acicular fascicles of (in the type) from eight (on IX) to twenty-six (on 

 XXV), decreasing to eleven or twelve at CL, the cotype bearing about 

 one-third as many more. Stems slightly curved and slightly enlarged 

 distally to form an oblique socket, each side of which bears a small 

 brush of hairs, none of which is enlarged. Appendages very long, 

 slender, tapering, slightly curved, with a border of minute serrations; 

 their length is from more than one-half to nearly the depth of the 

 neuropodia and they vary little in the different regions. 



Proboscis of type fully extended, clavate, 7 mm. long, 1.8 mm. in 

 distal and 1.2 mm. in basal diameter. Orifice surrounded by nineteen 

 rather prominent, compressed ovoid papilla?. Greater part of surface 

 smooth, with six very obscure longitudinal ridges becoming gradually 

 more roughened toward the base. Papillse confined to basal one-sixth 

 or less, arranged in six longitudinal rows on each side separated by 

 dorsal and ventral intervals, of which the former is the greater and 

 about equals the width of the papillated areas. The papillae are 

 slightly flattened and the posterior face is brown. Each row contains 

 from nine or ten (ventral) to twelve (dorsal), the increased number 

 resulting from a few papillse placed irregularly at the anterior end of 

 the more dorsal rows. In addition to the paired series, about four or 

 five very small papillae form an irregular dorso-median row. Except 

 for the greater contraction the proboscis of the cotype is exactly 

 similar. 



Color of type confined to a brownish tinge on the dorsum and 

 notocirri; cotype uniform purplish-brown. 



Type locality, vicinity of Monterey Bay, M. H. Spaulding. The 

 •cotype was taken at San Diego by E. C. Stark. 



Phyllodoce (Carobia) castanea Marenzeller. 



Carobia castanea v. Marenzeller, Denkschr. K. Acad. Wissensch., Wien, 

 XLI (1879), Math-naturw. CL, 2d Abth., pp. 127, 128, Tab. Ill, fig. 2. 



A much contracted specimen which agrees very closely with 

 v. Marenzeller's description was dredged by Mr. Spaulding on July 12, 

 1903, at Delmonte wharf, near Monterey Bay. Length 21 mm. ; 

 segments 160. 



Prostomium regularly subovate, about as broad as long, truncate 

 posteriorly with a very slight median emargination; no anterior 

 constriction or furrow. Eyes very large, dorso-lateral, about one- 

 fourth diameter of prostomium and about an equal distance apart. 

 Tentacles lateral and ventrolateral, near anterior end of prostomium, 

 directed almost laterad and very little forward, acutely subulate, 

 thickened toward base, the dorsal pair as long as prostomium, the 

 ventral two-thirds as long.
