LOPIIOPODA. 
In the larva of Alcyonella, according to the observations made by H. 
Nitsche, the vent is first on the oral face inside the tentacles, as in the 
Endoprocta, and afterwards changes its position, as the circle of cilia is 
transformed into the horseshoe-shaped disposition of the tentacles. J. 
Barrois, 1. c. pp. 89-92. 
Cristatella. Observations on its development by Hatschek, 1. c. 
ENDOPROCTA. 
The Endoprocta are, according to Yogt and Hatschek, 1. c., the pro- 
totypes, or lower, less differentiated form of the Polyzoa ; according to 
Joliet, 1. c., the most developed of them. Salensky, 1. c., comes to the 
conclusion that the origin of the buds is the same in both, and that the 
ectoderm of the Endoprocta corresponds to the zooecium of the other 
Polyzoa, the intestine and tentacles to their polypid, and the parenchyma 
to the mesoderm.
