STUDIES ON EARTHWORMS. 79 



I could find no male pores, but, curiously enough, the 

 pores of the oviduct are fairly evident. These are placed in 

 the groove between somites xii and xiii, one on each side of 

 the middle line. By means of a series of transverse sections I 

 found they were the external openings of the funnel-shaped 

 organ described and figured by me {" Studies on Earthworms," 

 No. I, PI. XVI, fig. 7) for M. Rappi, of the function of which 

 I was then doubtful. I believe now that this organ is the ovi- 

 duct, and that these pores are their apertures (PI. VIII, fig, 3, e). 

 The pores of the spermathecae differ in position from those 

 of the former species. They lie in a line with the nephridiopores, 

 usually one on each side, on the anterior edges of somites xi 

 and XII ; these pores I could see by the aid of a lens, after I had 

 found the spermathecse (fig. 3, b). 



The Internal Anatomy. — The general anatomy agrees 

 with that of M. Rappi, but one or two noteworthy differences 

 are presented. 



In the alimentary tract the only diff'erence is in the shape 

 and extent of the intestinal glands. In M. Rappi, the 

 gland on each side has the appearance of a rounded swelling 

 on the side of the intestine, which it partly covers dorsally, 

 and into the lumen of which the cavity of the gland opens by 

 a wide aperture. The gland occupies the whole length of 

 somite ix, and only a small portion of it lies in the preceding 

 somite (fig. 9). But in this new species the gland is bilobed, 

 being nipped, as it were, by the septum, which divides it into 

 two very nearly equal parts ; the larger lobe lies in somite viii, 

 the smaller lobe in somite ix. Moreover the gland is greatly 

 constricted off from the intestine (fig. 8) so that the commu- 

 nication between the two cavities is reduced to a small aperture. 

 The genital organs present several important differences. 

 Instead of two pairs of seminal reservoirs and of ciliated 

 rosettes, there is only one pair of each in this new species. 

 The seminal reservoirs lie in somite x, and the ciliated rosettes 

 in somite ix. In the three specimens opened the reservoirs 

 are small, looser in structure, and more irregular than in M. 

 Rappi ; in one case only is the ciliated rosette not enclosed in
