original figure of this plant, in " Flora Danica," re- 
presents them as placed in pairs. 
5. S. tenioe. In very recent specimens there appear to 
be 8 equidistant, bigeminated teeth ; but the pro- 
cess of drying (without pressure) produces a divi- 
sion into 16, geminating in pairs, each with a lon- 
gitudinal line, denoting simple gemination ; this 
line is somewhat obscure, from the thick substance, 
and consequent greater opacity, of the teeth. The 
figures in Weber and Mohe, Tasch, t. 7. f. 2., 
and in " English Botany,'' t. are correct. 
6. S. octoUepharum. From Dr Hooker's figure and 
description in " Musci Exotici," there exists in this 
species the proper number of primary teeth. They 
are, however, permanently compounded into 8, 
each of which is marked by three longitudinal lines. 
Our own specimens have lost their peristomes ; but 
from Beown (in the Appendix to Parry's first 
Voyage, p. ccc) placing it in the genus Splach- 
num, " dentibus reflexilibus," we are inclined to do 
the same, as that gentleman, the discoverer of the 
species, must have had more numerous opportuni- 
ties of examination than any other. We suspect 
our friend Dr Hooker has inadvertently transposed 
the words siccitate and madore, in describing the 
teeth ; " siccitate (madore ?) incurvis, madore (sic- 
citate ?) erectis vel etiam reflexis." 
T. S. Magellanicum. Of this plant, Bridel says it pos- 
sesses 1 6 geminate teeth ; but from his remaining 
description, we suspect he intended 16 geminating, 
or, in other words, 8 geminated ones. We have 
ascertained that there are 16, resulting from the 8 
teeth having divided : they are geminating in pairs,, 
each tooth having a longitudinal line, w hich seem&
