Cytologists will be interested in Gorich's (76) memoir on spermato- 
genesis in Sponges and Coelenterata. Guenther (84) has carried on an 
allied enquiry in Hydra viridis ; Retzius (183) too has worked on this 
subject. Schneider (199) has written an interesting note on the origin 
of the genital cells of Ctenophores. 
Paleontological contributions are numerous. Bogatirew (14) adds a 
new genus and six new species of Devonian forms from the Ural district. 
Elles & Wood (54) have now added another part to their monograph on 
British Graptolites. Graptolites from Sweden are described by Holm (105, 
106) and some new species from New York are recorded by Ruedemann 
(196), while Hall (87, 88) reports on those of Victoria. Swedish 
geological notes by Huene (112) include a description of a medusa from 
the lower Silurian. Felix (58-61) has given three memoirs on fossils 
from Egypt and also from the Jura region. Paleozoic corals are discussed 
by Grabau (80). 
Embryology is represented by some very good work this year. Students 
of this subject will be interested in Hargitt's (91, 92) papers on the 
early development of Eudendrium and Pennaria tiarella. Ruedemann 
(195) describes the mode of growth and development of Goniograptus 
thureaui, and Woltereck (233) has followed the development of Velella.
