Note. According to A. S. Hassatn Bowerbankia densa is a 
younger state of Valkeria imbricata ; Annals and Magaz. of nat. 
Hist. vit. 1841, p. 363, 364. But in Valkeria and Vesicularia 
from the observations of Farrer and VAN BeENEDEN there are 
8 tentacles not spinous; in Bowerbankia and Laguncula 10—12 
tentacles, besides vibratile cilia, supplied with immoveable setz or 
spines.—Lusia Mitne Epw. (in a note to Lamarck Hist. nat. des 
Ant. s. vert. 2e édit. 11. p. 72) is it Laguncula ?
