This thesis is a report of the findings of two years of part-time work on the limpets of the family Acmaedae. The major portion of the work was done on the Monterey Peninsula between Point Pines, 36° 38' 30" N. latitude, 121° 56' 00" W. longitude, and Pescadero Point 30° 33' 40" N. latitude, 121° 56' 30" W. longitude. The work on homing in Acmaea persona, artificial parthenogenesis in the eggs of Acmaea pelta, and artifical insemination of the eggs of Acmaea pelta was carried on at the Pacific Marine Station, Dillon Beach, California at 38° 14' 30" N. latitude, 122&176; 58' 30" W. longitude during the summer of 1947.
