S12 General Notes. ; [ April, 
George Murray, presented a paper bearing the title given above. 
The following summary is furnished to the NAruRALIsT, by the 
authors of the paper: 
ductive cells which are produced without any previous act of im- 
are pointed out, and it is proposed to restore the term spore to 
what has been in the main hitherto its ordinary signification, viz.: 
any cell produced by ordinary processes of vegetation and not by a 
union of sexual elements, which becomes detached for the purpose 
of direct vegetative reproduction, The spore may be the result 
of ordinary cell-division or of free cell formation. In certain 
cases (zoospores) its first stage is that of a naked mass of pro- 
toplasm ; in rare instances it is multicellular, breaking up into a 
number of cells (polyspores, composed of merispores, or breaking 
up into sporidia). Throughout thallophytes the term is used in 
the form of one of numerous compounds expressive of the special 
character of the organ in the class in question. Thus, in the 
Protophyta and Mucorini we have chlamydospores; in the 
Myxomycetes, sporangiospores; in the Peronosporez, conidio- 
spores; in the Saprolegniee, Odphycez, and some Zygophycee, 
zoospores ; in the Uredinez, teleutospores, zcidiospores, uredo- 
spores, and sporidia ; in the Basidiomycetes, basidiospores ; in the 
Ascomycetes (including Lichenes), conidiospores, stylospores, as- 
cospores, polyspores, and merispores; in the Hydrodictyea, mega- 
spores; in the Desmidice, auxospores; in the Volvocinez and 
Mesocarpee, parthenospores; in the Siphonez and Botrydice, 
hypnospores ; in the CEdogoniacez, androspores; in the Floridee, 
tetraspores and octospores. The cell in which the spores are 
formed is in all cases a sporangium 
In the terminology of the male fecundating organs very little 
change is necessary. The cell or more complicated structure in 
which the male element is formed is uniformly termed an anther- 
idium, the ciliated fecundating bodies, antherzoids (in preference 
to “‘spermatozoids.”) In the Florideze and Lichenes, the fecunda- 
ting bodies are destitute of vibratile cilia; in the former case they 
are still usually termed “ antherozoids,” in the latter “ spermatia,” 
and their receptacles ‘‘spermogonia.” In order to mark the dif- 
ference in structure from true antherozoids, it is proposed to 
designate these motionless bod:es in both cases pollinoids; the 
erm “spermogonium” is altogether unnecessary, the organ 
being a true antheridium. 
A satisfactory terminology of the female reproductive organs 
presents greater difficulties. The limits placed to the use of the 
term spore and its compounds require the abandonment of 
“odspore ” for the fertilized odsphere in its encysted stage anterior
