 chens. [A saprophytic Oscillatoria in the intestine of the guinea pig.] Centralbl. Bakt. II. 

 Abt. 50: 356- 3G7. 1920. — The author, while searching for Trichomonas in the caecum of 

 guinea pigs, accidentally discovered an alga which after careful study was found to be an 

 Oscilla aria. Botanically the important point of interest is the nutrition of this alga which, 

 living in total darkness, has become colorless and can no longer assimilate CO2. It is prob- 

 able that nutrition takes place purely through diffusion of organic materials in solution. The 

 author, a zoologist, calls on the botanists for further investigations. — Anthony Berg.

 Madrid, 1919.— Aside from lists and short treatments in general descriptive works there 

 has hitherto been no publication of much value to the student of the hepatics of Spain and 

 Portugal. The present work fully supplies this need. The general introduction is followed 

 by a detailed discussion of numerous morphological topics and by an account of the ecology 

 and geographical distribution of the Hepaticae, in which emphasis is laid on their relation to 

 substratum, humidity, latitude, and temperature. In the taxonomic portion of the volume, 

 which occupies nearly 600 pages, 329 species are described and figured or at least critically 

 discussed, many of these species being still unknow^n on the Iberian Peninsula. The book in 

 fact is a manual of the hepatics of all southwestern Europe. In classification and nomen- 

 clature Schiffner's treatment in the Engler and Prantl Pflanzenfamilien is usually followed, 

 but the author has found it advisable to propose the following new specific combinations: 

 Calycularia Flotowiana (Nees), Haplozia Muelleriana (Schiffn.), Haploziaparoica (Schiffn.), 

 and Haplozia subelliptica (Lindb.). — 0. E. Jennings.

 South Africa 8: 179-224. PI. 11, 12. 1920.— A long series of South African mosses is enumer- 

 ated, most of which were collected by H. A. Wager, T. R. Sim, J. Henderson, D. B. Hen- 

 derson, or M. Henderson. Each species is accompanied by full data regarding localities 

 and, in many cases, by critical notes. In several instances the identity of South African 

 species with those occurring in north temperate regions is established, and keys to the South 

 African species are given under Bryum and Lindbergia. The following new species are de- 

 scribed and figured, Dixon being the authority except where otherwise noted: Brachythecium 

 afro-albicans, B. pinnatum, Bryum pumili-roseum, Dicranella Symonsii, Didymodon ajro- 

 rubellus Broth. & Wager, D. Pottsii, Ditrichum spirale, Entodon cymbifolius Wager & Dixon, 

 Erpodium dzs^tc/ium Wager & Dixon, E. transvaaliense Broth. & Wager, Fissidens papillifolius, 

 Glyphomitrium marginatum Wager & Dixon, Gymnostomum Bewsii Sim, Isopterygium bra- 

 chycarpum, Lindbergia viridis, Microthamnium ctenidioides, Plagiothecium Hendersonii, 

 Psilopilum afro-laevigatum, Ps. Wageri Broth., Sciaromium capense, Tortula trachyneura, 

 and Zygodon Simii. The following new specific combinations are likewise made: Anomo- 

 bryum promontorii (C. M.), Brachymenium campylotrichum (C. M.), and Gymnostomum gra- 

 cile (Wager). — E. M. Doidge.
