and the conducting tissue of the bursa described by Brumpt. 
Of the spermatophore glands, those described by Brumpt as 
A and B glands are present, while I am doubtful as to the 
presence of C glands. The glands A are well developed, and 
are enclosed in the muscular tunic of the terminal parts of 
the ejaculatory canals. The glands B, and perhaps C, surround 
the terminal parts of the ejaculatory canals and open into the 
•common part. Here the resemblance, owing to the develop- 
ment of the A glands, is more to the Glossiphonid type than 
to C. lopliii. 
In the female organs, owing to the isolated ovaries and 
the absence of both copulatory area and conducting tissue, 
Austrobdella resembles Callobdella lubrica, Platy- 
bdella solese, and Glossiphonia complanata. 
Concerning the interesting fertilisation by means of hypo- 
dermic injection of spermatophores, which Brumpt has shown 
to be true in most marine leeches, I have not yet ascertained 
if a similar phenomenon occurs in Austrobdella. I hope 
later again to keep these leeches in captivity and to endeavour 
to bring about copulation with a view to determining this 
point. 
There are five pairs of testes (PI, 1, fig. 1, T., Text-fig. 6, T .) 
placed in somites 14-18 inclusive. The vasa deferentia 
(PI. 2, fig. 12a, V. def.) on leaving the connective-tissue, 
become more than doubled in their diameter and constitute 
the ejaculatory canals, which lie in the expanded anterior 
end of the ventral lacuna. These ejaculatory canals become 
considerably coiled at the level of the 12tli nerve ganglion 
(PI. 2, fig. 12a, Ej. c .), and the lumen of each increases 
slightly and forms a seminal vesicle. They then come into 
close relation with the dorsal blood-vessel (PI. 2, fig. 12, 
Ej.c .) and shortly open dorso-laterally into the terminal parts 
of either side (PI. 2, fig. 12a, Ej. t.). The terminal parts of 
the ejaculatory canals are provided with a muscular tunic 
(PI. 2, fig. 12, Ej. t.) which encloses the unicellular glands, 
•called the A glands by Brumpt (1900). The two terminal 
parts open into a common part, the spermatophore sac of
