What Mr. Turner has observed of the European Orthotricha, 
dint, et tam egre 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 Sclotheimia of Bridel and Schwaegrichen, for a 
peristome of that structure. In the present instance I have met 
with it, and such as accords in every essential particular with the 
figure in the Supplement to Hedwig’s Spec. Musc. Yet the 
plant itself bears such a resemblance to Orthotrichum longifo- 
tium, already figured in this work (Tas. XLIV.), that I know of 
scarcely any other character but the peristome, by which it can 
be essentially distinguished.
