In shoaler water, however, in that general vicinity, the relationship is the reverse, as off Casco Bay in 30-40 meters, and at a neighboring station in about 90 meters, where P. propinquus greatly predominated over P. borealis TABLE II List of "various" fishes other than those recorded in Table I, trawled on bottom in Jeffrey's Bowl and in the open basin of the Gulf of Maine, during August, 1936.

(39 to 0 and 39 to 1 respectively) at that same time. This is in line with Rathbun's (1883, p. 143) statement that while P. montagui and Dichelopandalus Icptoceros are often associated with P. borealis over soft bottoms, they are not only the most plentiful in shoaler water, but occur on gravelly and sandy bottoms as well as on mud. Our catches of fishes, in August, 1936, were similarly dominated by a group of 5 species, in combination, namely: by rose fish (Scbastcs marinus), silver hak
