Fusulina limestone of Sicily and the Salt Range and Himalaya 

 of India. No comparison at all can be made with those of the 

 Mississippi Valley, for the oldest part of the Guadalupian .is 

 younger than any part of the Kansas "Permian." "Probably 

 the best correlation is that of the Guadalupian on one hand with 

 the Artinsk and Permian on the other" (p. 40). "It would be 

 unwise at present to correlate the Guadalupian series with any 

 definite stage of the Russian section " (p. 41). 



The Guadalupian faunas consist essentially of Protozoa (9), 

 Sponges (24), Bryozoa (44), Brachiopoda (128), Pelecypoda (45), 

 and Gasteropoda (42). The more characteristic elements are the 

 large and very abundant Fusulina elongata, of brachiopods 

 Geyeretta (1 species), Itichthofenia (1), Leptodus or Lyttonia 

 (2), Aulosteges (5), Productus (25), Pugnax (12), Spiriferina (9), 

 Dielasma (5), Dielasmina (2), JVotothyris (3) and Heterelasma 

 (2). The Mesozoic bivalve genus Gamptonectes seems also to be 

 present. 



The new genera are, of sponges Anthracosycon, Virgida, 

 Pseudovirgula, Stromatidium, Guadalupia, Polysiphon, Cysto- 

 thalamia ; a supposed cystid, Coenocystis ; of brachiopods, Heter- 

 elasma ; the pelecypod Protrete / the cephalopod Peritrochia 

 and the trilobite Anisopyge. 



We have in this book a valuable contribution to Permian 

 faunas, but as the life is that of a distinct province harmonizing 

 best with those of subtropical waters, there is not much guidance 

 to be derived from it in ascertaining the exact time equivalent of 

 the "Permian" of the Mississippi Valley. c. s. 



13. Ganibrian Geology and Paleontology. No. 5. — Cambrian 

 Sections of the Cordilleran Area • by Charles D. Walcott. 

 Smithsonian Miscel. Coll., 53, 19<>8, pp. 167-230. — Here are 

 described in detail six extensive Cambrian sections ranging in 

 thickness from 5670 to over 13,000 feet. They are located in 

 California, Nevada, Utah, Montana and British Columbia. 

 Throughout the sections the fossils are listed and it is seen that 

 Olenellus has a range of at least 4900 feet. One of the interest- 

 ing facts is the recording in the Pacific province of the genus 

 Holmia, one that is usually regarded as diagnostic of the Atlantic 

 province. Billingsella coloradoensis ranges throughout the Middle 

 Cambrian into the Upper Cambrian. The paper is illustrated by 

 many half-tones of these the finest Cambrian sections. c. s. 



14. Mount Stephen Pocks and Fossils ; by Charles D. Wal- 

 cott. Alpine Club of Canada, Calgary, Alberta, Sept. 1908, pp. 

 232-248, plates 8. — The author describes in this paper the great 

 Cambrian section, Mount Stephen, at Field on the line of the 

 Canadian Pacific railway. Any one collecting the fine Middle 

 Cambrian fossils first noted by Rominger will want this pam- 

 phlet as his guide to the locality and for the determination of his 

 fossils. c. s.
