spicuous presetal cirrus-like lobe. As in the first parapodium, the 

 dorsal cirrus extends for more than half its length beyond the para- 

 podium, while the ventral cirrus is much smaller than that in the 

 first parapodium. The greater number of neuropodial setae each have 

 a short terminal joint provided with a strong apical tooth and a row 

 of sharp spines along one edge (pi. 11, fig. 11), while a few, clorsally 

 located, resemble the notopodial setae in form. 



In the type, beginning at about the end of the anterior quarter 

 of the body, each notopodium has a few hooked setae (pi. 11, fig. 12). 

 The posterior parapodial lobes are much more slender than the anterior 

 ones. The anal cirri were absent from the type, but present in a 

 fragment in the same bottle. They are longer than the tentacular 

 cirri, and very slender. On the body wall, at the base of each cirrus, 

 is a very prominent black spot. 



Collected from Fort Point, San Francisco Bay. 



Type in the Museum of the University of California ; co-type in 

 the American Museum of Natural History. 



Family NEPHTHYDIDAE 



I have attempted to distinguish between the species in this collec- 

 tion, though it is probable that Moore (1911, p. 243) is correct in 

 thinking that all of the California species belong to Nephthys coeca.
