Septa all thin, none of 

 them being especially thickened ; septa VIII/IX, IX/X 

 wanting Sperraathecœ two pairs, in VII, VIII, with 

 spherical sacs and short ducts ; diverticula shorter than the 

 main portion but convoluted (fig. 14). Sperm reservoir in 

 XI, XII, lobed. Ovary and ovisac comparatively large» 



Prostate gland somewhat rectangular, in XVII — XIX. Sperm 

 duct with a' terminal sac (fig. 15). 



Externally this species closely resembles P. sexla Benham, 

 but differs from it in the position of the first dorsal pore, in the 

 number of setœ betweei the male pores, and several internal 

 characters. 



Loc. — Takahashi (Prov. Bitchü), Öarai (Prov. Hidachi).
