HELIX (MAOULARIA) PUNCTATA.

contain a spermatophore. It lies to the left of the stomach. 
Its duct—or spermatlieca—crosses over the female portion of 
the common generative canal, becomes intimately related 
with it for some portion of its course, and then leaves it, 
recrosses over the female portion of the common generative 
canal, and courses down its left side, lying in relation with 
the oesophagus, to join the oviduct in the formation of the 
vagina. As in Helix cispersa and others of this genus, there 
is a diverticulum given off from the duct; but in this speci¬ 
men there was no indication of a globular head ; it ran in 
company with the common generative canal, and ended 
blindly near the albuminiparous gland. The digitate glands 
are biramose, and arranged in two sets; the dorsal set 
opening into the dorsum of the vagina posterior to the 
opening of the dart-sac, the ventral set opening into the 
vagina on its ventral aspect directly opposite the opening of 
the dorsal set. In each set there are six tufts. The 
dart-sac lies on the right side of the body, and is separated 
from the buccal mass by the dorsal set of the digitate glands 
and the flagellum; it is of an elongated pyriform shape, and, 
comparatively speaking, small. In this specimen, though 
captured in the spring of the Argentine Republic, there was 
no spiculum amoris present. The flagellum is exceedingly 
short (2 cm. in length) and correspondingly stout; it 
possesses a special retractor muscle similar to what Ashford 
has described as obtaining in Testacella haliotidea; it lies on 
the right side of the buccal mass and the penis, and is coiled 
once upon itself in the dorsal set of the digitate glands. The 
penis is long, rounded, and cylindrical; it lies on the right 
side of the buccal mass at its anterior extremity and ventral 
to the retractor muscle of the right tentacle; its hinder end 
curves over the posterior portion of the buccal mass, lying 
partly on it and partly on the oesophagus, and separated in 
this position from the dart-sac by the digitate glands and 
flagellum. Its retractor muscle is long, and passes over the 
oesophagus to unite with the left lateral walls of the prostoma. 
In comparison with the reproductive apparatus of our 
English Helices it is worthy of note that in this species 
there exists no naked-eye indication of that fluffy mass 
around the male portion of the common generative canal 
which is generally known as the prostate ; that there is 
present a special musculus retractor flagelli, and a diverti¬ 
culum from the spermatlieca which may be regarded as a 
secondary spermatlieca. The short and correspondingly 
stout flagellum which is coiled only once upon itself, and the 
relation of the albuminiparous gland to the stomach, are also 
worthy of note.
