spring tides, or by wading beyond low water-mark, are 

 designated as " upper laminarian." 



The Ascidians were especially interesting to me, and 

 engaged a good deal of my attention. 



As I wish to examine them carefully, and have not yet had 

 sufficient time, the list of Tunicata is reserved for a future 

 paper.
