280 MORPHOLOGY AND TAXONOMY, BRYOPHYTES [Box. Absts., Vol. X, 



of minute leafy hepatics with bilobed leaves. It is based on the old genera Dichiton, Cephalo- 

 ziella, and Prionolobus, but the author segregates from Cephaloziella the genera Lophoziella, 

 Evansia, and Protocephaloziella, all of which he had characterized in an earlier article. The 

 present work is divided into a general and a special part. In the former he discusses the 

 characters of the family and attaches especial importance to those drawn from the sporo- 

 phyte, such as the arrangement of cells in the pedicel and the histological features of the 

 capsule-valves. He shows also that the group is amply distinct from Cephalozia and its 

 allies, with which Cephaloziella and Prionolobus were previously associated. The 6 genera 

 which he recognizes he bases largely on characters derived from the gemmae and involucral 

 leaves, and he insists on the importance of definite morphological characters in distinguishing 

 the species. In the special part he gives detailed keys to the genera, species, subspecies, and 

 varieties of the entire world, assigning 1 species to Dichiton, 2 to Lophoziella, 3 to Prionolobus. 

 4 to Evansia, 1 to Protocephaloziella, and 55 to Cephaloziella. The following new species are 

 proposed, Douin being the authority unless otherwise noted: Cephaloziella alpina (Northern 

 Hemisphere), C. antarctica (antarctic region), C. arvernensis (France), C. Brinkmanni (North 

 America), C. cibulkensis (Bohemia and the Adriatic region), C. gallica (France), C. Holzingeri 

 (North America), C. hyalina (Florida), C. inaequiloba Schiffn. (Himalayas), C. Levieri 

 Schiffn. (Tasmania), C. norvegica (Norway), C. pentagona (Africa, Japan, and Oceanica), 

 C. Rappii (Florida), and C. Siephanii Schiffn. (Java). At least 2 of these species have already 

 been published without descriptions, but the list does not include several other species desig- 

 nated as new, owing to the fact that Douin has briefly characterized them in earlier works. 

 The following new subspecies are likewise proposed: C. glacialis (Europe) and C. Lorenziana 

 (U, S. A.) under C. alpina; C. turfacea (Austria) under C. rubella (Nees) Warnst.; C. carnu- 

 tensis (France), C. nigrimonasteriensis (France), and C. scabrifolia Douin & Schiffn. (U. S. A.) 

 under C. Starkii (Funck) Schiffn.; C. angustiloba (U. S. A.) and C. spinosa (Sweden) under 

 C. striatula (C. Jens.) Douin. There are in addition many new combinations, necessitated 

 by the transference of species or by their reduction to subspecific or varietal rank. In the 

 following list only the new specific combinations are given: C. arenaria (Steph.), C. capillaris 

 (Steph.), C. hirta (Steph.), C. Kiaeri (Aust.), C. minima (Aust.), C. patulifolia (Steph.), 

 C. Pearsoni (Spruce), C. Spegazziniana (Massal.), C. subbipartita (Massal.), C. sribtilis 

 (Lindenb. & Gottsche), C. Welwitchsii (Steph.), and Lophoziella rhizantha (Mont.). — .4. W.

 muscinees. [Experimental cultures of Fegatella conica and of some other bryophytes.] Compt. 

 Rend. Acad. Sci. Paris 172: 1521-1523. 1921. — This paper presents a continuation of studies 

 previously reported. Three forms of Fegatella conica were found growing in the greenhouse 

 under different environmental conditions. They maj^ be converted one into the other by 

 altering the conditions. — C. H. Farr.

 present installment contains keys to the acrocarpous genera from Tortula (pars) to Webera. 

 The whole moss flora of the Atlantic Islands is being covered. — E. B. Chamberlain. 



1841. Meylan, Ch. Nouvelles contributions a la fiore bryologique du Jura. [New con- 

 tributions to the moss flora of the Jura Mountains.] Rev. Bryologique 48: 1-5. 1921. — The 

 author records the results of his exploration in the Jura Mountains since 1919. Thirty 

 species of mosses are listed with full data regarding localities and, in several cases, with 

 critical observations. Of the species included, Pohlia pulchella (Hedw.) Lindb. represents 

 an addition to the Swiss flora, Eurhynchium Stokesii (Turn.) Br. & Sch. is definitely recorded 

 for the 1st time from Switzerland, and 4 others represent additions to the flora of the Jura 

 region. Under Thuidium abietinum (L.) Br. & Sch. a new variety paludosum is proposed 

 and Th. hystricosum Mitt, is reduced to varietal rank. — A. W. Evans.
