ELLOBIOPSIDAE 287 



Marshall, Nicholls and Orr (1934). Note on the occurrence of E. chattoni on Calamis finmarchicus 

 in Loch Striven (Firth of Clyde area). 



Fage (1936). New generic name Amallocystis for Staphylocystis, preoccupied. Description of 

 Amallocystis fasciatiis, a parasite on the ventral side of the first abdominal segment of Gnathophausia 

 zoea Will. S. (Mysidacea) from the Dana Expedition (off the Fiji Islands and off New Zealand, 3000 

 and 2500 m. wire respectively). Fage describes the characters separating the species from Amallocystis 

 racemosiis (Coutiere), gives an account of the organ of fixation, and notes on cytology, and refers to the 

 influence of the parasite on the host. One of the hosts, a male, does not appear to have undergone any 

 change as a result of being infested by the parasite. On the contrary the other host, a female, shows 

 a pronounced retardation in the development of the sexual characters. The oostegites of the parasitized 

 female are considerably smaller than those of uninfested females of the same size, and the mass of 

 hairs found on the sternal plates of normal females has remained very much under-developed in the 

 specimen bearing the parasite. 



Jepps (1937). Notes on young and aduh stages of Ellobiopsis chattoni attached to the mouthparts 

 and the second antenna of Calamis helgolandicus Glaus from the Clyde Sea area, and on very young 

 stages of the parasite attached to the setae of the appendages. The larger specimens showed well- 

 developed roots penetrating into the appendages of the copepod. In some of the gonomeres the 

 formation of buds leading to sporulation was observed. A plug and an anterior cone are described as 

 often occurring on the top of the gonomere; these might be the remnants of a previous gonomere, 

 detached from the trophomere before the present gonomere developed. 



Fage (1938). Description of Amallocystis capillosus, a parasite of Pasiphaea tarda Kroyer from the 

 Skagerrak. The external parts of the parasite form two tufts of long-stalked trophomeres, each tuft on 

 one side of the base of the rostrum. The basal part of each tuft passes through a hole in the cuticle 

 into the internal part of the parasite, forming the organ of fixation, which extends transversely under the 

 rostrum of the host. This internal part has a rough surface. Fage remarks that the simple Ellobiopsidae, 

 which may be found in various parts of their hosts, in all probability attain their full development on 

 the spot where the spore originally attached itself. For the compound Ellobiopsidae, each species of 

 which occurs in a definitely localized part of its host, it is hardly possible to believe that they originally 

 fixed themselves on the spot. In connexion with this Fage points to the probability that m the life 

 history of these parasites there occurs an internal stage. 



Coutiere (1938, 1940 «, 6). Reprinted previous papers by the same author (Coutiere, igiia-c). 

 Fage (1941). Data from a previous paper (Fage, 1936) with additional notes. Amallocystis fasciatus 

 on a third specimen of Gnathophausia zoea (from off Guyana), and on two specimens of G. itigens 

 (Dohrn), one from the Indian Ocean, the other from the Atlantic. 



Fage (1942). Notes on the effect of the parasite Amallocystis fasciatus on its hosts. 

 Einarsson (1945). Remarks on Amallocystis sp., a parasite of the Euphausiids Thysanoessa inermis 

 (Kroyer) and Th. raschii ( M. Sars) from Icelandic waters. The parasite occurs on the carapace of the 

 host, as a rule in the region of the genital gland, and in some cases in the region of the stomach. Often 

 more than one parasite on one host. Description of the root system extending from the organ of 

 fixation into the ovary of the host. The parasite seems to castrate the animals which it infests, as 

 external sexual characters are totally absent and the ovary is completely disorganized in the specimens 

 bearing the parasites. 



Boschma (1948). Description of Amallocystis fagei, a parasite of Euphausia vallentini Stebbing and 

 other Euphausiids not mentioned by name (material from various Discovery Stations in the Antarctic), 

 with an account of the sieve plate occurring in the organ of fixation.
