96 Memoirs of the Indian Museum. [Vou. VI, 
dial condition, determined me to give the above description. The condition of the 
nephridia may be compared with that in Megascolides hastatus. 
Megascolex cochinensis, sp. nov. 
(Plate IX, figs. 32-33.) 
Forest tramway, mile 10-14, alt. 0-300 ft, Cochin State ; 28—29-ix-1914 (F. H. Gravely). Two 
specimens. 
External characters.—Length 175-220 mm., diameter 4 mm.; colour an equable 
light grey, nonpigmented. Sue 224. 
Prostomium epilobous 4—4, the ‘ tongue’ being cut off behind. 
The dorsal pores begin in rohe 5/6. 
The setal rings are broken; dorsally zz =2yz, ventrally aa = 2ab or rather morein 
front of the clitellum, and = 3ab behind it. The setae are closer together ventrally; 
the intersetal intervals are not very regular, so that the setae are not arranged in 
longitudinal series. The numbers counted were 41/v, 54/ix, 57/xii, 48/xix, and in the 
middle of the body 36 and 38. 
The clitellum, extending over xiv—?xvii (= 32), is smooth; setal rings and 
dorsal pores are present on it. 
The male pores (fig. 32) on segment xviii, are elongated wavy slits, obliquely 
disposed, their posterior ends nearer the middle line than their anterior. These slits 
are situated each on a white oval elevation, the long axis of each elevation being 
oblique and corresponding with the slit, so that the hinder ends of the elevations 
approach one another, or almost touch in the middle line. . Around and between 
these oval papillae the surface is depressed and darker; and surrounding the whole 
is a well defined wall, the ‘moat’ between papilla and wall being deepest anteriorly 
(fig. 32). The centres of the male apertures are about ,4 of the circumference 
distant from each other. 
The female aperture is indicated by an oval patch with its long axis transverse, 
whitish in colour, mid-ventrally situated in the line of the setae of xiv; its lateral 
extent is from a to a or slightly more. 
The spermathecal apertures are transverse slits with distinct anterior and pos- 
terior lips, in 7/8 and 8/0, in line with a; each is surrounded by a small area rather 
darker in colour than the surroundings. 
Internal anatomy.—Septa 4/5 and 5/6 are thin, 6/7—11/12 moderately and 
12/13 —13/14 slightly thickened. 
The gizzard, in v, is large and ieee aed: There are no calcareous glands, 
but the oesophagus is swollen and vascular in xii, xiii and xiv. The intestine begins 
in xix. 
The last heart is in xiii. 
The excretory system is micronephridial. There are the usual tufts, here very 
large, by the side of the oesophagus behind the pharynx, and similar tufts are con- 
tinued backwards between the successive cone-like septa for some distance behind the 
gizzard. In the clitellar region the nephridia appear as bushy tufts, about six in
