Publication 2440, 55 pp., 9 pis., 11 text figs., 191V. — This splen- 

 did memoir demonstrates that not only the European genus Scy- 

 phocrinus but even the highly specialized Bohemian species S. 

 elegans Zenker occurs abundantly in the Devonian of the United 

 States. Further, that the bulbs long known as Camarocrinus 

 are the roots and not the floats of Scyphocrinus. c. s. 



6. Oil a new hydrozoan fossil from the Torinosu-Umestone of 

 Japan ; by Ichiro Hayasaka. Science Reports, Tohoku Impe- 

 rial University, Sendai, Second series (Geology), iv, No. II, pp. 

 55-59, pi. 14, 1917. Geological and geographical distribution of 

 Giganiopteris ; by Hisakatsu Yabe. Ibid., pp. 61-73, pls.l5, 16. 

 .Problems concerning the geotectonics of the Japanese islands : 

 critical reiiiews of various opinions expressed by prevsioiLs authors 

 on the geotectonics ; by H. Yabe. Ibid., pp. 75-104. 



Hayasaka describes a new genus of stromatoporid related to the 

 Permian (India) Gircopora and he therefore calls it Gircoporella 

 semiclathrata. It is from the Lower Cretaceous. 



In the second paper Professor Yabe discusses the distribution 

 of the three Asiatic and the one American species of Gigantop- 

 teris. This most interesting cycadofilic genus ranges from the 

 Lower Permian into the Lower Triassic. Mr. Koiwai describes 

 and illustrates the three Asiatic species, one of which is thought 

 to be new but not named because of its very fragmentary preser- 

 vation. 



The third paper, a most valuable one, sets forth the geotec- 

 tonics of the Japanese islands as understood by Naumann, Harada, 

 Suess, Ogawa and Yon Richthofen, beginning in 1885 and now 

 brought more or less up to date by Yabe. We are soon to receive 

 from Professor Koto his great work on the Geology of Japan, and 

 then Yabe is to return to the subject here so well compiled.

De. Robeet Bell, formerly chief geologist of the Geological 

 Survey of Canada, died recently at the age of seventy-six years. 



De. DeLoene D. Caienes, a graduate of Queens (1905) and 

 of Yale (Ph.D., 1910), and an active member of the Canadian
