continues in posterior segments. This is followed inferiorly by three or 

 four composite falcigers in which the appendage is longest (Fig. 4) in 

 anteriormost segments, and diniiiu'shcs in proportionate length farther 

 back (Fig. 5) ; the distal end is falcate; the cutting edge has a few long, 

 slender teeth in a single row. Each of the last few segments has, in addi- 

 tion, an inferiormost simple, slightly curved, spinelike seta (Fig. 6) 

 directed ventrolaterally. Acicula occur singly in a ramus; each is a slender 

 rod, distally club-shaped (Fig. 7). 



1 he posterior end of the boily terminates in a pair of short, laterally 

 directed, clavate processes (Fig. 2) resembling the dorsal cirri. 



Sphairosyllis calif orniensis is characterized as follows: the epithelium 

 is papillated ; the first segment is reduced to a lower lip and a pair of ten- 

 tacular bases, lying in line with the prostomial eyes ; parapodia have 

 simple setae in superiormost and inferiormost positions, and composite 

 falcigers ; acicula occur singly. It is unique for having the paired pros- 

 tomial antennae inserted far forward, and the median one near the pos- 

 terior end of the lobe. Composite falcigers have a few long teeth limited 

 to the basal half of the appendage. 



Sphaerosyllis calif ornicnsis occurs in San Pedro shelf, in silt and 

 mixed sediments.

The body is long, linear and consists of many segments. The prosto- 

 mium is a simple, triangular lobe without appendages. The first segment 

 or peristomium is a smooth ring which is somewhat biannulated ; all other 

 segments have lateral, biramous parapodia in which notopodia and neuro- 

 podia are ventrolateral in median and posterior segments. Setae are sim- 

 ple, of two kinds, including slender, distally tapering ones and shorter, 

 thicker, distally bifid hooks without a hood. 1 he pygidium terminates in 

 an anal pore bovunled by paired cirri. The alimentary tract is simple, 

 linear, with a pharyngeal region in the first four or five segments without 

 jaws or other hard parts. A single species is known.

The body is long, linear, measures 9 to 10 mm long by 0.275 mm 

 wide and consists of 50 to 58 segments. All segments are smooth, plain.
