Thisis a small and obscure species, having no striking character 
by which it may be readily distinguished from its numerous con~ 
genérs, yet not exactly agreeing with any one hitherto published. 
It is probably a Leskea, judging at least from its erect capsule 
which is so common in that genus ;_ but although my specimens 
possess capsules with peristomes, yet this part is so minute and 
so extremely fragile that I am unable to satisfy myself as to the 
true structure of its inner teeth.
