Abstract
Nine spp. of birds (49 speci-mens) and 14 spp. of mammals (122 specimens), collected from Amherst, Massachusetts, and vicinity, were examined for worm parasites. 40 spp. of helminths were obtained: 17 nematodes, 13 cestodes, 8 trematodes, and 2 acantho-cephalans. None are new to science. Most of the distribution records are new. Many of the parasites may be important economically as seen by actual damage to surrounding tissues. This is particularly true of Alaria intermedia, Schizotaenia americana, Crenosoma vulpis, Crenosoma zederi, and Trichinella spiralis.
