372. Riddle, L. W. Two publications on tropical American lichens. [Rev. of: (1) de 

 Lesdain, Bouly. Lichens de Mexique (Etats de Puebla et du Michoacan) recueillis par le 

 Frere Arsene Brouard. Brochure. PI. 1-31. 1914. (2) Wainio, Edvard. Additamenta 

 ad Lichenographiam Antillarum illustrandam. Ann. Acad. Sci. Fennicae Ser. A. 6: pt. 7. 

 1915.] Bryologist 23: 60-61. 1920. — The reviewer calls attention to these two publications, 

 which contains many descriptions of new species, since neither seems likely to have a wide 

 distribution. That upon Mexican lichens is a wholly independent publication; the other 

 publication, reviewer states, is received in America only at the Smithsonian Institution. — 

 E. B. Chamberlain.

376. Paillot, a. Sur le polymorphisme des Bacteries. [The polymorphism of bacteria.] 

 Compt. Rend. Acad. Sci. Paris 170: 905-906. 2 fig. 1920. — Two bacilli which cause disease 

 in caterpillars are described. When in the caterpillar they present various forms. It is sug- 

 gested that polymorphism may in some cases be due to the effect of the tissues or liquids of the 

 living host.— C. N. and W. K. Farr.

 mannose by Lactobacillus pentoaceticus. n. sp. Jour. Biol. Chem. 42: 273-287. 1920. — See

PALEOBOTANY AND EVOLUTIONARY HISTORY 



E. W. Berry, Editor 



378. Adami, J. G. Medical contributions to the study of evolution. 8vo, 272 p. Mac- 

 millan and Co. : London, 1920. Price, $7.25. 



379. Anonymous. Gymnospermic history. [Rev. of: Seward, A. C. Fossil Plants: 

 A text-book for students of botany and geology. Vol. 4, Ginkgoales, Coniferales, Gnetales. 

 xvi + 543 p. University Press: Cambridge, 1919.] Nature 105:97-93. 1920. It is disap- 

 pointing but perhaps not surprising that the work closes with this group. (See Bot. Absts. 

 3, Entry 2517.)— 0. A. Stevens. 



380. Anonymous. [Rev. of: Wieland, G. R. Classification of Cycadophyta. Araer. 

 Jour. Sci. 47: 391-406. 1919. (See Bot. Absts. 3, Entry 1620.)] Nature 104: 509-510. 1920. 



381. [B., F. O.] The origin of plant life on land. [Rev. of: Church, A. H. Thalassio- 

 phyta and the subaerial transmigration. Bot. Mem. No. 3. 95 p. Oxford Univ. Press: Lon- 

 don, 1919.] Nature 104: 624. 1920. — A real contribution full of originality and of interesting 

 though bluff criticisms. The cautious philosopher would probably prefer greater elasticity 

 of the thesis. Omits reference to the important discoveries of Lower Devonian fossils in the 

 Rhynie-Chert and to question of transference of the tetral division in the course of descent 

 to a fresh position in the life cycle. — 0. A. Stevens.
