This curious plant was gathered in small quantity on cliffs near 
_ the Granges d’Astos ; the appearance was that of £, ciliata, but 
_ the base of the calyptra was quite entire, or rarely with a few 
__ inconspicuous fragments of fringe. An Encalypta ciliata with à 
 non-ciliate calyptra was such a bouleversement of one's ideas of 
.  propriety even in such a plastic genus, that we tried for some 
_ time to fit the plant to some other species, but without success, 
and M. Thériot ultimately suggesled the foundation of a new 
variety upon the specimen. Recently however in studying Dalla 
Torre et von Sarnthein's Moose von Tirol, etc., I was struck by a 
_ reference lo à new variety subciliata of E. ciliata published . 
 Warnstorf (Miscellen aus der europäischen Moosflora, 1899). I 
… have not seen a specimen of this variety, but a reference to the 
‘ original description leaves little doubt as to the practical identity 
of our Pyrenean moss with the Tirolese plant described by Warns-
