p- 347. There is really no other difference, and the foliage and 
all essential characters of the fruit are so exactly the same in 
both groups that it seems unnatural to separate them. More- 
over, although the calyptra is not veiled by the adherent 
involucre, it is in most species bristled over with the persistent 
sterile styles ; so that the name Letomitra can hardly be called 
appropriate.

§ 1. Cephaloziee. 
Genus 7. CepHatozia, Dum. 
In Cephalozia proper there is but one species, found in small 
quantity creeping over an Anewra at the Grande Souffri¢re of 
Dominica, but in a good state of fruit, which has enabled me to 
describe it. It had already been found in Cuba by Wright, and 
named by Gottsche Jungermannia Wrighti. It is interesting 
from being a close ally of the most beautiful of our British 
Cephaloziea (C. curvifolia), from which it differs mainly in the 
presence of marginal teeth or spines, but has the same saccate 
asymmetrical base.
