The elephant fishes are Holocephali of the family Callorhynchidae, 

 genus Callorhynchus. The Chimaeridae is a related family. The Holo- 

 cephali in widely separated parts of the world tend to have distinctive, 

 related parasites. An aspidogastrid trematode, Macraspis elegans Olsson, 

 1869, known from Chimaera monstrosa in the North Atlantic, was re- 

 corded from Callorhynchus milii in New Zealand (Manter, 1954). 

 The cestodarian genus Gyrocotyle includes several species, all from 

 chimaeroid fishes. Four monogenetic trematodes are known from these 

 fishes: Calicotyle affinis Scott, 1911 ; C. kroyeri Diesing, 1850; Chimaeri- 

 cola leptogaster (Leuckart, 1830) Brinkmann, 1942, from Chimaera 

 monstrosa in the North Atlantic; and Callorhynchicola branchialis 

 Brinkmann, 1952, from Callorhynchus callorhynchus off the coast of 

 Chile (Latitude 41° S). These Monogenea are so unique that Brinkmann 

 (1952a, p. 96) has placed them in a new superfamily, Chimaericoloidea. 

 They are, to date, the only two species known in the family Chimaeri- 

 colidae Brinkmann, 1942.
