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.^ During this time, as a guest of Mr. A. 

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

 bara and the neio;h])orino^ island of Santa Cruz, at Mon- 

 terey and the city of Santa Crnz. 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 HydromedusoB found 

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

 Ag., but somewhat different from this species or any 

 Sarsia yet described. 



The bell of the oldest specimen observed has a pointed 

 apex with thick bell walls. The height of the bell is 

 greater than its diameter. The proboscis rarely projects 

 outside the bell opening, its length not being much greater 

 than that of the height of the bell cavity.

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

 the plates and for valuable suggestions.
