Abstract

^Selected morphometricaaii meristic characters Have been analysed in live common species of Cynoglossus at Calicut, namely, C. macrostomus Norman,.'C. dubius Day, C puncticeps (^chardson), C. M/nea/«s (Lacepede) and C lida (Sleeker). For comparing the morphometrrc ratios Pearson's coeflScient pf variation (P.C.), is used as a measure of the degree Pf >%riability. The total length/body length ratios >^ere found to be the least variable while the ratios connected with the eye and orbit showed the most variable P.C. in all the species. A comparative table and description are given of the ratios studied of the different characters for the five species chosen. The calculated values of t for the mean ratibs in all paired combinations of the five species have been tabulated, and the Probability (P) is found to be significant for most of the comparisons made.
