 the following hauls: VI-2, in the outer San Pedro Harbor in 3

Nephthys incisa Malmgren (1865), p. 105, pi. 12, figs. 21-21c. 

 Collected in haul 1165, off La Jolla in 4 to 8 fathoms on soft black 

 shale. 



Family LEODICIDAE 

 In accordance with the rule of priority, Eunice should be replaced 

 by Leodice for a generic annelidan term, Eunice having been in use for 

 insects prior to its use by Cuvier for annelids. Accordingly Leodice 

 will be used in the following descriptions. 



Leodice kobiensis Mcintosh 



Eu7iice kobiensis Mcintosh (1885), p. 278, pi. 38, figs. 12-13; pi. 20a, 

 figs. 1-3. 



A single specimen, probably of this species, was collected from 



Pacific Grove. 



Leodice biannulata Moore 



Eunice biannulata Moore (1904), p. 484. 

 Moore states that the nuchal cirri resemble the tentacles. In these 

 specimens they often resemble the dorsal cirri by having no more than 

 three joints. The ventral crochet and aciculum of the middle region 

 of the body are as in figure 13, plate 11, thus not agreeing exactly 

 with Moore's description. These differences, however, do not seem to 

 me to be of specific importance.
