Abstract / Notes
M. hustedi, from Duxbury Bay, Mass., is described on the bases of pigmentation, ciliation, size, chromosome number and morphology. The chromosome complement shows in several ways evidence of polyploidy. There are in this sp. 12 chromosomes (somatic), twice or 3 times the number described for other spp. in the genus. No other Macrostomum yet described has 12 chromosomes. Irregular numbers are found in meiotic 2d metaphases; multivalent associations at the 1st meiotic prophases are common. The type of polyploidy is, however, not clear. Polyploidy in other animals is considered in the light of this report.
