Quite similar to cristatellus directly above. In details of karyotype, cristatellus and scriptus are very similar. There are six pairs of metacentric macrochromosomes and six autosomal pairs of small chromosomes, of which the largest three pairs are also metacentric. Males have three unpaired sex chromo- somes (Figs. 7c, d). The one exceptional animal was the A. c. wileyae from Vieques which had the extra body (presumed univalent) in meiosis (no mitotic divisions were seen in the specimen from Cayo Lobos that.
