By counting spermatocyte and oocyte bivalents and mitotic metaphase chromosomes in cleaving eggs, we have determined both the haploid (n = 19) and the diploid numbers (2n = 38) respectively, for the species Teredo utriculus. An XY and XO sex-determin

SUMMARYDiploid number 2n = 40 and haploid number n = 20 for the slug Lehmannia melitensis have been determined. These chromosome values being considerably different from those reported for slugs belonging to other limacid genera support the notion th

Three different karyomorphs with 2n=46, 2n=44 and 2n=42 for Capros aper (L., 1758) (Zeiformes) collected from the Gulf of Lion, near Banyuls-sur-Mer, France, in July 1990 were determined. Karyomorphs were characterized by the same arm number [Fundame
