number, in a transverse row on each side in each segment (xv, xvi, xvii). There are 
no nephridia on the parietes in front of the clitellum; behind, however, they are 
very numerous and very small, and form a transverse band (not a single line of 
nephridia) between the row of setae and the anterior septum of the segment. 
Testes and funnels are free in x and xi. The seminal vesicles, moderately large 
masses resembling bunches of grapes, are in xi and xii, attached to the anterior 
septum. 
The prostates are limited to xvili, and consist of a mass of small roundish 
lobules closely packed together into a solid-looking mass. The muscular duct, wider 
at its termination than at its beginning, passes straight inwards. 
Ovaries, with moniliform branches, and funnels are present in xiii. An addi- 
tional pair of small ovaries but no funnels were seen in xiv. 
The spermathecae (fig. 33) are two pairs, in viii and ix. The ampulla is ovoid 
in shape; the duct is as long as the ampulla and less than half as wide. The diverti- 
culum, arising from the termination of the duct, is club-shaped ; in length it reaches 
to about the middle of the length of the ampulla, z.e.is nearly 2 as long as outer and 
ampulla together ; its cavity is simple. 
There are no penial setae. 
Remarks.—The present species has no marked peculiarities, except the form of 
the male genital field; it is difficult therefore to assign it to any definite position 
within the genus, but it may perhaps be allied to M. insignis Mchlsn. (12). 
Megascolex konkanensis, Fedarb var. longus, var. nov. 
(Plate IX, figs. 34-35.) 
Parambikulam, 1700-3200 ft., Cochin State; 16—24-ix-1914 (F. H. Gravely). Two specimens, 
with perhaps a posterior fragment of another. 
External characters.—Length 345-570 mm., maximum diameter 3 mm. in one, 4 
mm.theother. They are thus extraordinarily long and (relatively) thin worms. The 
anterior end does not taper, but appears as if suddenly cut off; the front portion of 
the body is flattened, but behind the first third it becomes cylindrical, and much 
narrower (about 2 mm. only). Colour grey, within parts a bluish or slaty mottling. 
Segments of longer specimen, estimated, after counting the anterior third, 550; of 
the shorter, estimated, after counting the anterior half, 400. 
Prostomium bent downwards within the buccal cavity; proepilobous, with in 
addition two short longitudinal grooves continued backwards a little distance on the 
dorsal surface of the first segment. 
First dorsal pore in furrow 5/6. 
The setal ring is broken dorsally, in front of the clitellum, so that 22 = 3yz 
approximately, but the ratio varies, not so much on account of the width of zz as of 
that of yz, which is irregular. Behind the clitellum the break is absolutely and rela- 
tively less, so that 22 — 14yz; further back the ring is closed dorsally. Ventrally, in 
front of the clitellum aa=2ab; behind, aa = 34ab (3ab to 4ub at various parts).
