banded, the intersegmental lines being of a'chestnut color (Saccardo) and the rest 

 of a light flesh color ; ventral side uniformly colored, the same as the light colored 

 portions of the dorsal side. Number of seta? in the spermathecal region usually 60. 

 Clitellum XIV — XVI, without seta?. Spermathecal pores two pairs, in VI/VII, 

 VII/VIII. There are no genital papilla? in this region, but there is instead a slightly 

 elevated modified patch of the integument of an elliptical form, of the diameter of 

 about 1.3 mm. on the median line of segment VII (fig. 9). In this patch there are 16 

 small papillae, on which open the " capsulogenous glands." Sometimes the posterior 



borders of the spermathecal pores are surrounded by 

 similar papilla?, in which case the patches occupied by 

 them are also modified. These papilla? are also the 

 openings of " capsulogenous glands." Male pores in 

 XVIII, separated by 19 seta?, of a transverse slit-like 

 form, on top of papilla?. There is a large circular 

 concave papilla of the diameter of about 1 mm. on the 

 median line in segment XVIII, close to its anterior border and even projecting into 

 the preceding segment ; in its centre is a small papilla on which open some " capsulo- 

 genous glands " (fig. 9). First dorsal pore in XII/XIII. 



Gizzard in Vili, IX ; intestine beginning in XV, with six pairs of cœca in 



XXVII. Thickened septa IV/V— 

 VI/VII and X/XI — XIII/XIV ; 

 septum VII/VIII exceedingly thin ; 

 septa VIII/IX, IX/X wanting. 

 Sperm reservoir in XI, XII. Ovisac 

 present. Spermatheca? two pairs, 

 in VII, VIII, with diverticula long- 

 er than the main portion and opening 

 near the middle of its tubular por- 

 tion. " Capsulogenous glands " ex- 

 ceedingly well developed : one group of 

 8 pairs in the median line in segment 

 VII (fig. 10), similar to what 

 obtains in P. Rohugo Bed. another
