1915.] J. STEPHENSON : Indian Oligochaeta. 61 
glands are a pair of structures in segment vii, one on each side, in shape an elongated 
and rather flattened ovoid, and lying obliquely in the segment so that the anterior 
end is more external; in the natural condition this position is probably represented 
by saying that the glands are flattened between the cone-like septa 6/7 and 7/8. 
The gland is bound to the parietes by a quantity of connective tissue; there is no 
trace of its being bifid; its surface is however mammillated, or composed of a num- 
ber of small slightly projecting lobules. The duct is given off from the under portion 
of the gland; it is short, moderately stout, and opens apparently ventro-laterally on 
the surface,—at a rough guess, as seen from inside, about one-third of the circum- 
ference from its fellow of the opposite side. 
Remarks.—When I first examined this form I had no doubt that it was a dis- 
tinct species, since the large atrial gland of the spermathecal apparatus was a single 
undivided structure on each side; in the other species of the genus these glands are 
double on each side. But the dissection of the other specimens of the genus con- 
tained in the present collection has rendered necessary a revision of my first impres- 
sion; as has already been seen, in one of the specimens which I refer to M. deshayesi, 
the double character of the glands was obvious, and each portion had its own stalk 
leading to the common atrium ; in the other specimen the double nature of the glands 
was much less apparent, and could only be demonstrated at the cost of some damage 
to the glandular mass. Since therefore the division into two of the organ seems 
to vary in its completeness, the purely single character of the gland in the present 
specimen is of less importance; and since there are no other considerable differences 
between the two forms, it seems best to be content with establishing a variety for 
the present example. 
Subfamily MEGASCOLECINAE. 
Genus PLUTELLUS. 
Parambikulam, 1700-3200 ft., Cochin State; 16—24-ix-1914 (F. H. Gravely). A single specimen, 
but unfortunately immature, wanting spermathecal and seminal vesicles; the species is there- 
fore indeterminable. 
Genus PONTODRILUS. 
Pontodrilus bermudensis, Bedd. f. ephippiger (Rosa). 
Ennur backwater, Madras; 18-i-1915 and 21-i-1915 (N. Annandale). Several batches, taken on 
separate occasions. 
Pontodrilus agnesae, sp. nov. 
Horton Plains, Ceylon, 7000 ft.; in crevices of quartz. Dec., 1913 (S. W. Kemp). Three speci- 
mens, none complete ; two of them represent the anterior end, one the posterior. 
Elk Plains, Nuwara Eliya, Ceylon, 6200 ft., Dec., 1913 (S. W. Kemp). One complete though 
damaged specimen; one fragment incomplete at both ends. 
External characters.—Length 65 mm., diameter (average) I mm.; colour dark 
brown. Segments II6. 
Prostomium prolobous, but the groove marking off the prostomium is slight, so 
that the condition is almost zygolobous.
