JOHNSON: POLYCHAETA OF PUGET SOUND REGION. 387 
dr edging's at twelve fathoms and over, but I have never obtained it 
there between tide-marks. I have collected it just above low-water 
mark at Point Cavallo, on the northern shore of the Golden Gate, 
and even higher on the beach near Black Point, Sonoma County, 
about one hundred miles north of San Francisco. The specimens 
from Puget Sound are larger than any as yet collected from the 
California coast, but are inferior in size to New England specimens. 
It is probable that this species will be found to have a wide distri¬ 
bution along the eastern and western shores of the North Pacific, 
comparable to its dispersal on both sides of the North Atlantic.

This, the commonest Polynoid of the western coast of North 
America, is represented in the Puget Sound collection's by several 
slender, darkly pigmented specimens commensal with Thelepns 
crispus , and a single specimen with remarkably thick and tuber- 
culated elytra, obtained by the Columbia University Expedition; 
also by four specimens collected by Miss Robertson at Alki Point. 
With the exception of Harmothoe imbricata this species has the 
widest known distribution along our western sea-board of any of its 
family, ranging from San Diego to Kadiak. 1 South of Point Con¬ 
cepcion it is rare, at least inshore, being almost wholly replaced by 
P. californica. 2 Its remarkable variations according to habitat have 
been described elsewdiere ( vide Johnson, ’97, p. 167). 
The identification of this species with the Halosydna brevisetosa 
of Kinberg (’55; ’58, p. 18), as given by me in the “Preliminary 
Account” (’97), was undoubtedly characterized by too little confi¬ 
dence in the accuracy of Kinberg’s figures and too much influenced 
by his statement that Halosydna brevisetosa was collected in San- 
salito Bay, near San Francisco. As P. insignis is the only Poly- 
1 A small collection of Polychaeta from Kadiak Island, including a single P. insignis, 
was gathered by Mr. Cloudsley Rutter, and kindly loaned to me for examination and de¬ 
scription by Stanford University. 
2 Name changed from P. reticulata Johnson (’97) as the latter name is preoccupied.
