Taxonomic Composition of the Family Centropyxidae (Testacealobosia, Rhizopoda)
Dekhtjar M. N. — Modification of apertual invagination forming various internal
shell structures observed in testate amoebae of the family Centropyxidae are discussed.
Internal structures of three types are distinguished and treated as generic characters.
The genus Armipyxis gen. n. is established (type species Centropyxis discoides
Penard, 1902), to include A. discoides (Penard, 1902) comb. n.), A. mirabilis
(Bartos6, 1940) comb. n. (=Centropyxis mirabilis Bartos6, 1940) and A. gasparella
(Chardez, Beyens, 1988) comb. n. (=Centropyxis gasparella Chardez, Beyens, 1988).
Composition of the genus Centropyxis is partially reconsidered, two species are
transferred into the genus Paracentropyxis Bonnet, 1961: P. sylvatica (Deflandre,
1929) comb. n. (=Centropyxis sylvatica Deflandre, 1929) and P. matthesi (Rauenbusch,

Peculiarity of Ultrastructure and 45Ca Methabolism
of Osteoclasts in Conditions of Hind Limb Unloading and Microgravity. Rodionova
N. V., Oganov V. S. — Using methods of electron microscopy, morphometry and
cytochemistry the peculiarities of ultrastructure of osteoclasts and resorptive
processes of the mineralized matrix in spongy bone of the rat femoral bone metaphyses
following the experimental hind limb unloading model (28 days), as well as in
rats exposed on American Space Station SLS–2 (2 weeks) were studied. The methods
of light and electron microscopy radioautography 45Ca were used in the experiment
of hind limbs unloading. The results of investigations demonstrated that in zones
of adaptive remodeling the resorption and destruction processes in the bone tissue
increase under the supportive unloading. It takes place by increasing of functional
activity of osteoclasts (in microgravity conditions we registered the «giant»
osteoclasts). The dynamics of 45Ca –incorporation into osteoclasts is an indicator
of a direct involvement of cells in calcium transfer from the resorpting mineralized
matrix to intercellular environment and intensification of this process at hind
limb unloading model.
Key words: osteoclasts, resorption, electron microscopy radioautography, hind
limb unloading model, microgravity.

Formation of Parachordals, Acrochordal Cartilage
and Trabecula Cranii in the Skull of the Sand Lizard, Lacerta agilis (Reptilia,
Squamata). Yarygin A. N. — Formation of chondrocranium of Lacerta agilis Linnaeus,
1758 in early embryogenesis is described. Particular attention is given to both
the primary anlagen of the neurocranium, and participation of the acrochordal
cartilage in formation of the crista sellaris. The attention is paid to debatable
questions. Morphological descriptions are based on hematoxylin and counterstained
with eosin serially-sectioned embryos. The results show that mesenchymatous rudiments
of parachordals, acrochordal cartilage and trabecula cranii are the first to appear
in the chondrocranium of Lacerta agilis. The parachordals are the first to chondrify
following by chondrification of the acrochordal cartilage and the trabecula cranii.
Key words: skull development, Reptilia, parachordals, acrochordal cartilage, trabecula
cranii.

Nesting Biology of the Wasp Katamenes flavigularis
(Hymenoptera, Vespidae) in Crimea. Fateryga A. V., Ivanov S. P. — The nests
of Katamenes flavigularis, Blu#thgen, 1951 were placed in concavities of stones
and contained from 1 to 9 cells. The cells were dome-shaped and placed in the
same plane; they joined to each other and had the common lateral walls. The cells
were built by females with using pebbles attached to substrate and with each other
by clay soil mastic. The collar of the cell was made only from mastic. After the
cell had been completed and sealed it was covered by female with additional layer
of mastic. As all cells had been built the nest was covered by additional layer
of pebbles and mastic. The outer layer of the general nest cover was made from
pure mastic. An egg was attached to the rear cell wall by a filament after the
cell had been completed and before provisioning. Females were hunting for the
blue caterpillars (Lepidoptera, Lycaenidae). They stored from 6 to 11 caterpillars
in each cell. Flies Amobia signata (Diptera, Sarcophagidae) and gold-wasps Stilbum
calens, Chrysis (Tetrachrysis) sp. and one unidentified species (Hymenoptera,
Chrysididae) were recorded as inquilines. Leucospis gigas Fabricius (Hymenoptera,
Leucospidae) was registered as the parasitoid. The general posterity mortality
averaged 38.2%.
Key words: Katamenes flavigularis, nest construction, foodstuffs composition,
nest-building and hunting activity, parasites.

Peculiarities of Burchelly zebras (Perissodactyla,
Equidae) Reproduction under the Semi-Free Conditions in the Southern Ukraine.
Steklenev E. P. — The Burchelly zebra, Equus burchelli, Gray, 1824 is well
acclimatized under semi-free conditions in Southern Ukraine, effectively reproduces
and grows its offspring. Its reproduction has a seasonal character, conditioned
mainly by a long term of winter housing and is characterized with spring — summer
sexual activity and foaling period. The successful passage of sexual processes,
activisation of gametogenesis, biological value of gamets, conception rate of
germs and embryonic development of fetuses promotes the favourable grass stand
in the spring — summer period. Sexual activity of the Burchelly zebras in confirmed
by the data of morphological and physiological character of gonads in various
seasons of the year.
Key words: zebra, reproduction, ovaries, seasonality, testes, spermatogenesis,
sexual activity.

The First Finding of Freshwater Sponges Eunapius
carteri (Porifera, Spongillidae), beyong its Common Range of Distribution, in
Cooling Reservoir of Khmelnitska NPP. Trylis V. V., Babaryga S. P,, Protasov A.
A..— Rare for Ukraine species of the freshwater sponge Eunapius carteri (Bowerbank,
1863) (Porifera, Spongillidae) was found in cooling reservoir of Khmelnitska NPP.

is a northern boundary of distribution of this species, so finding of its population
more northwards possible caused by abnormal temperature mode of reservoir.
