Memoirs: The Chromosomes of the Cymothoid Igopod Anilocra

H. G. CALLAN

Anilocra mediterranea has a diploid chromosome number of twelve, eight of the chromosomes having median, and four subterminal centromeres.

The localization of chiasmata is extreme and is of a previously undescribed type, combining the terminal and centric systems.

The centromeres stain differentially from the non-centric regions of the chromosomes; they are the only parts stained at anaphase of first meiosis, and at metaphase and anaphase of second meiosis.
