XXXJ.— On Budding in Perophora. 
By GrorGe LEFEVRE *. 
Wuite the Johns Hopkins Marine Laboratory was stationed 
at Beaufort, N.C., during the summer of 1894, I collected 
material for the purpose of studying the development of the 
buds of this Ascidian. Perophora viridis, Verrill, was found 
growing luxuriantly on the wharf-piles, and ample material 
was easily obtained. 
main object in undertaking this work was to compare 
the bud-development of this form with that of Botryllus, as 
described by Hjort f, and especially to determine, if possible, 
the origin of the nervous system.
