NOV. A sample of 61 larvae of this small species from Site 12a was fixed for IIS-3 ( Fig. 8A ) and IIL-1 ( Fig. 9 ) of Basrur (1959) . The sex chromosomes were undifferentiated and only one rare polymorphism, a heteroband in section 11, was detected ( Table 7 ). Larvae, especially when mature (i.e. with dark gill histoblasts), typically had at least several nuclei with ectopic pairing of the telomeres of any two to four of the six arms.
