Mycetozoa. 



Synopsis of the Orders, Genera, and Species of Mycetozoa.* — Since 

 the publication of the British Museum Catalogue in 1894, a considerable 

 number of genera and species have been recorded, and A. and G. Lister 

 have prepared a new synopsis, including all the new forms that have 

 come under their own observation. A bibliography is appended of 

 publications bearing on the subject. 



Lichens. 



(By A. LoEEAiN Smith.) 



Lichen Distribution in the Santa Cruz Peninsula.f — The Cali- 

 fornian territory included in this survey is about ninety miles long and 

 thirty-five broad at the widest part. It ranges from sea level to a height 

 of 'M[)i] feet, and presents a great variety of situation, maritime and 

 alpine, rock and forest. It is found that alpine temperate and tropical 

 species are all mingled, while some genera are remarkable by their 

 absence. No species of Graphis or Stereocaulon has been found, and no 

 specimen of CJadonia rangiferina. The writer, Albert W. C. T. Herre, 

 gives lists of the most conspicuous forms found in the different biological 

 areas. He has in his herbarium 200 named species and sub-species from 

 the Santa Cruz region, with perhaps a hundred more not yet satisfactorily 

 determined. 



Notes on Cladonia.| — Bruce Fink has selected Cladonia degemrans 

 and some allied species for examination, and reports on the difficulty in 

 determining the different forms and of referring the many varieties to 

 their proper affinities. He remarks that in the present state of knowledge 

 of the genus, " it is impossible to place the Gladonias all in any probable 

 continuous genetic series."
