Abstract / Notes

In the littoral zone extending from the Aleutian Islands to the s. end of Lower California there are
recognized 67 valid spp. of polyclads, 48 Acotylea and 19 Cotylea. A zonation of the species with respect to
latitude is evident. A tabulation of this point reveals 2 spp. confined to arctic waters; 3 extending from
Puget Sound northward; 1 known only from British Columbia; 7 limited to Puget Sound; 5 ranging from
California to Puget Sound; 3 common to California and Oregon but not known n. of Oregon; 18 limited to the
California coast; 9 limited to s. California; 7 common to s. California and the Gulf of California; 9 limited
to the Gulf of California; and 2 extending from California far southward. The systematic account includes:
