setae on the second tentacular segment, as to be expected in the sub- 
genus Anaitides. A female with polygonal eggs of up to 75u diameter 
was collected in February. 
Found at stations 1, 5, and 8. New for Puget Sound. Previously 
known from Oregon and California.

Many specimens are available that are referred to G. brevipalpa, 
originally described from El Salvador, despite minor differences in 
the notopodial setae. The largest, though incomplete, specimen is 17 
mm long. 
No cilia are visible between the 10 widely spaced terminal papillae 
of the proboscis. Occasionally the unpaired antenna seems to arise from 
a small elevation rather than from the straight anterior margin of the 
prostomium. Also, the posterior margin of the prostomium is straight. 
The longest tentacular cirri reach the twelfth setiger. Tentacular as 
well as dorsal cirri on body segments can be annulated with the joints 
being slightly shorter than wide, or they can appear pseudoannulated. 
The dorsal cirri are alternately short and long; the long cirri surpass the 
short cirri by about one-half their length and are almost as long as the 
body (without parapodia) is wide. Anal cirri are smooth. 
Notosetae are absent on the first three or four setigers although 
aciculae are present dorsally. In posterior notopodia (fig. 36) there 
are three to four short, nearly smooth spines about one-half as thick 
as the aciculae (fig. 3c) and about twice as many forked setae with 
flattened blades and short spurs, distinctly serrated (fig. 3d). The 
greatest width of the blades is about 5y. In addition, two very long 
slightly curved capillaries can occur, which are finely serrated on the 
convex sides. The neurosetae have serrated blades that are almost 
smooth distally. The tips are excavated (fig. 3¢). The blades may 
occasionally have hoods as indicated by the broken line in the figure; 
also one of the notopodial forked setae was found with such a hood. 
The tips of the shafts of the ventral neurosetae are slightly bifid 
when seen from below. The proximal parts of all setae, but not of 
aciculae, are distinctly 2-layered, the core being transversely barred. 
A specimen collected in February is packed with many polygonal 
egos of about 60u-70y diameter. 
Dr. G. Hartmann-Schréder inspected the type of G. brempalpa, 
provided drawings, and permitted us to add the following to the 
description:
