at Mr. Turner has observed of the European Orthotricha, 
= Null musci, quoad characteres genericos, tam abnormiter lu- 
dunt, et tam agre definiuntur*,” may with equal propriety be 
said of their affinities from the tropics. Hitherto I had in vain 
searched among those which bore the greatest natural affinity 
with the genus Fgeia ts of Bridel and Schwaegrichen, for a 
peristome > of that s ucture. In the present instance I have met 
with it, and such as prea in every essential particular with the 
figure in the Supplement to Hedwig’s Spec. Musc. Yet the 
plant itself bears such a resemblance to Ortholrichum longifo- 
lium, already figured in this work (Tas. XLIV.), that I kn ow of 
scarcely any other character but the peristome, by which it can 
be essentially distinguished.
