A historical survey of nomenclature is presented for species described under the genera Maena, Smaris and Spicara, the last being the most recent. A morphological study and an electrophoretic study of the crystalline lens of the various species involved is described. The techniques and standards used are given. As a result of the study, and bearing in mind the effects of the variations mentioned above, it was concluded from electrophoretic comparisons that only 2 species are valid, Spicara maena and... |
