Caulleriella annulosa (Hartman), new combination 
FiGurE 7a 
Tharyx annulosus Hartman, 1965a, p. 167; 1965b, p. 59. 
Among Tharyz species kindly sent by Dr. O. Hartman, there are 
specimens of T. annulosus from station SL 4, off New England (Hart- 
man, 1965a). There are acicular spines (fig. 7a) in neuropodia of the 
middle section of the body, and in both rami of the posterior section, 
in addition to capillary setae. These spines were not mentioned in the 
original description. We transfer the species therefore into Caulleriella 
as defined by Hartman (1961). 
Chaetozone Malmgren 
Because we have seen six North Pacific species of Chaetozone, a 
key for the temperate and subarctic North Pacific species is given. 
It considers primarily characteristics of the front end. Chaetozone 
abranchiata Hansen is not included in the genus on the basis of the 
original description (from Hansen, 1882; Levinsen, 1883) and that 
by Moore (1903), which report only capillary setae but not acicular 
spines. There are two North Pacific records that are not included in 
the key: Ushakov (1950) briefly described a Heterocirrus species with 
unidentate acicular spines starting in the fifteenth neuropod, which 
well might have been a Chaetozone species. Hartman (1963) mentioned 
a Chactozone species from California with neuropodial spines present 
from the fifteenth segment.
