Following Hutton, the autkoi' imagines the process of the 

 destruction and gradual renewal of the solid part of the earth's 

 crust as one of circulation. The granitic magma, once solidified 

 and in part decomposed, undergoes again, when brought into the 

 deeper parts of the earth, a resurrection. Regional metamorph- 

 ism is caused by a weaker form of the plutonic forces which at 

 greater depths manifest themselves in regional resolution, to 

 which latter the general name of anatexis is onyen. l. v. p.

1. Recent Maclreporaria of the Hawaiian Islands and lay- 

 san ; by T. Wayland Vaughan. Bulletin 59, U. S. National 

 Museum, 4to, pp. ix + 222 + index, 96 plates, 1907. — This is 

 another admirable work on the corals, illustrated by excellent 

 half-tone reproductions of photographs, which serve admirably 

 to show the details of coral structures. This work is practically 

 an exhaustive one for the reef corals of the regions treated. It 

 also contains all the deep-sea corals hitherto dredged in the ad- 

 jacent ocean. Many pages are devoted to tables of the local and 

 general distribution, both geographical and bathymetrical, and 

 other matters of general interest. The present work records 129 

 species and varieties, many of them new. Previously only about 

 38 species were recorded. a. e. v. 



2. Madreporaires d' Amboine y by M. Bedot. Voyage de 

 MM. M. Bedot et C. Pictet dans l'Archipel Malais. Geneva, 

 8vo, pp. 143-292, plates 5-50 (double size), 1907.— This is a 

 richly illustrated work on the reef corals of Amboina. The 

 46 plates are double octavo size. They are finely executed re- 

 productions of excellent photographs, many of them enlarged, 

 Amboina has a rich coi - al fauna, and many of the species illus- 

 trated are widely distributed in the Indo-Pacific faunae. This 

 work is therefore of great utility in the study of the corals of the 

 entire region. Numerous new species are described. A. e. v. 



3. An Account of the Crustacea of Norway; by G. O. Sabs. 

 Vol. V, Copepoda, Harpactoidea ; Parts xix, xx, 1907 ; 4to, pi. 

 145 to 160. — This is a continuation of the great work on Nor- 

 wegian Crustacea upon which Professor Sars has been engaged 

 for several years, parts of which have hitherto been noticed in 

 this Journal, from time to time. The plates, as usual, are auto- 

 graphic, drawn by the author. a. e. v. 



4. Worth American Parisitic Copepods belonging to the 

 family Caligidm ; by Chas. B. Wilson. Parts 3 and 4, Panda- 

 rinse and Cercopinae. Proc. U. S. Nat. Mus., vol. xxxiii, pp. 323- 

 490, plates xvii-xliii, 1907. — This is a valuable contribution to 

 our knowledge of a group of Crustacea that has hitherto been too 

 much neglected in America. It includes general accounts of the 

 larval development and habits. It represents a large amount of
