The gizzard is well-developed, barrel-shaped, in vi; in front of the gizzard the 
oesophagus is soft, dark and bulky. There are no calcareous glands; the oesophagus 
is dark, vascular and rather bulged in xiii—xvi. The intestine begins in xix. 
The last heart is in xiii. 
Micronephridia are present as large tufts at the sides of the oesophagus and 
gizzard, and throughout the anterior part of the body they appear as a single bush- 
like bunch laterally on each side in each segment, each bunch attached apparently 
to the body-wall by a single narrow stalk; there are none elsewhere on the body- 
wall, and there are no meganephridia. In the posterior segments the micronephridial 
tuft is still present; and in addition there is a relatively large (meganephridial) loop, 
intimately connected at its lower end with the tuft, which is here ventral in the seg- 
ment; the loop extends dorsalwards on the body-wall nearly to the mid-dorsal line. 
Testes and funnels are free in segment xi, none are present in x (confirmed on 
a second specimen). The seminal vesicles are one pair only, attached to the ante- 
rior wall of segment xii; they are small and grape-like. 
The prostate, in the specimen first dissected, was an elongated straight, narrow 
and somewhat flattened (‘‘tongue-shaped ’’) structure with smooth borders and taper- 
ing hinder end ; the duct was short, cylindrical and slightly glancing; the glandular 
_ portion extended back to segment xxi. The prostate of the second specimen however 
was coiled. One of the glands of the first specimen was examined microscopically ; 
the edge of the gland, under magnification, was seen to be cut up here and there by 
fine incisures. Transverse sections showed a minute, more or less central, lumen, 
round which the cells have an epithelial arrangement; and also numerous small ducts 
of similar structure in the substance of the gland, which unite with the central chan- 
nel; the main mass of the gland consisted of a compact tissue in which cell outlines 
were not visible under ordinary magnifications, but the specimen was not in good 
condition for histological details. 
The spermathecae lie in segments viii and ix; they are of simple form. The 
ampulla, in the specimen in which they appeared to be best developed, was elongated 
and cylindrical but bent once or twice on itself. A duct can hardly be described ; 
a single diverticulum rises from the base of the ampulla close to where it joins the 
body-wall; it also is cylindrical, is about two-thirds as long as the ampulla when the 
latter is straightened out, and about two-thirds as thick also. 
Penial setae (fig. 9) are contained in a sac which, situated to the inner side of the 
prostate, extends back as far as segment xxii. In length they are 3—3°5 mm., in dia- 
meter (at middle of shaft) ‘016 mm. They are almost straight for the greater part 
of their length, slightly bowed distally, and the terminal seventh is sinuous. The 
tip is excavated crescentically; the lateral margins of the extreme end are stouter 
than the central portion, which latter therefore forms a sort of web. Numerous fine 
sculpturings are present from near the tip to some little distance beyond the sinuous 
portion of the shaft; these are triangular with the point forwards; they do not seem 
to be spines, since they do not stand off from the side of the seta on focussing the 
margin ; they need the oil immersion lens to be well seen.
