NO. 3667 POLYCHAETES—BANSE AND HOBSON 1% 
have hairs as stated by Imajima (1966). There is very faint serration 
at the tips of the shafts of the upper compound setae as well. 
Found at stations 5 and 6. New for the eastern North Pacific. 
Previously known from Japan. 
Syllis (Typosyllis) harti Berkeley and Berkeley 
Ficurss 4h, 7 
Our many specimens have been compared with the type material 
(USNM 32671), and we can add to the description by Berkeley and 
Berkeley (1938): The pharnyx extends through the tenth to twelfth 
setigers. There are the usual 10 soft papillae on the outside and, 
alternating with them, rows of four small soft papillae (fig. 4h). The 
proventricle has 40-60 rows of papillae and extends in the type 
through 12 setigers and in our material through 9-11 setigers. The 
ends of the shafts of median (fig. 42) and lower setae from the thirteenth 
and forty-first feet of the type bear minute teeth. The blades are 
coarsely serrated and have subbidentate tips. The blades of the upper 
setae are about twice as long as those of the median setae but are 
less coarsely serrated and have bidentate tips (fig. 47; see also original 
description, Berkeley and Berkeley, 1938). 
The species reproduces by stolons. The intestines of all our speci- 
mens are empty.

Paragnath groups VII and VIII of specimens from the San Juan 
Archipelago collected by M. H. Pettibone (USNM 28458, 28460, 
28463, and 28464) form five subgroups of pectinate paragnaths 
(sometimes in a double row), rather than a continuous band as 
stated by Hartman (1954) for P. bicanaliculata from Vancouver 
Island. Ehlers (1868) described six subgroups of two rows each for 
his P. agassizt from the Strait of Georgia and from Mendocino (see 
also Izuka, 1912).

A fairly relaxed specimen with about 145 setigers is just 20 cm long. 
Found at stations 2 and 7. New for Puget Sound. Previously known 
from southern California and Guatemala.
