Hay, Oliver P, Contributions to the 

 knowledge of the mammals of the 

 Pleistocene of North America. 



Proc. U. S. Nat. Mus., 

 48, No, 2086, Apr. 

 8, 1915, pp. 515- 

 575, pis. 30-37, figs. 

 1-5. 

 Describes a new species of 

 bison, Bison sylcestris, from 

 Ohio ; a new species of musk-ox, 

 Bootherhim nivicoleus, from 

 Alaska ; B. sargenti Gidley, 

 from Michigan ; a new species 

 of horse, Equus hatcher i, from 

 Nebraska ; and a new species of 

 horsej E. francisci, from Texas. 

 Much of the paper is occupied 

 by measurements made on the 

 skulls of various species of 

 equids, having in view the de- 

 termination of the extent of 

 variations in the wild species. 

 Application is made of the re- 

 sults to determine the origin of 

 the supposed composite species, 

 Equus caballus.

Paleozoic Stelleroidea with special 



reference to North American As- 



teroidea. 



Bull. U. 8. Nat. Mus., 

 No. 88, Mar. 20, 

 1915, pp. 1-311, pis. 

 1-38, figs. 1-41. 

 This' monograph contains an 

 exhaustive study of all known 

 Paleozoic Asteroidea and Au- 

 luroidea, and a shorter presen- 

 tation of the Ophiuroidea. The 

 first 51 pages are devoted to a 

 discussion of the terminology, 

 development and evolution of 

 Paleozoic Stelleroidea, the re- 

 mainder dealing with the de- 

 tailed descriptions of genera 

 and species. A complete bibli- 

 ography is included. Based 

 largely upon the collections in 

 the L^. S. National Museum, 

 particularly the Harris and Ul- 

 rich collections.

 figs, 1-5. 

 An account of the toothed 

 birds of the Cretaceous beds of 

 Kansas, prompted by the dis- 

 covery of a fossil vertebra of a 

 bird in the Clagett formation 

 (Judith River) of Montana. 

 The specimen referred to is in 

 the U, S, National Museum, and 

 will be figured later in The 

 Auk.

Smithsonian Misc. 



Colls., 64, No, 2, 

 July 22, 1914, pp. 

 77-156, pis. 4-23. 

 A preliminary paper on a 

 fossil algal fiora from the Al- 

 gonkian formations of the Cor- 

 dilleran area of western Amer- 

 ica. Algonkian algal flora is 

 correlated with modern blue- 

 gi-een algae. An outline of Al- 

 gonkian geologic continental con- 

 ditions and sedimentation, and 

 a biologic discussion of the 

 algal flora and the traces of 

 contemporaneous aquatic fauna. 

 Suggests the algae as the ex- 

 planation of immense reefs or 

 banks of Algonkian limestone, 

 and bacteria as the agent in 

 their formation. Describes S 

 new genera of Algonkian algae, 

 with 12 new species described 

 and illustrated, and other de- 

 scriptions and illustrations of 

 modern algal flora.
