Algae (Vol. I.). By G. S. West, M.A., D.Sc, etc. Cambridge Univer- 

 sity I 'rcss, 191(1, 475 pp., 25s. net. We must tender our sincere con- 

 gratulations to our valued contributor, Prof. West, and the Cambridge 

 University Press, on the production of a magnificent volume, which will 

 doubtless remain the standard work on the subject for some time to 

 Twelve years ago Prof. West issued his well known 'Treatise on 

 British Fresh-water Algae, ' which was soon out of print. The present is 

 our of two volumes, which will take the place of the Treatise, and will 

 include particulars of the various discoveries which have been made in 

 this fascinating branch of botany in recent times. The present volume 

 contains particulars of the .1/1 tphyceeB, Peridiniees, Bacillaricce and 

 Chlorophycces, with particulars of the occurrence ami distribution of

Freshwater Algae. From the remarkably complete Bibliographies given 

 in each section of the work, as well as from the text itself, it is apparent 

 that Prof. West is master of his subject. Though in a difficult study 

 such as the Algae, illustrations are essential, it must be conceded that the 

 author has more than met the wishes of the most exacting critic. There 

 are nearly 300 figures, and quite frequently, each figure has ten or more 

 separate drawings. For clearness of detail and accuracy of draughtsman- 

 ship, they would be difficult to beat. We arc permitted to reproduce one 

 of them (fig. 236) herewith, which in itself illustrates, by the description 

 given, the thoroughness and interest of Prof. West's volume. 



We have received Vol. I., part 2 of Coleoptera Illiistrata by Howard 

 Notman, 136 Joralemon Street, Brooklyn, N. Y. It consists of 50 plates, 

 illustrating the Carabidce. The illustrations are all enlargeo, and each 

 is supplied with the name, dimensions and particulars of distribution. 

 The illustrations given would be excellent for hand-colouring.
