1. Grimdzilge der Paldontologie {Paldozoologie) ; by Karl 

 A. VON ZiTTEL, revised by F. Beoili. I. Abteilung : Inverte- 

 brata, 4th edition, vi + 649 pp., 1458 text figs., Munich and 

 Berlin 1915 (R. Oldenbourg). — This standard text book of inver- 

 tebrate paleontology has now appeared in the fourth edition. It 

 seems to have been issued from the press during the latter part 

 of 1915, but was not received by the reviewer until August, 1917, 

 and was sent through the International Exchange Bureau of the 

 Smithsonian Institution. The book is much improved over the 

 third edition, having 44 new figures, 87 more text pages, and 

 about 1700 additional generic and other names. The Monticuli- 

 poridse are no longer grouped among the tabulate corals, but are 

 now properly placed among the trepostomatous Bryozoa. On 

 the other hand, the classifications are still conservative and in 

 general much like those of the former edition. c. s. 



2. JPalceozoic Crustacea, the pxiblications and notes on the 

 genera and species daring the past twenty years, 1895-1917 ; by 

 Anthot^y Wayne Yogdes. Trans. San Diego Society Natural 

 History, 1917, 141 pp., 5 pis. — In 1890 and again in 189*^3 Vodges 

 presented bibliographies of Paleozoic "Crustacea" from 1698 to 

 1889, and in 1895 he issued a supplement comprising the litera- 

 ture up to that date. Now he gives us another catalogue of the 

 literature on the Paleozoic Crustacea from 1895 up to 1917. 

 These bibliographies are annotated and give the genera and spe- 

 cies discussed in each work, and they will therefore alwaj^s be of 

 the greatest aid to paleontologists. Now if some one would pub- 

 lish an index to all the names in these four publications, our cup 

 of joy would be full. The whole work has been one of love, and 

 all through the author's military career he has devotedly applied 

 himself to these bibliographies and has in addition assembled one 

 of the best libraries on paleontology. We salute the general, and 

 he has our congratulations on making the work of paleontologists 

 easier and more certain of good results. c. s. 



3. The Lower Cambrian Hohnia fauna at T0mten in iVor- 

 way; by Johan Ki^r. Yidenskaps. Skrifter, I. Mat.-Naturv. 

 Klasse 1916, No. 10, 112 pp., 14 pis., 15 text figs., 1916 (= 1917). 

 — In this very important and far-reaching contribution to inver- 

 tebrate paleontology and stratigraphy, the author describes the 

 Lower Cambrian fauna of twenty-one species found at T0mten in 

 southern central Norway. The greatest value of the study lies 

 in the very detailed description of the trilobites and in the criti- 

 cal analysis of this fauna, with others, as to its time and provin- 

 cial relations. His restorations of the trilobites Hohnia and 

 Kjerulfia (new) are excellent. Good reasons are given showing 

 that Paradoxides could not have originated in Olenellus or in 

 any allied genus, but that they are parallel families having origi-
