Carrington. It was discovered by Mr. John Whitehead 
during a botanical excursion to Ben Nevis, July, 1875. It 
has not yet been described, but is near in form to Junger- 
mannia StarJdi, and probably may have been overlooked 
for that species. Dr. Carrington thinks it may be new iu 
science, but he confirms Mr. Whitehead’s surmise that it is 
new to Britain, and it will consequently appear in the ap- 
pendix to Dr. Carrington’s work on British Hepaticae. It 
grows in moderate sized patches on the sloping banks of the 
mountain. Neither male nor female flowers have yet been 
found. 
Professor W. Boyd Dawkins, F.K.S., exhibited a series of 
specimens which he obtained in September, 1875, from the 
inner side of the barrier reef at Honolulu, ^together with 
photographs. At that point of examination the reef was 
formed of irregular nodular limestones composed in part of 
corals, millepores, and perfect shells, but mainly of fragments 
so broken up and altered by the action of carbonic acid that 
the original structure was almost lost. The fine calcareous 
sediment forming the bottom of the lagoon, and covering 
the shore up to the very edge of the lof ty palms was analo- 
gous in every respect to that which composes the oolitic 
limestones, and especially the Bath or great oolite. In the 
deposits on the inner side of the reef, as well as in the 
limestones above mentioned, corals were equally distributed. 
The masses of coralline limestone were traversed by Ser- 
pulse, just as in the case of the Coral Crag. 
The few shells which he happened to find were as
