An outgrowth of the work for nearly a generation, now, con- 

 ducted in connection with the laboratories of the Fish Commission 

 and the Marine Biological Laboratory. 



The botanical section of the first volume comprises pages 443 

 to 544, inclusive, with nos. 228 to 274 inclusive of a series of distri- 

 butional Charts of the waters of Vineyard Sound and ßuzzard's 

 Bay; and consists of chapters devoted to an introduction, an ana- 

 lysis of factors affecting the local distribution of algae, an analysis 

 of characteristic algal associations and formations, a report on the 

 algae of one harbor reef, "Spindle Rocks", and an account of the 

 distribution of algae in the deeper waters of Buzzards Bay and 

 Vineyard Sound. 



The botanical section of the second volume includes pages 795 

 to 833 inclusive, devoted to a catalogue of the marine flora of the 

 region, — limited to algae except for a note on the distribution of 

 Zostera in the deeper waters. Trelease.

Several small collections of marine algae brought together from 

 Lower California, Mexico, afford a basis for the present paper, 

 in which 27 species are enumerated. The following are described 

 as new: Dictyota Vivesii Howe, Scindia latifrons Howe, Anatheca 

 dichotoma Howe, Gracilaria Vivesii Howe, Fnuchea Sefferi Howe, 

 Fauchea (?) tnollis Howe, Halytnenia actinophysa Howe. and Clado- 

 phora MacDougalii Howe. These are all illustrated. One new "com- 

 bination" also appears: Codium decorticatum (Woodw.) Howe {Viva 

 decorticata Woodw.) Maxon. 



Griggs, R. F., The Development and Cytology oi Rhodo- 

 chytrium. (Botanical Gazette. LIII. p. 127—173. 1912.) 



After a cytological study of the life histor5^ Griggs concludes 

 that, in spite of some superficial resemblances, Rhodochytrium is 

 not related to any known Archimj^cete, but rather to the Protococ- 

 coideae through Phyllobium. Cytological resemblances between 

 Rhodochytrium and Synchytrium suggest that Synchytrium also was 

 derived from protococcoid ancestors.
