Thirty-eight of the counties and districts have never had any earthworms re- ported previously. At present, there are insufficient megadrile data available to utilize fully some of the habitat information. For example, it would be unwise to try to correlate in detail megadrile distribution with the distribution of soil types until addi- tional surveys from other parts of the continent are completed (cf. Jordan et al., 1976). A preliminary examination of megadrile-ve

Gates, 1972a). many of the records of Ap. longa may have been attributed to other species such as Lumbricus terrestris or Allolobophora terrestris and various forms of varieties. There are a few reports of limited collections of this species in North America (cf. Eaton. 1942; Gates, 1953a; Murchie, 1956; Reynolds, 1973c, 1975a-c. 1976a. c; and Reynolds et al., 1974).
