cellina americana. By observations of their respective stain affinities, 
and their disposition at various periods of the cell metabolism, he shows 
that the nucleoli are not chromatin bodies and come only incidentally into 
connection with the chromosomes to which they in no way give origin. He 
insists upon the importance of an early mingling of gonomeric characters 
in order to ensure perfect larvae, and points out that this supports the 
fact of the nucleoli being unconnected with the gonomery of the cell. 
Cumings (22, 23) in a paper upon the development and metamorphosis 
of Fenestella brings forward evidence that the genetic relation of this 
form to the Cyclostomata proves the latter to be the ancestor of the 
Cryptostomata and thus of the Cheilostomata. He shows a tendency 
towards concentration of the earlier developmental stages, and explains 
the large size of the protcecium in ancient types as due to a less degree of 
acceleration. Miss A. Robertson (64, 65) has a note on the Embryology 
and Embryonic fission of the genus Crisia ; and also a monograph on 
the Cheilostomatous Bryozoa of the West Coast of North America. She 
criticises Hincks’ diagnosis of the Aetddce. Hallez (34) has a paper on 
rheotropism in Bugula avicularia . 
Calvet (10, 11) gives descriptions of the marine Bryozoa in the 
collection of the Musee Royal at Brussels, and from the zoological station 
at Cette ; Romer (66) a list of Norwegian Bryozoa ; Seeliger (69) a note 
on Bryozoan larvte and metamorphoses. Miss L. R. Thornly (74) has a 
report on Herdnmn’s collection of Polyzoa from Ceylon. 
Ameghino (1) in “l’&ge des formations sddimentaires de Patagonie” 
criticises Hatcher’s views. Neviani (53, 64, 65) continues his bibliography 
of living and fossil Bryozoa, and has a paper on the Eocene fossils from 
Villatorta. Thevenin (72) has a note 'on the Fossils of the Lower 
Carboniferous layer of Djebel Bechar, and Whitfield (80) on a new 
genus and species of Lower Carboniferous Bryozoon. Maplestone (46) 
gives a list of the Fossil Cheilostomatous Polyzoa of the Victorian 
Tertiary Deposits. Lang (42) has a paper on Stomatopora antiqua and its 
related Liassic forms.
