of embryonic development in this species is one of interest which 

 the writer hopes to investigate in the future. Enough has been 

 seen to establish the fact of embryonic fission similar probably

 Tubuliporidae. 



Crisulipora occidentalis may be obtained at low tide almost anywhere 

 on the coast of Southern California. It is abundant at Deadmans Island, 

 San Pedro; at various places in and around San Diego Bay: near Point 

 Loma, at Ballast Point, and on the piles on the water front. It has been 

 dredged off the coast, from San Pedro to San Diego in depths ranging from 

 2 to 17 fathoms.
