Halosydna carinata Moore 



Halosydna carinata Moore (1903), p. 417, pi. 23, figs. 16-17. 

 Collected in haul L-1, off San Diego in 21 to 28 fathoms on rock. 

 Other specimens, from an unknown locality, agreed with Moore's 

 description except with respect to the structure of the notopodial 

 setae. Dorsally there are a few of the forms described by Moore 

 (1903), but ventrally there is a tuft of much longer delicate sharp- 

 pointed setae, with comb-shaped teeth in two rows throughout the 

 greater part of the seta, but not extending to the tip.

Collected from Yakutat, Alaska; Alki Point, Puget Sound; Ana- 

 cortes. Wash. ; Cape Mendocino ; and San Pedro. 



Polynoe fragilis Baird 



Lepidonotus fragilis Baird (1863), p. 108. 

 Halosydna fragilis Baird (1865), p. 191. 



Polynoe fragilis Johnson (1897), p. 179, pi. 7, figs. 36, 45; pi. 8, figs 52, 

 52a-6. 



Collected from Pleasant Beach, Port Orchard, Salmon Bay, and 

 Seattle, Wash. 



The collection contained one bottle with a single specimen labeled 

 Polynoe commensalis, but with no record of the identifier. It may 

 have been identified as the species to which Webster (1879, p. 10) 

 gave the name Lepidametria commensalis, but as it had lost all elytra 

 and cirri, I was unable to be certain as to its position. 



Lepidonotus squamatus Linnaeus 



Aphrodita squamata Linnaeus (1776), p. 1084. 

 Polynoe squamata Johnson (1897), p. 166, pi. 7, fig. 30.
