Length, about 26 mm.

Sige californiensis sp. nov.
Corresponding closely in general characters with S. macroceros (Grube), the genotype. Green in color instead of straw-yellow to brown. Tentacles long and slender as in macroceros, with the median equalling the others in length and inserted close to the base of the latter; tips of tentacles slenderly attenuated. The eyes seem to be proportionately larger than in macroceros. The first segment is reduced above at the sides where the prostomium bulges back on each side; but the middle region is well developed, extending forward on the base of the head as a rounded lobe or flap. Very easily distinguished from macroceros and other known species by the form of the ventral tentacular cirrus of the second segment which, in place of the ordinarily lanceolate foliaceous form, is very strongly expanded above the base, presenting a large rounded lobe in front and an abruptly much more slender tip, with the blade as a whole irregularly twisted. The parapodia very similar to those of the genotype; but the setigerous lobe less acutely and less deeply notched and rather broader across the end along the setigerous line. The notocirri rather more slender and narrowed more evenly distally, not incurved on each side distally so as to leave an elongate tip set off from the rest. The neurocirri similar but more asymmetrical, the upper margin straight or concave, the lower convex. Anal cirri missing. Proboscis not protruded. Total number of segments in the type, which is complete, sixty-eight.
Length, 10 mm.
Type—M. C. Z. 2, 145.
Taken under stones.
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.
