parative measurements, including 

 one giving the indices showing the

Knowlton, F. H. Results of a paleo- 

 botanical study of the coalbearing rocks 

 of the Raton Mesa region of Colorado 



and New Mexico. 



Amer. Journ. Sci., 4th ser., 

 35, May, 1913, pp. 526-530. 

 A study of the fossil plants shows 

 that the coalbearing section of the 

 Raton Mesa region, formerly consid- 

 ered as Tertiary and later as Creta- 

 ceous (Laramie), must now be re- 

 garded as in part Cretaceous (Ver- 

 mejo) and in part Tertiary (Raton).

pp. 555-558, pi. 44. 



Discusses the occurrence of Gleich- 



eniaceae in the Paleozoic and Meso-

 paleontology. 



Auk, 30, No. 1, Jan.,1913, 

 pp. 29-39, pi. 3. 

 A study of the types of three species 

 of fossil turkeys convinces the author 

 that Meleagris aUus= M. superbus; 

 M. arUiqua is probably not a true 

 Meleagris and M. celer is not a mem- 

 ber of this family. Some notes are 

 added on the fossil birds of Oregon.

 dam-Hoyt fauna. 



Smithsonian Misc. Colls.,

 pp. 251-304, pis. 37-49. 

 Describes the varied fauna from 

 the Upper Cambrian Potsdam sand- 

 stone and Hoyt limestone of New 

 York State; proposes and defines the 

 name "St. Croixan" in place of 

 "Saratogan"; describes and figures 

 representatives of IS genera, includ- 

 ing the new genus Matherella, and 4 

 new species as follows: Hyolithellus 

 papillatus, Ptychoparia matheri, Pa- 

 godia seelyi, and Dicellocephalus tri- 

 bulus.

 the Lower and Upper Cambrian series 

 of formations. 



Smithsonian Misc. Colls., 

 57, No. 10, Sept. 16, 1912, 

 pp. 305-307. 

 Proposes term " Waucoban " to re- 

 place "Georgian" as group name for 

 formations in Lower Cambrian, and 

 "St. Croixan" to replace "Sarato- 

 gan" as applied to group formations 

 in Upper Cambrian, as in previous 

 paper. 



Cambrian Brachiopoda. 



Monogr. U. S. Geol. Sutv., 

 51, 1912, pt. 1, pp. 1-872, 

 figs. 1-76; pt.2,pp. 1-363, 

 pis. 1-104. 

 Gives results of an exhaustive study 

 of the subject, based on personal in- 

 vestigation, with correlation of all 

 important publications on the sub- 

 ject. Main purpose: To make the 

 work of value to the student of Cam- 

 brian faunas and to the stratigraphic 

 geologist. Describes 44 genera, 15 

 subgenera, 447 species, and 59 varie- 

 ties of Cambrian Brachiopoda, and 3 

 genera, 1 subgenus, 42 species, and 1 

 variety of Ordovician Brachiopoda. 

 Treats Brachiopoda historically, geo- 

 logically, and zoologically. Includes 

 bibliography, table of synonymic ref- 

 erences, general geographic and strati- 

 graphic distribution, evolution, clas- 

 sification, and descriptions and illus- 

 trations of genera and species in part 

 1. In part 2, nearly 400 pages of plate 

 descriptions La addition to the 104 

 plates further illustrating the Brach- 

 iopoda.
