the past few years, three similar catalogues have been published. 

 The first one, by the American Museum of Natural History, New 

 York City ; the second, by the New York State Museum, Albany, 

 New York, and now the one cited above. The last, however, 

 records the largest number of species, and is an indication of the 

 great amount of paleontological work done at Washington. 



6. Graptolites of New York. Part I, Graptolites of the 

 Lower Beds ; by R. Ruedemann. N. Y. State Mus., Mem. 7, 

 1904 (distributed March 1905), pp. 457-803, pis. 1-17.— This 

 very valuable monograph had its origin in stratigraphic work by 

 the author, in the slate belt of eastern New York. The book is 

 of the greatest importance, not only to paleontologists and paleo- 

 geographers, but as well to the stratigrapher of the older Paleo- 

 zoic formations. In fact, the work is so valuable that no review 

 could bring out its many excellent points, unless it were of great 

 length, for which space is not at our disposal. In this monograph 

 are treated the late Cambrian and early Ordovician graptolites of 

 America, the species and genera not only being described and 

 illustrated, but also their structure, morphology, reproduction, 

 development, mode of existence, phylogeny, and systematic posi- 

 tion, as well as the bearing of these organisms on the stratigraphy 

 and paleogeography of Ordovician time. c. s. 



7. Mesozoie Plants from Korea; by H. Yabe. Jour. Col- 

 lege Sci., Imperial University, Tokyo, Japan, 1905, pp. 1-59, pis. 

 i-iv. — Here are described 21 species, 3 of which are new. Filices 

 are the most prevalent, being represented by 1] species. 



" It is quite evident that the flora is Jurassic, for neither typ- 

 ically Rhaetic or Cretaceous forms are found in it." 



" On the whole, so far as evidence goes, the writer has little 

 hesitation in announcing the contemporaneity of the Naktong 

 flora of Korea with that of the Japanese Tetori series [about 

 Malm and Dogger], the affinity of the former to those of the cor- 

 responding age in Siberia, China, India and California being 

 apparently more distant." o. s. 



8. Palaeontologia Universalis. — Early in September of the 

 present year, there appeared the first fascicle of the second series 

 of this important publication. Ninety-four species are now rede- 

 scribed and refigured and brought up to date. c. s. 



9. Ninth Annual Report, of the Geological Commission, 

 Dept. of Agriculture, Cape of Good Hope, for 190 % Pp. 181 

 with numerous maps and figures. Cape Town, 1905. — This 

 report contains the description of the detailed survey of several 

 districts in the Colony of the Cape of Good Hope ; thus adding 

 valuable detail to the general works on South African geology 

 which have recently appeared. J. b. 



10. Pock Cleavage; by Charles Kenneth Letth. Bulletin 

 239, U. S. Geol. Surv., 1905, pp. 216. 27 pis.— As noted by Dr. 

 C. W. Hayes in the letter of transmittal, " The paper embodies 

 the results of a very careful and laborious investigation of facts 

 concerning rock cleavage and a discussion of their theoretical
