Berkeley, Edith; Berkeley, Cyril. (1956). A new species and two new records of Polychaeta from Eastern Canada. Canadian Journal of Zoology. 34(4): 267-271.
Two of the three species recorded in this paper (Ceratonereis scotiae sp. n. and Nereis diversicolor O. F. Müller) were collected some years ago, but hitherto their occurrence has not been noted. The third (Tharyx marioni (Saint-Joseph)) was collected recently for the first time in Canadian waters.
