just described, was present; its termination presented only two 
lobules and it was inserted into the main duct just below the 
ampulla. Microscopically, after clearing, the first kind of diverti- 
culum was found to be a simple tube, with the cavity wider at 
the free end. The second kind consists of several (three or four) 
elongated and irregular chambers, tightly bound together by con- 
nective tissue (fig, 29).

Kuching, Sarawak, 29-vil-1910 (C. W. Beebe). Two specimens, in bad 
condition. 
External Characters.—Length 136 mm., diameter 4.5 mm. It 
is impossible to say what the original colour may have been ; 
the clitellum is a medium brown. It would be impossible to esti- 
mate the segments without stripping off the whole of the cuticle 
and counting the setal rings. 
Prostomium ? 
Dorsal pores begin from furrow 12/13. 
The dorsal break in the setal rings is equal to about 2yz an- 
teriorly and 14yz behind the clitellum. The ventral break is 
practically absent,—not more than Itab. The setae of segments 
iv to ix are enlarged, especially those of v, vi and vii. Ventrally 
the setae are closer set than laterally and dorsally. The numbers 
counted were:—35/v, 42/ix, 40/xli, 46/xix, 46/xxvi. 
The clitellum extends over segments xiv—xvi=3. It is 
smooth, without visible setae or dorsal pores. 
The male apertures are situated in the setal ring of segment 
Xviii, on moderately large round dark-coloured papillae. They 
are in line with setae / of the adjoining segments, and ten setae 
intervene between the pores. 
There appears to be a single female pore in the setal ring of 
Xiv. 
The spermathecal apertures are four pairs, small, in grooves 
5/6—8/9; they are about the same distance apart as the male 
pores, and are in line with the setal interval fg. 
Internal Anatomy.—Septum 4/5 is somewhat thickened, 5/6, 
6/7 and 7/8 apparently considerably strengthened, 8/9 is thin and 
g/Io absent; 10/11—13/14 are all somewhat thickened. 
The gizzard, large and barrel-shaped, is in segment vill. The 
intestine begins in xv. Elongated diverticula originate in xxvii; 
tapering and showing a few constrictions, they reach forwards to 
XXIV. 
The last heart is in xiii. 
The micronephridia were mostly indistinguishable, but a 
dense fur was present on the inner side of the bodywall in seg- 
ments xv, xvi and part of xiv. 
Ovoid testis-sacs are present in segments x and xi, smaller in 
the former, larger in the latter. Those of the same segment appear
