brane. Massart, on the protoplasm of the Schizophytes, concludes that the 

 central body» even when it occurs, is not the homologue of a nucleus; nor is 

 the " couche corticale" the homologue of a plastid. He regards the Schizo- 

 phyceae as derived from the bacteria, but the group as a whole as nowise 

 related to any other organisms. In his last paper, Massart introduces a 

 deluge of new terms sufficient alone to form a supplement to any up-to-date 

 dictionary. The analysis of the subject is clear, and in large part logically 

 carried through; and a clean-cut vocabulary is prerequisite to clean-cut think- 

 ing, still more to lucid expression. Codifying such a terminology is an 

 unqualified service to those who use it, as Czapek's forerunner has well proven, 

 but every uninitiate will want to go armed with a'* Nomenclator Massartianus" 

 before "geanisopachynosis," "tonesagogic," " cathaptotropic," and the scores 

 more like them become familiar terms. — E. B. Copeland. 



NOTES FOR STUDENTS. 



Nine species of the Corallinae (verae) from Port Renfrew are described 

 :and figured by K. Yendo.'^ Three of these are new species, viz., Chcilo- 

 sporum MacMillani^ Corallina vancoiiveriensis, and Corallina aadeaia.

The new 0^67//c^/^^-z'^/^^^^^a/^/(^^^ is a colorless sulphur-bearing organism 

 described by Arzichowsky,'^ and considered by him as a transition between 

 Oscillatoria and Beggiatoa. The sulphur grains are very small and he 

 close to the cell wall. The account of this interesting form is to be found 

 among the descriptions of several species of Beggiatoa. It deserves better 

 treatment in a language and a journal that will reach more botanists. The 

 paper is written in Russian, with a very short and unsatisfactory r^sum^ in 



German. — B, M. Davis. 



Pterygophora cahfornica is described and figured by MacMillan,^ 

 who presents some interesting observations on its anatomy and development. 

 Pterygophora is a surge plant growing below the zone of Lessonia and above 

 that of Nereocystis. The general morphology is closest to Alaria, but the 

 distribution of the sori found in the lateral pinnae, together with the "dispo- 

 sition of cuticular caps in the paraphyses," suggest Lessonia. Some of the 

 plants are very large, being ten feet long with stalks three inches in diameter.
