    Abstract

    In a previous note (Seshappa, 1970) the present author has described a specimen of Cynoglossus semifasciatus Day with the right eye on the ' blind ' side of the head, almost in the original unmetamorphosed symmetrical position, and the left eye in its normal adult position on the coloured side of the body ; this is apparently the first instance of this kind recorded for any flat-fish in the Indo-Pacific region. Two more such specimens with the eyes situated in positions similar to the above have been since discovered. Also a large number of instances of eye-abnormalities of various degrees have been noticed by the author so far in the routine collections of this species examined during the years 1965-69. As the position of the eye and its migration form a very important part of the metamorphosis in the flatfishes, these specimens have been examined in some detail and the present paper gives an account of the results of these studies together with a discussion of the probable significance of the various abnormalities noticed.
