Publisher's Synopsis
Excerpt from Report of the Canadian Arctic Expedition, 1913-18, Vol. 9: Annelids, Parasitic Worms, Protozoans, Etc.; Part An; Oligochaeta; Lumbriculidae; Enchytraeidae; Southern Party, 1913-16
Eight of the collections contained mature enchytraeids representing six species distributed among four genera. Immature specimens not permitting specific identification were also present. Serious difficulties encountered in connection with some of the material necessitated provisional identification of two species. These difficulties were mainly due to incomplete, original descrip tions of arctic Eurasian species made many vears ago when the Enchy traeidae were little known and before the taxonomic impo1tance of several anatomical features 11 as recognized. Since the original Eurasian specimens are not mail able, the desucriptions' and accompanying illustrations are the sole dependence, thus preventing positive identifications, at least m some cases. For this re ason. Brief anatomical descriptions of the representatives of each Species treated in this report have been included and it will be understood that they are based exclusively upon the characters of the Canadian specimens. Characteristics of immature specimens are listed only in case it is unlikely that they are juvenile individuals of a species already discussed.
