Pal cue calif oDih'usis Hall 

 Found almost entirely among the zooids of a certain coarse 

 polyzoan. Seventeen specimens collected. 



Lccythorliynchus margiuatHS Cole 

 No new information was obtained about this species. Pound 

 as last year among mussels, now and then in red seaweeds. They 

 can walk quite rapidly through seaweeds. One hundred specimens 

 were collected. 



Ammothclhi hi-uugiiiciilata var. calif omica Hall 

 Found among mussels to a limited degree, chiefly under stones 

 at low tide. Filteen specimens were collected. 



Ammothclla spiuosissima Hall 

 Last year this species was found under stones only, but this sum- 

 mer most of them were found in the roots of Phyllospadix. This 

 species is an inshore form. It is rather slow in its movements and 

 depends upon its form and color to escape observation. The masses 

 of sand caught in the long spines and hairs often help to conceal 

 it. When much disturbed it may fold up and appear to be ciead. 

 Seven specimens were found. 



Ammothclla spinifcra Cole 

 No specimens of this species were found last year. Two were 

 found this summer among mussels out on the points. 



A mmotliclla lubcrcnlata Cole 

 Found as last year, among mussels and coarse polyzoans. 

 Twenty-seven specimens. 



Taiiystylinii nitcrmcdiiim Cole 

 A large number of these, one hundred and thirty-one in all, were 

 found chiefly among polyzoan colonies; also uncier stones and 

 among mussels to a limlteci ciegree. 



Tan\st\liim orbiciilarc Wilson 

 Many of these, eighty-one in all, were found among mussels and 

 older polyzoan stems.
