Micrometrus minimus was uniquely distributed. It was abun- dant in shallow water where it was also the nu- merically dominant surfperch, and its abundance decreased dramatically with increasing depth. Embiotoca jacksoni was also uniquely distributed. It was most abundant at middle depths and de- clined in both shallower and deeper water. At m, E. jacksoni was the numerically dominant surf- perch. The distributions of H. caiyi and R. vacca were very similar to each other, maximum num- bers occurring in deeper water, m to m. Phanerodon furcatus was distributed similarly, with its maximum numbers in deeper water. The overall abundance of this species, however, was considerably lower than either those of R. vacca or H. caryi. Chi-square tests for homogeneity of the adults indicate that both A/, nuniimis and E. jacksoni were significantly different from each of the other species. No differences of statistical significance are found among H. caryi, R. vacca, and P. furcatus. Subadult distributions were noticeably different from adult distributions. Subadults of each species were not greatly different in distribution from each other and were more evenly distributed at all depths than the adults. Embiotoca jacksoni sub- adults showed some decrease in abundance with increasing depth. Rhacochilus vacca was very evenly distributed. Hypsurus caryi and P. furcatus subadults were distributed most like t
