be issued. Lambe's " Eevision of the Genera and Species of the 

 Madreporaria Aporosa and Madreporaria Eugosa " has been pub- 

 lished, and Whiteaves' fourth part of Mesozoic Fossils was issued in 

 November, 1900. 



V. — Canadian PALiEozoic Cokals. — Lawrence M. Lambe has 

 issued part ii of his Eevision of the Genera and Species of Canadian 

 Palseozoic Corals, as Contributions to Canadian Palaeontology, vol. iv, 

 pt. 2. This part deals with the Madreporaria Aporosa and the 

 Madreporaria Eugosa, and consists of 200 pages and 13 plates. The 

 work is of considerable value and seems to have been prepared with 

 much care ; there is little new in it, but that perhaps shows more 

 exactly the attention which the author has paid to his predecessors. 

 Perhaps Nicholson's work might have been more carefully studied. 

 "We do not grasp the author's reasons for rejecting the genus Helio- 

 pliyllum and placing the species under Cyathophylliim, or for using 

 Arachnophyllum in the place of Strombodes. The monograph is 

 a valuable addition to the literature of the Palaeozoic Madreporaria, 

 and we hope the author will be encouraged to continue it. 



VI. — Paleozoic Crustacea. — In the 54th annual report of the 

 New York State Museum, 1900 (1901), J. M. Clarke has some notes 

 on new Crustacea. One of these, the peculiar, eyeless, semi-trilobitic 

 merostome, called Pseudoniscus by Nieszkowski in 1859, has been 

 found in the Eiirypterus dolomites of Litchfield, Herkimer County, 

 and is described under the name of P. Boosevelti. Some of the 

 American specimens are perfect, and Mr. Clai'ke has been enabled 

 to add a good deal to our knowledge of the animal. The other new 

 Crustacea described in his paper are Ceratiocaris pracedens, Emme- 

 lezoe decora, and Estheria Ortoni ; the latter is a Coal-measure form 

 and was found at Carrollton. 



YII. — New Geological Map of the Mont Blanc Massif. — 

 Professors Duparc and Mrazec have issued the map to accompany 

 their memoir on Mont Blanc, published in 1898 by the Societe 

 Physique et d'Histoire Naturelle de Geneve. They had the col- 

 laboration of Dr. Pearce for the Val Ferret region and for the 

 Courmayeur synclinal. The map is based on that of Albert Barbey, 

 but includes Mont Catogne ; its scale is 1 : 50,000, and it is clearly 

 printed and lightly tinted in colour. The publisher is Comptoir 

 Mineralogique et Geologique Suisse, Mined, 6, Eue St. Leger, 

 Geneva. Price not quoted. The publishers also announce the 

 completion of collections of rocks referred to in Professors Duparc 

 and Mrazec's memoir, 49 specimens for 180 francs. 



VIIT. — Geology of the Philippine Islands. — The United States 

 Geological Survey has included in its twenty-first annual volume 

 a report on the Geology of the Philippine Islands. The work was 

 entrusted to George F. Becker, who has produced an admirable 

 resume of the work of all who have gone before, and has added to 

 that observations of his own, taken at considerable disadvantage 

 owing to the unsettled state of the Islands. The report is rather an 

 attempt to bring together all that is known than to provide a new 

 and complete account of the geology of the Philippines. Becker lists
