PEROPHORA VIRIDIS, VERRILI,. 



This Ascidian, which is the only species of Pero- 

 phora known to occur on the Atlantic coast of North America, 

 was first found in Vineyard Sound by Vcrrill (34), and des- 

 cribed by him in 1871. A nev/ species. P. annectens , has re- 

 cently been reported from the coast of California by Ritter, 

 (23) 



Perophora viridis grov/s luxuriantly below lov^-water 

 mark on the wharf piles in Little Harbor, V'oods Holl, and 

 Vineyard Haven, :iartha's Vineyard. I also found it to be 

 equally abundant during the summer months in the harbor of 

 Beaufort, N. C. The colonies form large thick clusters of 

 a beautiful greenish-yellow color, and usually occur together 

 with other Ascidians, and with Hydroids, Bryozca, Sponges 

 and Barnacles, the delicate stolons creeping over and cover- 

 ing the surfaces of everything within reach. 



THE RUDIMENT OF THE BUD. 



Budding in Perophora was first studied by Kowalew- 

 sky (12), v/hose careful work on this form laid the foundation 

 for all subsequent investigation of the process of budding 

 in the Ascidians .
