SABELLIDES AND SERPULIDES 2OI 



Kadiak, July 3, several specimens. Their tubes, which are semi- 

 transparent, horn color, with more or less foreign matter adhering in 

 patches, are attached in clusters or colonies. 



PARASABELLA MACULATA sp. nov. 

 pi. xxvin, figs. 8, 9; pi. xxxm, figs. 8, 12, 33 ; pi. xxxiv, fig. 2 ; pi. xxxvi, 



figs. 12, 15, l6, 21, 22. 



Type locality. Kadiak. 



A rather long, slender species, yellowish white, with the branchiae 

 irregularly spotted with brown, each rachis having its two outer edges 

 marked by dashes and spots of dark chocolate brown, and the pinnae 

 banded with a lighter shade. 



Segments rather long and well defined, about 70 in number, of 

 which 8 belong to the thorax, where the fascicles of setae are in nearly 

 straight series. 



Branchiae about 14 pairs ; not joined by a basal web, narrow, with- 

 out noticeably thinner edges ; the pinnae of moderate length, gradually 

 decreasing toward the end, leaving a comparatively long, rounded, 

 tapered, naked terminal portion. 



Eyes not discernible. 



Collar well developed, round, of nearly uniform depth, arising 

 abruptly a little above the dorsal fascicles of setae, and ending in two 

 small ventral lobes. 



Oral membrane conspicuous, tentacles long, broad at base, with an 

 opaque, rib-like median portion tapering into the long slender end. 



Dorsal furrow conspicuous on the first three segments. 



Length about 35 mm. ; branchiae about 10 mm. ; breadth at base of 

 thorax 3.5 mm. 



Kadiak, July 3, one specimen. 



Although so very dissimilar in general appearance, this species is 

 very much like the preceding in the coloring of the branchiae and form 

 of most of the setae, but those of the tori do not appear to have the 

 conspicuous split seen in that species (pi. xxxvn, fig. 30). 



PARASABELLA sp. 



Type locality. Pacific Grove, California. 



A very small colorless specimen, destitute of branchial lobes, has 

 the round bilobed collar and form of setae characteristic of this genus. 

 It has 8 thoracic and 50 abdominal segments. 

 Length 1 2 mm. ; of thorax 3 mm. ; breadth 2 mm.
