No.416.] REVIEWS OF RECENT LITERATURE. 689 
The descriptions are sufficiently full, and appear to be accurate , 
occasionally a word is used in a sense that might be misleading, as 
on p. 21, where certain desmids are said to occur *en parasites," 
on Sphagnum, etc. Full references are given to French authors, 
and a considerable number to foreign works, but the English lan- 
guage-seems to offer great difficulties to M. Comére, as it has to 
many others of his nation. There are many references to Wolle's 
Desmids of the United States, and this work, with three papers pub- 
lished in the Zorrey Bulletin, appears in the bibliography. It is fair 
to assume that M. Comére must have seen the book, but both in 
references and bibliography the name is * Woole." Quite curiously, 
at p. 98 there is a reference to another Torrey Bulletin article, 
which does not appear in the bibliography, and in this one place the 
name is properly spelled, * Wolle." “ Dysphynctium TÀwatesiz," with 
synonym “ Calocylindrus Twatesii,” at p. 92, and * Twaites," p. 130, 
represent three attempts on the name of a well-known botanist. 
bs Barcker in Quartely Journal, p. 208,” is an interesting combina- 
tion. A certain amount of carelessness in proofreading is noticeable 
here and there: in the bibliography Reinsch is followed by a period, 
as if an abbreviation, while Schaarschm has no period, though it 
represents Schaarschmidt. Sutarastrum, Closterium monoliferum are 
similar cases. But let him that never overlooked an error ona proof- 
sheet cast the first stone at M. Comére. 
The work makes no innovations and does not claim to add 
largely to previous knowledge, but it puts in small compass, and in 
shape convenient for the student, what otherwise would have cost 
him much time and trouble. Any work doing this is valuable. The 
nomenclature is eminently conservative; no new species is proposed, 
nor 1s any one transferred from one genus to another; the author 
must have nobly resisted’ the temptation to attach his name to 
Something,
