1015.] J. STEPHENSON : Indian Oligochaeta. 51 
The diverticula of septum 9/10, which pass backwards as elongated sacs, and in 
which the male genital products are formed, reached as far as segment xii, xiv, or xv. 
After crossing segment x each sac passes dorsal to the gut underneath the ovarian cham- 
ber representing segment xi, previously described. Thesac is quite free, and does not 
fuse with the floor of the chamber; the ovarian chamber can be cut through in the 
middle line and lifted up quite clear of the subjacent structures. On opening the 
posterior swollen end of the sac I did not discover a testicular vesicle,—7.e. a second, 
closed sac within the bag-like diverticulum of 9/10; the testis and developing genital 
products appeared to me to lie free in the cavity of the diverticulum itself. 
_The prostate (male atrium) is an ovoid mass, with its long axis antero-posterior, 
conspicuous on the body-wall, taking up the length of segment x; it is joined by the 
vas deferens on its anterior face. The ovaries are crescentic fringes on the anterior 
wall of the ovarian chamber (segment xi), lying alongside and underneath the arch 
of the nephridium. 
The shape of the spermathecal atrium varies. It may project upwards, papilla- 
like, from the ventral body-wall; or it may appear as an ovoid structure, with its 
long axis antero-posterior, sessile on the body-wall ; in these cases the duct joins the 
atrium not on its upper surface but at the middle of its height. Or it may be 
embedded in a recess in the body-wall,—easily defined and isolated but not projecting, 
its surface being flush with the inner surface of the parietes. 
Remarks.—Drawida ghatensis is thus a variable species. After dissecting the first 
example, I thought it would be necessary to erect a separate variety for it, on the 
ground, principally, of differences in the gizzards and spermathecal atrium. In no case 
where these features were examined, do they correspond with the condition described 
by Michaelsen; but neither do they agree among themselves. A comparison of the 
original description of the species with the above notes will show a few other differ- 
ences, though none of much importance. 
Drawida brunnea, sp. nov. 
Parambikulam, 1700-3200 ft., Cochin State; 16—24-ix-1014 (F. H. Gravely). A single specimen. 
Length 40 mm., maximum breadth 5 mm. Ashort, relatively very broad, dorso- 
ventrally flattened worm, perhaps much contracted antero-posteriorly as all the seg- 
ments are very short. The colour is a very dark brown, almost black, dorsally, and 
very slightly lighter ventrally. Segments 120. Prostomium not recognizable. 
Dorsal pores apparently absent. The setae are very small and very closely paired; 
they are difficult to detect in the anterior part of the body, and I could not distin- 
guish them at all in segment ii. Setae cd are in the lateral line of the body: and 
since the mid-ventral interval is rather less than the ventro-lateral, aa <1/6 circum- 
ference, bc >1/6 circumference. 
The male apertures are in furrow 10/11; they are bordered by prominent lips, 
which are swellings of the margins of the furrow. ‘They are situated midway between 
b and c, or rather nearer to c. 
There was no clitellum, and no other genital apertures were visible. From an
