This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 Excerpt: ...containing a Halosydna insignis from Port Townsend, Washington. Peisidice aspera Johnson. Peisidice aspera Johnson, Proc. Cal.Acad. Sri., (3), (Zool.), Vol. I, pp. 184,185. Single examples of this curious little polychsete occur at three rather widely separated stations. The elytra are very stiff and rigid, apparently due to a hard brownish secretion which is deposited in layers, thus giving the appearance of concentric lines of growth. Sand grains adhere to and become imbedded in this substance, especially along the ridge of the scale. This same secretion renders the body brittle, but no sand grains are borne on this region of these specimens. The hairs of the marginal fringes are very unequal, the longest being as much as of the long diameter of the scale. Many of the elytra are marked with dark brown central spots. Stations 4228, vicinity of Naha Bay, Behm Canal, southeastern Alaska, 41-134 fathoms, gravel and sponge; 4235, vicinity of Yes Bay, 130-193 fathoms, gray mud; 4253, Stephens Passage, 131-188 fathoms, rock and broken shells. APHRODITIDE. Aphrodita japonica Marenzeller. Aphrodila japonica Marenzeller, Denks. K. Akad. 'issensch., Wien, XLI, (1879), pp. Ill, 112. From the Gulf of Georgia to the head of Behm Canal this species is common and especially so wherever muddy bottoms occur. These specimens differ in no respect from those taken in the Albatross dredgings off the coast of Japan in 1900. The neuropodial setaj are unusually prominent and slender and when young their tips are incased in a densely hairy sheath, which later wears away, leaving the point smooth. The notopodial setae are completely imbedded in the felt and are seldom visible. They are slender, soft, curved, pale brown, roughened toward the end and have the tip hooked. Gener...
