longer. ae 
Peristome delicate and fugacious : outer teeth equal to the 4 
inner, marked with 16-19 trabeculæ ; inner peristome reddish, — 
the processes slender (only one third the breadth of the inter E: 
mediate spaces) obscurely marked with a medial line, united - 
into a narrow basal membrane, through which the medial lines — 
distinctly produced. Annulus none. a 
In L. polycarpa the teeth are more numerously trabeculate, : 
and traversed by a medial line; the processes of the innt - 
peristome are pale-coloured, firmer and broader than in D. 
pulvinata (very nearly as broad as the intermediate spaces) 
marked with a very distinct medial line, not unfrequently 
with rudimentary cilia between them; the membrane into 
which they are united twice as broad as that of L. pulvinata 
and more widely areolated ; central line of the processes not 
continued down into the membrane. (In L. polycarpa he 
outer peristome is most fugacious, in L, pulvinata the inner

the outer peristome fallen away, while the inner rema 
quite perfect)* Annulus present, consisting of a Si

Operculum pale yellow, hemispherical below, tapering UP"

In L. polycarpa the operculum is red at the base and apes

* The explanation of this appears to be that in L. pulvinata the outer 
teeth are incurved from the very base, and after the emission of the 5° 
so strongly so as to cause the destruction of the inner peristome, W ul V 
themselves remain uninjured; but in L. polycarpa the outer tee 
recurved at the base then bent upwards and incurved into an a 
circular form, and they finally break off at the base, leaving the 
peristome quite entire,
