SPOLIA ZEYLANICA. 
In most cases there is a pair of small transversely oval, rather 
flat, copulatory papillae at the anterior part of the eighteenth segment 
in the lines of the ventral pairs of setae, i.e., somewhat medial from 
the lines of the male pores. In one case there was an unpaired 
median ventral papilla instead of this pair. A pair of more circular 
copulatory papillae may also be detected sometimes at the nineteenth 
segment in front of the ventral pairs of setae ; and in one specimen 
two pairs of such papillae at the ninth and tenth segments in the 
corresponding situation.

body of Megascolex willeyi, from the ventral side. 
st marks the position of the spermathecal pores. 
The female pores lie medial from the setae a of the fourteenth 
segment; they may be paired or unpaired; in the latter case 
median. 
Two pairs of spermathecal pores occur in the intersegmental 
furrows VII./VIII. and VIII./IX. in the lines of setae b. 
Internal Anatomy.—The septa in the region of the anterior male 
organs are somewhat thickened. No septum is wanting in the 
region of the gizzard. 
Alimentary Tract.—A large gizzard is apparently lying in the 
sixth segment, but perhaps it may be in the fifth segment. No 
calciferous glands could be discovered in connection with the 
oesophagus.
