collar, appears as a large spongy mass, in which it is mostly impossible to discern cell 
boundaries ; each funnel is larger in section than the alimentary tube, the space 
between which and the lateral body-wall it entirely fills out. The lumen is small, 
excentric, nearer the inner side of the funnel ; the cells of which the mass is composed 
appear, so far as they can be distinguished at all, not to radiate directly outwards 
from the lumen to the periphery, but to be disposed in a spiral manner. 
Sperm morulae are free in large numbers in xi; septum 10/11 is much bulged 
forwards, so that segment x is almost non-existent as a cavity in the mature animal 
(cf. fig. 4.) The vas deferens is an extremely fine much coiled tube situated in the 
ventral portion of xii; the amount of coiling is illustrated by the fact that it may be 
cut about 16 times in a single section. 
The penial body (fig. 5) isa small compact ovoid structure, with a muscular or 
fibrous capsule; strong strands pass dorsally and laterally to the body-wall. The 
mass lies to the inner side of the penial lumen, which latter extends upwards and out- 
wards beyond the point where it is joined by the vas deferens. The cells of the bulb 
do not extend on to the body-wall; but I am unable to give more precise details of its 
structure since the condition of the specimens scarcely permits of refined histological 
study. 
The ovaries and detached ova are present in segment xii; funnel and oviducts 
were not distinguished. 
The spermathecae have the usual situation. The ampullae are ovoid in shape, 
situated dorsally somewhat above the level of the oesophagus, with which their lower 
ends are continuous; though the cells of the one organ are continued into those of the 
other I did not make out an actual continuity of the lumina of the two. The epi- 
thelium of the ampullary wall consists of columnar cells of variable height, but mostly 
considerably elongated, with granular protoplasm and basally situated nucleus; 
owing to the height of the cells the cavity is relatively small. At the upper end where 
the duct takes origin the walls are thinner and the elongated granular cells have dis- 
appeared. The commencement of the duct is invaginated into the cavity of the am- 
pulla ; its first portion continues the direction of the ampulla obliquely upwards 
towards the dorsal body-wall; it then bends downwards and outwards to open on the 
lateral surface in about the mid-lateral line of the body. ‘There are no gland cells 
round the aperture.

Kavalai, 1300-3000 ft., Cochin State ; 24—27-ix-1914 (F. H. Gravely). Two specimens. 
Forest tramway, mile 10-14, alt. 0-300 ft.; Cochin State; 28 --29-ix-1g14 (F. H. Gravely) Two 
specimens. 
This species has recently been described by Michaelsen (12); it will therefore 
suffice to draw attention to a few differences between his specimens and mine, and to 
mention a few additional facts of structure.
