II.— ANATOMY, &o. 
Prouho (13) continues his investigation of marine Bryozoa. A colony 
is composed of an oozoite and of a certain number of blastozoites. The 
oozoite is the founder of the colony and is the immediate result of the 
metamorphosis of the larva : the blastozoites arise from it by blasto- 
genesis. The term Bryozoite is employed for any member of a colony, 
whether oozoite or blastozoite : it is an indivisible unity, and is not to 
be regarded as composed of two individuals, zocecium and polypide, 
though these terms are still used for convenience of description. The 
zoecium, or cystid, is the protective external skeleton ; the polypide 
includes the digestive, nervous, and muscular organs ; the dual, polypo- 
cystid interpretation of the individual Bryozoite is rejected. The author 
discusses the relations of the adult tissues to those of the larva in Gymno- 
Icemata, taking Fluatrella hispid a as the type. The “ intertentacular 
organ” o£ Gynmolmmata is a genital duct existing only in the sexual
