The paper presents new data on the distribution of Pelodytes caucasicus, Bufo verrucosissimus and Pelias tuniyevi in South Ossetia. The research was carried out on the Dzau district territory in the first decade of July 2023 and in the third decade of April 2024. In the Patsa River gorge (a right tributary of Bolshaya Liakhva River), P. caucasicus, B. verru-cosissimus, and P. tuniyevi were discovered for the first time, and P. caucasicus and B.

The results of our laboratory hybridization of green-bellied (Darevskia chlorogaster) and Caspian (Darevskia caspica) lizards are presented. When crossing D. chlorogaster females and D. caspica males, 7 hybrid individuals were obtained. The newborn lizards had body lengths of 24.59–27.11 mm and masses of 0.32–0.37 g. Incubation lasted 57–61 days. After the first period of hibernation (286–357 days after leaving the eggs) the hybrids had their first attempts at mating and laying eggs.

Abnormal activity of Pelophylax ridibundus in the cooling pond of the Balakovo NPS (Saratov region) was detected during the winter period of 2003. The temperature range within which this activity was observed corresponds to that for the exit of individuals of this species from wintering during the spring period.

A third specimen of Psammophis lineolatus (Brandt, 1836) from the Caucasus (near the Anabad village, Ordubad district, Nakhchivan Autonomous Republic of Azerbaijan) is described.

We describe a case of temporary transfer of a striated lizard, Lacerta strigata Eichwald, 1831 to eating winged individuals of the cornfield ant, Lasius alienus (Foerster, 1850) registered in the territory of the Staropavlovskaya village, Stavropol region.

The paper describes a first case of successful hunting of a Parasteatoda tepidariorum (C. L. Koch, 1841) spider for a juvenile individual of Pontic Lizard, Darevskia pontica (Lantz et Cyrén, 1919), recorded in the territory of Slavyansk-on-Kuban town (Krasnodar Region, Russia).

Data are given on the lizard specimens of the genus Bronchocela (the family Agamidae) of the Vietnam fauna, accumulated in the herpetological collection of the Zoological Museum of Moscow University. The following data are presented for each specimen: the accession number, the date and location of capture, the habitat, and the collector. The places of capture are shown on the map of the country. A new key for the Vietnamese species of Bronchocela is provided.

Data on the Acanthosaura lizards of the Vietnam fauna, deposited in the herpetological collection of the Zoological Museum of the Moscow University, are given. The following data are provided for every sample: accession number, capture location, habitat, and collector. The places of capture are shown on the map of the country.

A brief history of the formation of the batrachological collection of the Zoological Museum (Saratov State University) is given. The museum’s collections taken within the Saratov region and beyond are analyzed.

On the basis of modern field surveys, collection data, and analysis of the literature data, a list of amphibian and reptile species recommended for inclusion into the 3rd edition of the Red Book of the Saratov Region was compiled. It contains 7 species of the batrachofauna and herpetofauna of the region, belonging to 3 groups, 5 families, and 6 genera. We offer to add 1 new species into the Book and to exclude 1 species, and there appeared prerequisites for revision of the existing protection status of 2 taxa.
