It is very interesting to note the occurrence of this remark- 

 able species within our boundary. The species was not hitherto 

 known to exist on the Pacific coast. As found in the Atlantic, 

 Otir specimens are also epiphytic on the leaves of Zostera marina. 

 It is also on Phyllospadix. It is very likely to be found on the 

 American side of the Pacific Ocean.
