✦ Synopsis


Differences in karyotypic structure are compared with reported isozyme differences in three Mediterranean species of Patella. In addition, the karyotypic structure of Patella is discussed in terms of the karyotypic variability of Archaeogastropoda. Both P. lusitanica and R caerulea have a haploid complement of n = 9 (6 metacentric, 1 submetacentric, 1 subtelocentric, 1 telocentric chromosome in P. lusitanica and 6 metacentric, 1 submetacentric, 2 telocentric chromosome in P. caerulea). P. aspera, although regarded as morphologically more closely related to P. eaerulea, has a haploid complement of only n = 8 (7 metacentric and 1 submetacentric chromosomes),

## Abstract There are twenty‐seven spermatogonial chromosomes in Tenoder'a sinensis, three of which are larger than the others and lag behind in anaphase. These three chromosomes have been traced through the prophases of the first spermatocyte to the metaphase, where they appear as a hexad. In the

The karyotypes of four species of Dyscophinae and eight species of Cophylinae were analyzed. The chromosome number was 2n = 26 in all cases. Between the two subfamilies a difference in the form of the karyotype was observed; the chromosomes show a gradual decrease in length in the Dyscophinae, where
