SIGALEONIDiB. 



Pholoe minuta (Fabricius) Oersted. 



Pholoe minuta (Fabricius), Mcintosh, Monograph of British AnneHds, Part 

 II, (1900), pp. 437-442. 



A perfect example nearly an inch in length was taken at Station 4272, 

 at Afognak Ba}^, Afognak Island, Alaska, in 12-17 fathoms, on a bottom 

 of sticky mud; and a few fragments of a very small individiual prob- 

 ably of this species from a bottle containing a Halosydna insignis from 

 Port Townsend, Washington. 



Peisidice aspera Johnson. 



Peisidice aspera Johnson, Proc. Cal. Acad. Sci., (3), (Zool.), Vol. I, pp. 184, 185. 



Single examples of this curious little polychffite occur at three rather 

 widely separated stations. The elytra are very stiff and rigid, appar- 

 ently due to a hard brownish secretion which is deposited in layers, thus 

 giving the appearance of concentric lines of gro\\i:h. 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. 



APHRODITID^. 

 Aphrodita japonica Marenzeller. 



Aphrodita japonica Marenzeller, Denks. K. Akad. Wissensch., 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 dredg- 

 ings off the coast of Japan in 1900. The neuropodial setae 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, rough- 

 ened toward the end and have the tip hooked. Generally the color is 

 very dark — almost black — and the felt is dull, probably the result of 

 staining by some constituent of the mud in which they live. The palpi 

 are white. The specimens vary in length from 14 to 80 mm.
