Abstract
The karyomorphology of Glossogobius giuris (Gobiidae) obtained from Lake Taal and some rivers of Cavite in Luzon
Island, Philippines was described. Metaphase chromosome analysis (colchicine-sodium citrate-Carnoy's fixation-
Giemsa staining procedures) of the hematopoitetic cells in the anterior kidneys revealed that the diploid chromosome
number was 2n=46 (46A). Fundamental Number (FN) is also 46, since all chromosomal morphology were acrocentrics
without any distinguishable heteromorphic pair of chromosomes in the metaphase spreads from both dry and wet
preparations. This study confirms previous reports on the chromosomal sets of G. giuris from India.
