praecedente (Agassiz) ; etiam per montes Novaeboracenses. The 
first locality was Lake Superior, the second locality is not cited in 
the Manual, and we have seen no specimens except from the one 
referred to above and those collected in Idaho by J. B. Leiberg; 
the species seems to be very rarein America. Number 183 agrees 
with the description. given by Limpricht, and with European 
specimens, and is particularly noticeable for the broad, erose cilia, 
alternating with and nearly as broad as the teeth and often united 
by transverse bars. 
In Austin’s herbarium this species is confused with O. speci- 
osum, which also has smooth capsules, but they are longer and 
cylindric, not ovoid, and are more exserted ; the teeth are in pairs, 
not single, and the cilia are 8, not 16, and much narrower and 
tapering. An autograph specimen from T. P. James, collected at 
Errol Dam, N. H., is also'O. speciosum, labelled O. letocarpum, and 
he and Austin seem to have confused all their corresponcents, for 
there are specimens wrongly so labelled, from Macoun, collected 
at five Canadian localities, from Fowler in New Brunswick, and 
others, all of which prove to be O. speciosum. Macoun’s Canadian 
Mosses, No. 126, distributed as QO. /eiocarpum is, in our set all O. 
speciosum, as the catalogue cites it. Sullivant had the two species 
correctly separated, as autograph specimens sent to Dr. Torrey 
show, and in later years Austin corrected his mistake.

This species is very differently treated by the three European 
serials,* now in course of publication, and seems to be very 
variable, judging by the number of varieties described and the 
difference in the aspect of the specimens. 
It has a strongly ridged exserted capsule, with a short im- 
mersed seta, long, tapering neck, and the teeth reflexed when dry, 
united in pairs, (4) with eight erect cilia. But it varies from 
yellow to almost black, and in size from 1—5 cm.; also the capsule 
is either immersed or almost entirely exserted, cylindric oF 
urceolate with a flaring mouth, and the teeth are more or less 
trabeculate at apex. Venturi keeps it separate from O /as-
