Abstract
The chromosomes of the pleuronectiformfishes have been reported in 23 species fromfive families within eight families(Nogusa, 1960; Ohno and Atkin, 1966; Ivanov, 1969;Fukuoka and Niiyama, 1970; Barker, 1972;LeGrande, 1975).In the present paper, thekaryotypes of a paralichthyid, Paralichthvsolivaceus, and two cynoglossids, Paraplagusiajaponica and Cynoglossus interruptus are describedand compared with other members ofthis order.P.olivaceus has been karyotypedby Nogusa(1960)using the gonad sectionmethod, and the other species represent thesecond and third records on the karyotypesin the family Cynoglossidae respectively.
