tom 38

nr 4

Mounts of four digenean forms designated by Prudhoe and Bray 1973 only to the genera or family were re-examined. "Opecoelidae (sp. indet.)" = Neolebouria terranovaensis Zdzitowiecki, Pisano et Vacchi, 1993. "Helicometra sp." = Helicometra antarcticae Holloway et Bier, 1968. "Stenakron sp. indet." = Stenakron glacialis Zdzitowiecki, 1989. "Neolepidapedon sp." =Neolepidapedon macquariensis sp. n. Specimens of "Neolepidapedon sp." (= probably N. macquariensis sp. n.) collected from Notothenia mizops are accompanied on the slide with other digeneans, Postmonorchis variabilis Prudhoe et Bray, 1973.

nr 3

In total, 1446 Antarctic and subantarctic teleosts were examined for nematodes. One species, Ascarophis nototheniae Johnston et Mawson, 1945, is reported. New data on the biometrical variability and the occurrence or absence of this species are given. Three areas of the West Antarctic (the South Shetland Islands, South Georgia and South Orkneys) as well as three areas of the East Antarctic (Davis Sea, Weddell Sea and off Adelie Land) are new geographical localities for this nematode species. Also, 21 fish species represent new host records for A. nototheniae. Two predatory channichthyid species, Chaenocephalus aceratas and Cryodraco antarcticus are the most strongly infected fishes in all examined areas, except the Weddell Sea.
