. Annotationes zoologicae japonenses / Nihon do?butsugaku iho?. NEW OR IMPERFECTLY KNOWN SPECIES OF EARTHWORMS. 19 VII XVII XVIII 3. Fig. 9. 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 mm. on the median line of segment VII (fig. 9). In this patch there are 16 small papillae, on which open the " capsulogenous ; 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 ; 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 Be
