The anterior part of the post- septal is cov- ered by wart- like eleva- tions, under whichtheduct is much twist- ed ; no warty elevations in the posterior part of the postseptal ; stalk short and thick; duct narrow and difficult to follow. Lymphocytes variable, ovoid, more or less pointed. Color of formalin specimens decidedly gray. The body is smooth and rather glossy. Locality. — Metlakatla, Alaska, June 4, 1899, Prof. W. E. Ritter. Under decaying seaweeds. A single specimen from Popof Island, col- lected by Prof. Trevor Kincaid. The species is named for Dr. C. Hart Merriam. Characteristics.—The specimens which apparently had been placed directly in the formalin solution had not contracted sufficiently to show any deep intersegmental grooves. This characteristic made it easy to pick out the species from others collected at the same time and in the same locality. The intersegmental grooves between the first few anterior somites are dorsally so shallow that it is with difficulty that the somites can be distinguished one from the other. Setce. — In the majority of fascicles the setc^ diminish toward one side, but while in some the diminution is toward the ventral interval, in others it is toward the lateral interval, following apparently no con- stant Figs. 47 and 48.
