INTRODUCTION. 
Bryozoa literature this year is distinguished by a monograph by Calvet 
(11) in which he gives descriptions of many species ; in another paper 
(10) he gives diagnoses of numerous sub-antarctic forms from the Atlantic, 
several of which are new to science. Michaelsen (82) discusses the 
affinities of Bryozoa , and Neviani (84) continues his bibliography of 
living and fossil forms. He has also written on a collection from the 
Mediterranean. Waters (116) reports on the species from Franz-Josef 
Land collected in 1896 & 1897 by the Jackson Harmsworth Expedition, 
Davenport (22) on the fresh-water forms of the United States, and 
Garrard (40) writes on English fresh-water representatives. 
Stiasny (106) has worked on the excretory apparatus of the Entoprocta.

In one (13) he deals with Egyptian forms; another he devotes to describ-
