-some 100 papers on the subject, and has provided a translation of 

 Martin's paper on the Tertiary Fossils which was published in 1895. 

 He also gives two excellent maps of the Islands, drawn by the 

 Jesuit Fathers, and has utilized a sketch of the mineral resources 

 compiled for him from the archives of the Inspeccion de Minas by 

 Luis Espina. Becker accompanied General Otis to Manila, and 

 remained in the Islands fourteen months, but could accomplish little 

 original work because of the attitude of the natives. The paper will 

 be very useful to all subsequent workers, and this seems to be its 

 real purpose.

The first of these four pamphlets contains figures and descrip- 

 tions of species belonging to different genera of Silurian Craniad^, 

 illustrations of the shell-structure of two genera, Pseudocrania and 

 Pseiidometopoma, geographic-geologic tables, and other important 

 matter. In the second contribution two species of a new genus, 

 Aidacomerella, are described and figured. The genus is said to show 

 senile characters ; and also to be a homoeomorph of Aulacorhynchus, 

 a fact referable, the author suggests, to " repetition of develop- 

 ment." The third paper is a later contribution by the same author. 

 It discusses the bearing of certain facts upon studies of Brachiopods, 

 dealing especially with some important anatomical results of 

 F. Blochmann. The author also calls attention to the great confusion 

 in the nomenclature of the shell muscles, pleading for a uniform 

 Latin system. The last paper is a forerunner of a monograph. 

 A new genus, two new subgenera, and several new species are 

 described ; but there are no figures. We much i-egret to find so 

 eminent a palaeontologist as Dr. Walcott countenancing so very 

 undesirable a practice.

A FTER devoting thirty years of almost continuous work to its 

 j^ study and elucidation, the author. Dr. Anton Fritsch, has 

 completed the illustration and description of the Permian Fauna of 

 Bohemia, the marvellous richness of which has surprised all students 

 of paleeontology ; and we congratulate our distinguished fellow- 

 worker upon having lived to achieve so important an undertaking.
