The prostomium was proepilobous in some specimens. 
In front of the clitellum the ventral break in the setal ring 
was small, equal to 2ab or 3ab, and the ventral setae were numer- 
ous and closely set at slightly irregular intervals; the dorsal break 
was irregular, and both it and the intersetal distances on the dor- 
sal side were greater than the corresponding intervals on the ven- 
tral side. Behind the clitellum aa is very regular, and equal ap- 
proximately to 2ab; the dorsal break is about the same size as 
the ventral, and is also pretty regular. 
The clitellum includes 4 of xiii and 2 of xix—6. Dorsally 
the greater part of xiii is discoloured, and xix is not included ven- 
trally,—indeed in the midventral region xvii and xviii also want 
the purple colour which distinguishes the clitellum in general. 
Setae are distinguishable ventrally in xvi, xvii and xix, and less 
easily in xv and xiv; there are two or three on xviii between the 
male pores. 
The most conspicuous genital markings were a pair of concave 
sucker-like discs, circular and sharply delimited, in 16/17, the in- 
terval between them being equal to the diameter of one of the 
discs. In addition there were smaller eye-like markings in 19/20, 
20/21 and 21/22, circular, flat, not raised, with dark centre and 
lighter periphery; they may be surrounded by a slight groove. 
The interval between those of a pair is small, — aa only; in an 
antero-posterior direction they take up the posterior and anterior 
thirds of the segments bordering the grooves on which they lie. 
In some specimens these markings were only present on 19/20 and 
20/21. In one specimen there were similar markings on 14/15 and 
r5 16 also. 
The large firm barrel-shaped gizzard I find to be in segment v, 
though the septa in this region are not easy to distinguish. The 
first well-marked septum is 4/5, a stout sheet of tissue behind the 
pharynx, convex backwards; 7/8 is also thickened; and between 
the two there is certainly one extremely tenuous septum (6/7), as 
well as, in front of this, an extremely fine membrane around the 
gizzard,—a delicate bag in which the gizzard is contained, which 
is probably septum 5/6. 
Wegascolex konkanensis, Fedarb. 
Trivandrum, 1911 ; numerous specimens taken on several occasions. 
Out of a large number of examples a very few showed the full 
development of the male genital field. This I should describe as 
follows :— 
‘ On the flattened ventral surface of segment xviii are two 
large shallow depressions, oval in shape, with clean-cut margins 
and slightly prominent lips; the lips approach each other in the 
midventral line, where they are separated only by a median groove. 
The breadth of segment xviti is increased by the presence of these 
depressions; they encroach slightly on xix, and more on xvii; the 
axis of the oval is a little oblique, being directed forwards and
