NOTES ON AUSTRALIAN EARTHWORMS, 
fairly long, with a single rudimentary pear-shaped cjecum close to 
the exit. 
Corresponding with the genital papillse are distinct internal 
white elevations, a pair in front of the genital ducts, the others 
median, underlying the nerve cord. No penial setse met with. 
Last pair of hearts in xiii. 
Nephridia : numerous minute tufts of tubules, more conspicuous 
in the anterior region as far back as about segment xvii ; no large 
specialised nephridia in the posterior region as in Megascolides. 
Hah. — Cullenbone, near Mudgee, N.S.W. ; from the flats, 
bordering the Cudgegong River (collected by Mr. A. G. Hamilton) 
This species is allied to C. saccarius, but is easily distinguish- 
able by (1) the presence of genital papillae on the last clitellar 
segment, the presence of which interferes with the completeness 
of the girdle on this segment, (2) the presence of four instead of 
five pairs of calcifei’ous pouches, (3) the caeca of the spermathecfe 
being distinctly pear-shaped not rosette-like knobs, (4) while 
intersegmental tumid areas such as are usually present on the 
ventral surface between some of the pre-clitellar segments in 
C. saccarius, are not represented in any of the specimens. 
Cryptodrilus canaliculatus, n.sp. 
Twelve spirit specimens (not well preserved and much extended) 
from 12-5-25 cm. long, 3-5-5 mm. broad; number of segments from 
about 250-265. 
Buccal ring bi-annulate superiorly, not divnded by the pro 
stomium, though being ribbed all round it sometimes appears as if 
it were completely or half divided by the prostomium. Body 
faintly but distinctly canaliculate throughout in the median dorsal 
line. 
Clitellum comprising four complete segments, xiv-xvii, com- 
plete all round, in addition the posterior annulus of xiil and 
the anterior one of xviii may be modified, but are not properly 
included.
