JOUKNAL OF ENTOMOLOGY AND ZOOLOGY 205 



Clotcnia occidcntalis Cole 

 Only one specimen found among mussels. 



Halosonia viridintcstUialis Cole 

 A number of these, ten in all, were found as last year among 

 polyzoan masses. 



A}ioplod(ictylus calif ornicus Hall 

 More of these were found than last year, chiefly among the roots 

 of Phyleospadix. Those that were found abundantly under stones 

 were near large hydroids. Thirteen specimens in all were collected. 



Anoplodactylus erectus Cole 

 None of these were found last year, while between two and 

 three hundred were found this season. All but one were taken 

 from tubularian hydroids at Balboa. The one specimen from 

 nearer Taguna was from an uncertain location and was a young 

 specimen. The first lot obtained from Mr. Daniels contained a 

 hundred specimens — immature and young adults, but no specimens 

 with eggs. At a later time large numbers with eggs were obtained 

 chiefly from the older stems of the hydroid masses. On the 

 polyps and in them various stages of development were found. 

 At a later time the life history of this species will be considered 

 more in detail. 



Pyoiogouiim stearnsi Ives 

 Last year only two specimens of this species were obtained. This 

 year twenty-four were collected anci many more might have been 

 taken. No males with eggs were found, but in September a num- 

 ber of very young were obtained. Most of the specimens were 

 found at the bases of medium-sized sea anemones; a few were 

 found well inshore in seaweeds near sea anemones. They seem 

 to be fairly abundant in some places. Often one large one was 

 seen first and then under it one or two smaller specimens were 

 found. When a number were placed in a dish they formed them- 

 selves into a compact ball. They are slow in their movements, and 

 as they are inshore species it may be that they live better in the
