“…At McMurdo Sound, Holloway and Bier (1967) Cysticanths of C. hamanni have been recorded from antarctic fishes of 12 species representing four families (Nototheniidae, Bathydraconidae, Zoarcidae, and Chaenichthyidae) (Baylis, 1929 ;Holloway and Bier, 1967 ;Markowski, 1971 ;Zdzitowiecki, 1978b ;Holloway and Spence, 1980 ;and others Holloway and Bier (1967) were unsuccessful in attempts to establish experimental infections of C. hamanni in amphipods of the genus Orchomonella Sars (= Orchomene Boek), family Lysianassidae, at McMurdo Sound.…”

“…Corynosoma hamanni is a typical parasite of Weddell seals, Leptonychotes weddelli Lesson, Ross seals, Ommatophoca rossi Gray, leopard seals, Hydrurga leptonyx de Blainville, and crabeater seals, Lobodon carcinophaga Hombron and Jacquinot in the Antarctic (Leiper and Atkinson, 1915 ;Edmonds, 1957 ;Holloway and Bier, 1967 ;Golvan, 1959 ;and others). Several other species, morphologically similar to C. hamanni, have been described from marine mammals in the Antarctic and Subantarctic.…”

“…Acanthocephalans of the genus Corynosoma are typical parasites of pinnipeds inhabiting the subantarctic and antarctic seas (Deliamure, 1955 ;Golvan, 1959 ;Holloway and Bier, 1967 ; and others) but occur only incidentally (with the exception of C. shackletoni and C. clavatum Goss, 1941) in avian final hosts (Goss, 1941 ;Johnston and Edmonds, 1953 ;Edmonds 1955 ;Jones and Williams, 1969 ;Williams et al, 1974 ;Zdzitowiecki, 1978aZdzitowiecki, , 1978b. Generally, specimens of C. hamanni, C. singularis, and C. bullosum were not sexually mature or gravid when they occurred in seabirds and development usually did not proceed beyond that observed in cysti canths from fish.…”

SUMMARY. Four species of acanthocephalans are reported from seabirds, nototheniid fishes and gammaridean amphipods in the western Antarctic. Corynosoma hamanni (von Linstow, 1892) was found in Phalacrocorax atriceps King, Chionis alba (Gmelin), Larus dominicanus Lichtenstein, and Catharacta lonnbergi (Mathews). The complete life cycle of this acanthocephalan was elucidated : cysticanths develop in the haemocoel of a gammaridean amphipod, Pontogeneiella sp. of the family Eusiridae and presumably, following ingestion of parasitized amphipods, encyst in the body cavity of antarctic fishes of several species. Corynosoma singularis Skriabin and Nikol'skii, 1971 was found only in P. atriceps. Corynosoma bullosum (von Linstow, 1892) occurred in both P. atri ceps and Pygoscelis papua (Forster). Neither of these species of Corynosoma had previously been reported from avian hosts. Corynosoma shackletoni Zdzitowiecki, 1978 was recorded only as a parasite of P. papua. The first known gravid females of this species were found during this study, indicating that C. shackletoni is a typical parasite of avian, rather than mammalian, final hosts. It is the first acanthocephalan known to typically occur in an avian definitive host in Antarctica. The host-distribution of Corynosoma spp. in birds suggested that these parasites were being acquired from piscine or possibly amphipod prey, generally in nearshore situations. Seabirds representing the zooplanktivore feeding guild were not infected. This indicates that pelagic foodwebs, and other trophic pathways in which Euphausia superba Dana is a dominant prey organism, are probably not involved in the life cycles of Corynosoma spp. The host and geographic distribu tions of Corynosoma in piscine, avian, and mammalian hosts suggested that oceanographic factors, particularly the Antartic Convergence, could limit the ranges for some species of parasites. Hostparasite coevolution appears to have had an important influence on the species composition of the acanthocephalan fauna of seabirds and marine mammals in Antarctica.

A morphological study of the presoma of adult Corynosoma hamanni (Linstow, 1892) was undertaken in a n effort to clarify some problems encountered during analysis of a large collection of juveniles of this species assembled from fishes of McMurdo Sound. This study is based on approximately 600 adult specimens recovered from four Weddell seals, Leptonychotes weddelli, collected at McMurdo Sound.Morphologically the proboscis armature is more varied than previously reported and consists of 18 to 23 longitudinal rows each with 11 to 15 hooks of two distinct types. At the apex of the proboscis is an undivided, bi-nucleated apical organ unlike that described for species of Neoechinorhynchus. In the basal third of the proboscis is a thin-walled vesicle which extends into the anterior quarter of the proboscis receptacle. The more posterior of two external folds on the presoma is a cuticular invagination permitting recognition of the neck-trunk border of C. hamanni. Lemnisci originate between the two folds and extend into the trunk cavity between the body wall and extensive neck retractor muscles. Contrary to Linstow's original description, each lemniscus is a single structure.Several limitations in material prevent speculation at this time about the limits of intraspecific variation in C. hamanni.
