NEW INVERTEBRATA FROM THE COAST OF 

 CALIFORNIA. 



BY J. WALTER FEWKES. 



THE marine animals, described in the following pages, 

 were collected in the months of February, March and 

 April, 1887. l During this time, as a guest of Mr. A. 

 Hernenway of Boston, I carried on studies at Santa Bar- 

 bara and the neighboring island of Santa Cruz, at Mon- 

 terey and the city of Santa Cruz. My attention was es- 

 pecially turned to the Medusae of these regions, and a few 

 observations were made on certain novel genera of other 

 invertebrated animals. 



MEDUSA. 

 SYNCORYNE OCCIDENTALIS sp. nov. 



(PLATE III, FIGS. 2,3.) 



One of the most common genera of Hydromedusa3 found 

 at Santa Cruz, is a Sarsia closely allied to $. rosaria A.

 the Museum of Comparative Zoology at Cambridge. 



I am indebted to the Curator, Mr. A. Agassiz, for assistance in the preparation of 

 the plates and for valuable suggestions. . ,."
