The data on Helix albescens Rossmassler, 1839 reproductive system are provided. The presence of
glands of the auxillary copulatory organ, that gathered in two tufts and one massive stylophore (dart-
sac) are noted. The diverticulum in Crimean specimens is shown to be permanently absent, and the
flagellum is 1/2–2/3 times as long as penis. The penis has two papillae and the distinct pennial knob.
These characters can be used for identification of H. albescens.

Introduction
Peculiarities of the Helicidae reproductive system and the parts of it such as flagellum, diverticulum of
bursa copulatrix, epiphallus, female adnexa etc. are very important in species identification. On the other
hand, its are very closely linked with the peculiarities of reproduction, and ensure reproductive isolation,
reflecting, thus, much evolutionary important traits of species organization. Investigating the Helix albescens
Rossmassler, 1839 reproductive system we have found that our data are appreciably differ from information
presented in A. A. Shileyko’s (1978) monograph and in S. G. Damyanov and I. M. Likharev review (1979).
So it necessitate us investigate and examine this question.
Material and methods
We investigate the H. albescens reproductive system on materials from the different regions of Crimea
to allow for geographical variability. Altogether we examine 43 specimens from: Simferopol (14), Bakhchi-
saray (8), Kerch (5), Yalta (5), Pribreznoe (5), Sevastopol (2), Gvardeyskoe (2), Tarkhankut (2). Cuttings
were made by the standard methods (Likharev, Rammelmeyer, 1952; Akramovsky, 1976; Shileyko, 1978).
Results and discussion
H. albescens reproductive system presented in figure 1. All reproductive organs are
situated compactly, and tightened by the bands of connective tissue. Spermoviduct
include female part (oviductal gland) (fig. 1: 9) and prostatic gland (fig. 1: 10), which
surround allospermiduct. Further spermoviduct subdivided into the narrow vas deferens
(fig. 1: 11), that opens to the epiphallus (fig. 1: 13); and the distinctly curved free

oviduct (fig. 1: 5), that go further into the upper part of the vagina (fig. 1: 4) — between
the place of pedunculus of bursa copulatrix beginnings, and female part adnexa. The
pedunculus of bursa copulatrix (fig. 1: 6) in H. albescens are not distinctly curved. Free
oviduct (fig. 1: 5) and vagina (fig. 1: 1, 4) have a thick muscular walls.
To the female adnexa belongs: the glands of the auxillary copulatory organ (fig. 1:
3), that gathered in two tufts and temperately branch out, general number of the final
branches in each tuft are 8–15; and the dart-sac (fig. 1: 2). The section that is situat-
ed beneath the auxillary copulatory organ is the lower part of vagina (fig. 1: 1). It opens
to the atrium (fig. 1: 16). The vas deferens (fig. 1: 11) is the narrow duct, that is sur-
rounded with the circular muscular fibres, that contribute to the movements of the sem-
inal fluids and expulsion of it (Runham, 1988). The spermoviduct tightened to the penis
(fig. 1: 15) by the bands of connective tissue. The epiphallus of H. albescens is short

and very thin (fig. 1: 15), it’s ultrastructure is similar to the one of the vas deferens,
but it have a larger lumen and more developed musculature. Flagellum (fig. 1: 15) is
relatively short too, bulged at the basis; it’s length amount to 1/2–2/3 of the penis’
length. The penis is the tube of the thick circular musculature with outer longitudial
muscular fibres (fig. 1: 15). There are two penis’ papillas (fig. 1: 17, 18). Also we have
found the distinct pennial knob (fig. 1: 19).
The sperm of the reproductive partner arrive to bursa copulatrix (fig. 1: 7) through
the pedunculus (fig. 1: 6). A. A. Shileyko (1978) had show, that there is correlation
between flagellum’s and diverticulum’s lengths, namely the longer flagellum the longer
diverticulum.
H. Lind had (1973) demonstrate on H. pomatia that spermatophore body is devel-
oped in the epiphallus, and it’s tail end — in the flagellum. So, the smaller are the ones
the smaller is spermatophore. As the long spermatophore arrive, it’s fore-part penetrate
into the diverticulum, and the tail end is turned up to the bursa copulatrix. There is no
necessity of diverticulum in the species in which the spermatophore is bring up into the
partner’s genital tracts in the form of the compact clot, so the diverticulum is reduce
in that case (Shileyko, 1978). We do not find any considerable difference in H. albes-
cens reproductive system from different Crimea regions. Always are present relatively
very short flagellum, short epiphallus and always is absent diverticulum. It is contrary
to A. A. Shileyko’s (1978) data. He had gave the picture of H. albescens reproductive
system from Bulgaria, and had indicate in text that the length of the flagellum, in the
Crimean specimens, is amount to combined lengths of the penis and epiphallus; and
also had note the presence of well-developed diverticulum. By the other hand,
I. M. Likharev and E. S. Rammelmeyer (1952) had indicate, that H. vulgaris (= H. al-
bescens) have no diverticulum, and the one’s flagellum is short (“shorter than the penis
or equal to this one”, p. 490). In the N. N. Akramovsky’s (1976) review of the
Armenian molluscs author gave the description and picture of the H. albescens repro-
ductive system. He put this species to the other genus — Physospira C. Boettger, 1919
(p. 231, figure 114) because of the absence of diverticulum (and exactly this trait is the
base, in the author opinion, for the separation of the genus). N. N. Akramovsky shows
also, that length of the flagellum is equal approximately 2/3 of the penis’ length. It is
coincide with our data. We suppose that separation of H. albescens in the other genus
on the base of diverticulum absence is not well founded, because the typical species of
the genus, H. pomatia Linnaeus, 1758, can have a very short, rudimentary diverticu-
lum, and, rather can be without it (our data). As well A. A. Shileyko (1978) and
I. M. Likharev, E. S. Rammelmeyer (1952) show the possible rudimentary of the diver-
ticulum or the absence of it in H. pomatia. Besides the question about the presence or
absence of the differences in reproductive system structure of H. albescens from the
South of the European part of the former USSR and Caucasus at the one side and from
Bulgaria at the other calls for further investigations.
