 Found not unfrequently among fuci at and beyond low- 

 water mark, as well as in greater depths among dredged 

 material. Though often found free-swimming, the natural 

 habit of this genus would seem to be symbiotic in the 

 branchial cavities of Ascidians. Our local records are St. 

 Mary's Island, Alnmouth, and Ryhope, among fuci, and in 

 dredgings from four miles off Hawthorn and Marsden in 

 about 25 fathoms (G. S. B.) N.D.
