Pheretima feae (Rosa). 
Kawkareik, Amherst District, Lower Burma, 19—20-xi-1g11 (fF. A. 
Gravely). A single specimen. 
A glandular collar has previously been described round the 
oesophagus in segment x. This was seen to be a flange-like struc- 
ture behind the gizzard, against which it rests; since the flange 
is set rather obliquely, the appearance is not unlike that of a cup 
and saucer. Microscopically the collar was found to be composed 
of follicles of blood-glands like those described by Beddard (1) 
behind the pharynx in certain species of Pheretima and other 
genera. 
Pheretima lignicola, Stephenson. 
Thingannyinaung to Myawadi, Lower Burma, ca. goo ft., 24—26-xi-1911 
(F. H. Gravely). <A single specimen. 
Here also in segment x, behind the pharynx, there was found 
a ring-like or collar-Jike thickening of the oesophageal wall, soft and 
of an opaque yellow colour. On teasing a small portion and 
examining it microscopically this was, as in P. feae, found to consist 
of follicles of blood-glands. 
Pheretima trivandrana, sp. nov. 
(Platexxxil, fio 27 pl. sexi figs. 28420); 
Trivandrum, 23-vi-19g11. A single specimen. 
External Characters.—Length 70 mm., maximum diameter 3 
mm, Colour an equable grey. Segments 100. 
Prostomium epilobous 4, tongue broad, not delimited behind. 
The first dorsal pore is in furrow 8/9. 
In the first ten segments there is no dorsal break in the con- 
tinuity of the setal rings, but behind this there is a small interrup- 
tion (27—=2yz). The ventral break is also small (aa = ca. 1}ab), 
and in some of the anterior segments, v to vii, is altogether absent. 
The setae of segments ii-ix are rather enlarged, those on x rather 
small. The following numbers were counted :—28/v, 46/ix, 52/xii, 
52/xix, and 54 in the middle of the body. 
The clitellum was not distinguishable, except perhaps by the 
smaller size of the setae of segments xiv-xvi. 
The male apertures, on segment xvili, are fairly conspicuous 
pores in line with setae g.. They are situated towards the inner 
side of, but well within, a pair of circular thickened areas, some- 
what raised in their centres. The pores are slightly more than a 
quarter of the circumference apart, and four (right side) or five 
setae (left side) intervene between the pore and the midventral 
line.
