is presented of the Cyelostomata, with 5 sub- 

 orders, on© of them, " Ceramoporoidea," being 

 new; a natural division given of the Trepo- 

 stomata and the most recent work on the 

 ■Cheilosiomata is included. 



In the Brachiopoda (Charles Schuchert) 

 the form of the chapter and the general prin- 

 ciples of the classification have been retained, 

 but the latter has not only been elaborated 

 to such completeness as to assemble all out- 

 standing generic divisions of which the later 

 years have added no small number, but have 

 been illuminated by the expression of phylo- 

 genetic lines and terminals. This procedure 

 has made necessary the introduction of a good 

 many new divisions of supergeneric value, but 

 it conveys a conception of developmental rela- 

 tionships never before so well expressed. 



The chapters on the Pelecypoda, Gastropoda 

 and Pteropoda have undergone no material 

 changes except for the inclusion of new ge- 

 neric terms (W. H. Dall), but in the Cephalo- 

 poda by J. Perrin Smith there are notable 

 expansions in both matter and illustration. 

 For some reason the Nautiloidea have been 

 left pretty much as they stood before, though 

 a great deal of work has been done on the 

 group in the last 14 years by Germans and 

 Americans; but the Ammonoidea have been 

 amplified by many new cuts of Carbonic, 

 Permic and Triassic forms. It will surprise 

 many students of this group to find Hyatt's 

 classification, adopted in the first edition, quite 

 entirely cast out in favor of the German 

 taxonomy as expressed by Zittel and of late 

 years amplified by European students and by 

 Dr. Smith, himself a collaborator with Pro- 

 fessor Hyatt. The present classification is in 

 a way a trial adjustment of the old and the 

 new. 



The Trilobites have been revised by P. E. 

 Raymond, who has enlarged the generic list 

 from 55 genera in 14 families, as in the first 

 edition, to 126 genera in 28 families; a state- 

 ment which indicates the persistent and grow- 

 ing interest in this group of fossils. The 

 principles of the classification are those fol- 

 lowed by Beecher in the first edition. The re- 

 viser has incorporated his own interpretation 



of many old and rather vaguely defined names, 

 such as some of Corda's and Angelin's, with a 

 generous number of new generic conceptions 

 based upon his own researches. 



The Branchiopoda and Ostracoda have been 

 brought up to date by R. S. Bassler with a 

 considerable number of new figures. The 

 Cirripedia and Malacostraca (by "William T. 

 Caiman; Phyllocarida by J. M. Clarke) are 

 not materially unlike their earlier presenta- 

 tion, while the Arachnida-Merostomata (J. M.. 

 Clarke) have been considerably revised with 

 some substitution of old for new illustration, 

 especially of restorations based on the re- 

 searches recently published by Clarke and 

 Euedemann. The Arachnida-Embolobranchi- 

 ata (Alexander Petrunkevitch) are brought 

 into line with recent discoveries with some 

 additional illustration, and the Myriapoda 

 stand very much as they were left in the old 

 edition. 



Mr. Anton Handlirsch's chapter on the 

 Insecta is, a wholly new and original document 

 of thrice the text matter and twice the illus- 

 tration of the former edition. The general 

 discussion and the classification are so entirely 

 unlike the original that even a trace of the 

 latter is hard to find. It may well be regarded 

 as the best present expression of information 

 regarding this group.

School Health Administration. By Louis W. 

 Eapeer, New York Training School for 

 Teachers. Published by Teachers College, 

 Columbia University, New York City. 

 Part I., pp. 1-YO, gives an outline of na- 

 tional health problems in their relations to 

 the school. Part II., pp. 71-294, summarizes 

 the findings of an intensive study which the 

 author has made of the methods and results 

 of school medical service in twenty-five typical 

 cities in the eastern states. Part III., pp. 295- 

 358, oilers a tentative standard plan for the 

 administration of school health work. 



The book is the fruit of several years of 

 first-hand investigation of the methods of 

 medical inspection as it is actually carried on.
