OLE. MISS G. SWEET ON THE SPERMIDUCAL 
reach the level of the gland, the lower part of which they traverse, 
entering the spermiducal duct just as it leaves the gland. 
5. M. arrenvatus * (Spencer). 
Testes and rosettes, two pairs in segments 10 and 11. 
Sperm-sacs in segments 9 (posteriorly) and 12 (anteriorly). 
Spermiducal glands are two tubular, slightly-coiled glands 
lying transversely in segments 18 and 19, each with a short 
straight muscular duct. The two vasa deferentia of each side 
remain separate, running up within the muscular wall of the 
spermiducal duct, and entering the duct as it leaves the gland. 
On each side, just behind the opening of the spermiducal duct, 
is a slightly muscular sac enclosing a long curved penial seta. 
As in M. intermedius, there is on the ventral surface internally, 
below the nerve-cord and between the two spermiducal glands, 
a great mass of unicellular glands, which may occupy one to 
three segments. 
6. M. austraris tT (McCoy). 
In this form, which has been so completely described by 
Prof. Spencer, there are two, or occasionally three, pairs of testes 
and two pairs of rosettes. 
The sperm-sacs are found in segments 11, 12, 13, and 14, on 
the posterior wall in each case. 
The spermiducal glands are very much coiled, tubular struc- 
tures in segment 18; the duct of each is much coiled above and 
straight as it passes through the body-wall, receiving as it does 
so the two vasa deferentia. 
7. M. roseus f (Spencer). 
Testes two pairs in segments 10 and 11 with rosettes. 
Sperm-sacs in segment 12 on the anterior wall. 
Spermidueal glands tubular and closely coiled, either confined 
to segment 18 or extending into the segments before and behind, 
1.e. 17 and 19 (cf. fig. 5). The duct of the gland has strongly 
muscular walls, and is slightly curved. The vasa deferentia on 
each side do not unite, although they lie close side by side, deep 
down in the body-wall. They enter the spermiducal duct about 
halfway along its length.
