The author reverts to the old names Stigeodonium and ^irogonium, 

 the generic name Protococcus is substituted for Pleurococcus, and 

 the genus Chlorococcum is now accej^ted as an independent one. The 

 merging of Endosp]i(Bra, Scotinosphcera, Chlorocystis^ tStoinafocItg- 

 irium, and CentrosphcBra in the genus Ghlorocliytrium is advocated, 

 a view with Avhich most algologists are likely to concur. Other 

 systematic points that call for notice are the inclasion of JProtoderma 

 in the Chietophoracese, of Vaucheria in the Siphonales, and of Bhaphi- 

 donema in the Ulotrichacese, all quite in accordance with modern views, 

 although Rhaphidonema would perhaps find a better place in the 

 Cha^tophoraceae. On the basis of Griffith's work Glancocystis is 

 retained among the Myxoi^hycese, but some will prefer to preserve an 

 open attitude of mind on this question until more is known about the 

 cytology of the species of Oocystis, with which there are undoubted 

 points of contact. We should have preferred to have seen the Volvo- 

 cales treated as an order separate from the Protococcales, although 

 that is a matter of opinion. Nor does it ap]:)ear desirable to separate 

 the Ulvales and Schizogoniales from the Ulotrichales. The classifi- 

 cation of the Heterokonta^ adopted is largely that suggested by 

 Pascher. 



At the end of each section there is a comprehensive bibliograj^hy, 

 including most of the literature of importance dealing witli the 

 different groups. Amongst papers which we think should have been 

 cited are Murray and AVhitting's on the Peridinea^, Senn's on Proto- 

 coccales, Heinricher's on Splice ropilea, and some of Comere's publi- 

 cations on algal ecology. 



I'he section on the occurrence and distribution of freshwater Algae 

 will be of great value to the student, since it is almost the first attempt 

 to classify Algae according to their habitat. From the ecological point 

 of view, one cannot help feeling that more might have been done in 

 the way of description of definite algal associations.

BOOK-NOTES, NEWS, etc. 



We have heard with deep regret of the death of Mrs. Talbot at 

 Degema, Southern Nigeria, on December 28th last. Headers of the 

 Journal will have become familiar with* the name from the descrip- 

 tions of new species published from time to time in its pages. During 

 the past eight years Mr. and Mrs. Talbot have sent at intervals to the 

 Department of Botany, British Museum, the results of their botanical 

 exploration in Southern Nigeria. Mr. Talbot's time has been much 

 taken up with his Government work, and the principal labour of 

 making the collections fell to Mrs. Talbot and her companion and 

 sister Miss Amaury. Mrs. Talbot also made an extensive series of 

 beautiful coloured sketches which with her notes on the plants have 

 been very helpful when w^orking out the collections. From 1909 to 

 1912, during the period of Mr. Talbot's Government service in the 

 Oban District, extensive collections were made in this rich botanical 

 area just west of the Cameroons. These were worked out in the
