1400 MHz polarimetric profile observations, made with the Arecibo instrument, are reported for a group of 56 weaker pulsars (including three interpulsars). These results are combined with previously reported 21 cm polarimetry on 11 stronger pulsars. Each pulsar is discussed in terms of the classification system published by Rankin in 1983 and 1986 in order to explore the strengths and weaknesses of the scheme. All but two of the 64 pulsars were classifiable into one of six groups. These six species fall into two broad categories, one in which a core component was evident and another wherein no core emission was apparent. Of the 64 pulsars, 44 (69 percent) were identified with the three core-associated classes and 18 (28 percent) with the three conal species. Full period polarimetric measurements are also given for three interpulsars, and classifications are attempted for both their main pulse and interpulse profiles. 39 refs.
