An account of the researches carried out on the algae living in the caves of Hungary is given. The results of the investigations concerning the algal flora of the Baradla, Peace, Abaliget, Pàlvòlgy, Kòlyuk caves are enumerated. Theories about the possible energy source utilized by these algae living in the complete darkness of caves such as radiation, symbiosis, chemosynthesis or auxothrophy are discussed. The question of the settling of algae into the caves is debated.
The Kolyuk cave lies in the southern part of Hungary in the Mecsek Mountains, about 3 km. in distance from the village of Mànfa. The material accepted for investigation originated from a recently discovered and until now completely entombed part of the cave. It was collected by the geologist Gàbor Magyari and consisted of material scraped from the walls and ceiling of a cavity in the cave, which could be reached only by underwater swimming. From these scrapings cultures were installed with sterile Knopp solution and after the algae present in the collection reproduced, a diversified flora developed which consisted of the following: Cyanophyta; 20 species, varietates and formae; Bacillariophyta; 2 species and varietas; Chlorophyta; 7 species. There was a total of 29 different taxa. Since the cave from which the collections were made was completely devoid of light, it is especially significant that a well developed blue-green algal flora was found. We thus have further evidence for our previously advanced theory (Claus, 1955, 1962 a, 1962b) that some algae were present in the caves at the time of their origin. They were able to survive in an actively assimilating vegetative state and not only in the form of cysts or arthrospores.

Arranged by geologist Dr. Temucin Aygen, the International Conference of Speleology and Karstology at Istanbul, with the participation of about twenty foreign scholars, opened first at Beyazit de Stamboul University. For three days papers and discussions enlivened the sessions, broken by tours around the Bosporus. During the following two weeks the members of the Conference took a field trip across Anatolia, through Ankara, Konya, Mersin, Antalya, Burdur, Izmir, Bursa, and Istanbul. They thus had the opportunity to investigate the principal karstic phenomena of Turkey; the Konya obrouks, travertines of' Yerkòpru and Antalya, caves of the Mersin region, vauclusian springs of Irviz and Manavgat, and so forth. The interest of these occurrences of Anatolian karst is unquestionable; in addition to the scientific problems they pose, they represent a great economic value either as tourist centres or as producers of electric energy and sources of water for irrigation.

The new subspecies Stenasellus skopljensis thermalis, from Banja Luka (Bosnie, Yugoslavia) is described. From the ecological point of view this form differs from the others because it inhabits underground waters of elevated temperature (240°C). Another constantly abundant species, St. hungaricus thermalis Mestrov, also occurs in Yugoslavia under the same ecological conditions, in the warm springs of Podsused near Zagreb. This indicates that these underground waters at elevated temperature are not accidental but preferred habitats for these forms, and confirms once again that thermal waters of this type are the biotopes-refuges in which certain relic forms are retained.

[(1335/4), Ferdinand Raimund]
Ptomaphagus hirtus has been successfully kept in laboratory culture at 12.5°C with food in surplus at all times. Eggs hatched in 18.5 days. Three larval instars were present, which had a total larval life span of 42 days. The pupal stage lasted 32 days. Adult males and adult females had average life spans of 2.2 years and 1.6 years respectively. Maximum adult longevity was 4.2 years. Females reached reproductive maturity a month after eclosion, young and old females produced one egg every 3.5 and 3.8 days respectively, and were reproductively active for as long as 2.5 years. Compared to European cave catopid beetles, this is a primitive or unmodified life cycle.
