The indications of Ruszkowski (Ruszkowski, 1934) of the finding of 

 this species on Chimaera nrionstrosa L. , which is also reproduced in the 

 resume of Sproston, is erroneous and related to another species as 

 Brinkmann (Brinkmann, 1952a) has indicated. 



to the last host is contained in the supplement to the resume of St. Remy 

 (St. Remy, 1898) where it is written that C. kroyeri is encountered on the 

 skin of Rhombus maximus in addition to Raja species. Our attempts to 

 find the bases for these data were not successful. Consequently, apparently 

 there is some mistake, if it isn't in the materials of St. Remy themselves. 

 The latter, as a matter of fact, is improbable. (It is unlikely that there 

 was a mistake in the writing or compiling of the material by St. Remy, 

 but the error occurred somewhere else, nobis. ) Therefore, this species 

 must be considered as being encountered only on the representatives of 

 one genus of skates. 



Squamodiscus belengeri Chauhan is described by the author 

 of the species from three species of fishes of two genera of different 

 orders, specifically: from Sciaena belengeri (Cuv. and Val. ), S. carutta 

 (Bloch. ) (Sciaenidae, Perciformes), Muraenesox talabonoldes Bleck. 

 (Muraenidae, Anguilliformes). The accuracy of these indications of the 

 finding of S. belengeri on the last host arouses doubt because it is possible 

 that here there was a nnistake in labeling or the worms came onto the gills 

 of Muraenesox talabonoides from a devoured Sciaena. (Similar cases were 

 discovered by us for a number of Dactylogyridae ). In any case, for the p. 228 



time being, one must consider only the Sciaena spp. as the characteristic 

 hosts of S. belengeri and until the substantiation of the data about Murae- 

 nesox, one should not take the latter into consideration. 



Six species of monogenetic trematodes are indicated on two 

 species of fishes related to different orders: Bilaterocotyle chirocentrosus 

 (Chauhan), Calicotyle affinis Scott, Dionchus remorae (MacCallum), 

 Microbothrium apiculatum Olsson, Urocleidus mimus Mueller, and 

 Squalonchocotyle mavori (Linton). 



Bilaterocotyle chirocentrosus was described by Chauhan 

 (Chauhan, 1945) from Sciaena belengeri (Cuv. and Val. ) (Sciaenidae, 

 Perciformes) and Chirocentrosus dorab Forsk. (Chirocentridae, Clupei- 

 formes). Seven specimens of worms were encountered on the first host 

 and on the second, only one. As we see we encounter for the first time 

 the data of the same researcher which arouse doubts in some degree. 

 Running ahead, we shall indicate that for the entire family of Protonnicro- 

 cotylidae, to which Bilaterocotyle is related, occurrence on the herring 

 types (Clupeiformes, nobis) is unknown, with the exception of one case, 

 which confirms our conviction that the finding of B. chirocentrosus on
