_ Micrasterias foliacea Bail. (Bern. p. 133-135, f. 220-223). 
M. Bernard’s figures are erroneous, and his remarks absurd, in 
view of the accurate figures and complete description of the apical 
attachment of the cells given by Johnson in Bot. Gazette, xix. 
1894, p. 56-58, t. 6, f. 1-4. : 
M. Crux-Melitensis (Ehrenb.) Hass. var. bogoriense Bern. 
(p. 139, f. 233) is identical with the form described by Turner in 
1893 as M. radians. 
Staurastrum dejectum Bréb. vay. patens (Bern. p. 143, f. 241) 
= S. dejectum, type. 
S. bidentatum Borge var. simplex Borge forma trigona Wild. 
(Bern. p. 146, f. 253-256). This is most probably a form of 
S. striolatum (Nag.) Arch. 
S. javanicum (Nordst.) Turn. var. maximum Bern. (p. 151, 
f. 264-267) = a form of S. Manfeldtii Delp. 
S. proboscideum “ (Bail.) Arch.” (Bern. p. 152, f. 268, 269) — 
S. Sonthallianum Turn. 
S. margaritaceum (Ehrenb.) Menegh. var. hirtum Nordst. (Bern. 
p. 154, f. 275, 276). This is not a form of S. margaritaceum. 
Kirchneriella lunaris (Kirchn.) Moeb. (Bern. p. 178, f. 392-397) 
= K. subsolitaria G. 8. West (1907). 
Scenedesmus obliquus forma intermedius Bern. (p. 182, f. 417- 
S. denticulatus Lagerh. var. diengianus Bern. (p. 185, f. 448) 
= 8. denticulatus var. linearis Hansg. 
Polyedrium requlare ‘*(Kg.) Chod.” (Bern. p. 192, f. 471, 472, 
474) — Tetraédron trigonum. 
nected with the literature of the subject prevented him from giving 
his attention to the Javanese Diatoms. One cannot help being 
sorry that he did not arrive at the same conclusion concerning the 
other groups of Algw ! 
It is both astonishing and distressing that a paper displaying 
such ignorance of the systematics of the groups dealt with should 
be allowed to emanate from an institution of the standing of the 
Botanical Gardens at Buitenzorg.
