Moore has described _Eulalia (Sige) bifoliata_ from Monterey Bay; but as the ventral tentacular cirrus of II is described and figured as cylindroconical, that species cannot be properly referred to _Sige_ as now restricted. _Anaitides heterocirrus_ sp. nov. Close to _A. mucosa_ (Oersted) in the characters of the proboscis, having similarly six rows of papillæ proximally on each side with the number in each series normally nine or ten, but distinct in the form of the cirri. The three first pairs of normal foliaceous notocirri much smaller than the succeeding ones and different in shape, being very broadly and evenly elliptic, the distal end of the third, e. g., broadly rounded, not conspicuously narrowed as in _mucosa_. In the average parapodia of the middle region of the body the neurocirri are obviously broader with the tip stouter and less acute; and the notocirri, while in general somewhat similar in form, are more elongate with a more pronounced ventral lobe, the distoectal angle more acute and more produced, while the distomesal corner is more rounded, and the proportionate width across the distal end appears less. The prostomium very broadly cordate, notched or constricted at the sides near the anterior third which is distally broadly rounded; tentacles inserted on each side at or just distad of the constriction, conical and of moderate length; caudal margin conspicuously angularly incised at middle and there embracing a conspicuous nuchal papilla. Eyes about twice their diameter apart. The type is incomplete caudally, at present consisting of ninety-five somites and having a length of 35 mm. with a maximum width, exclusive of parapodia, of 2 mm. The body at present has a purplish tinge. Dredged at 10 fathoms on Aug. 27, 1917. Type--M. C. Z. 2, 146. SYLLIDAE _Typosyllis bella_ sp. nov.
