series of nudibranch radulae led the exhibitor to conclude that such 
changes, in so far as they affect the dental formula or number of teeth, 
were common to the whole sub-order Nudibranchiata.. and in each species 
continued to take place throughout the life of the animal. 
1). M'Ardle exhibited a germinated spore of Tetraphis pelliicida with 
protonema, showing the peculiar frondiform leaves which appear at the 
lirst development of the moss stem ; they arc ligulate or ovatc-spathulate 
in shape from a narrow base ; in this species they disappear before the 
development of the moss stem is completed and are rarely to be seen. 
In the other native species T. Browniannm these curious leaves are per- 
sistent, and form a tuft of radical frondiform leaves, which are sometimes 
divided like the fronds of the Forked Spleenwort. A North American 
species T. geniculata ditlers from the others in the absence of the gemmae, 
and above all in the geniculate pedicel. In T. rcpanda which is found in 
France and elsewhere on the Continent the frondiform leaves are replaced 
by minute tlagelliform shoots bearing very minute nerveless leaves. 
The specimens exhibited were collected recently on a peaty bank in the 
Glen of the Downs, Co. Wicklow. 
NOTES. 
BOTANY 
Stachys Betonica, etc., in West Cork. 
Included in a small collection of plants sent me by a friend from Castle- 
town Berehaven was a specimen of Stachys Betonica gathered near Garinish 
Point, about ten miles west of the village. It grew on a heathery slope 
between the road and the sea near the White Strand, and was only noticed 
in one spot. This is a very interesting restc ration to the County Cork 
flora. It was recorded by Drummond so long ago as 18 19 as growing 
" in the baronies of Bere and Imokilly, Cork," but has been quite lost 
sight of in the county for nearly a hundred years. Among other plants 
sent me from this locality were Spiranthes antuninalis, gathered near the 
roadside a little west of White Ball Head ; Verbena in several localities 
about the village ; and Wahlenbergia found near the village of Eyeries 
on the Kenmare Bay side of the Slieve Miskish mountains, about four 
miles north west of Berehaven. The Stachys, Spiranthes and Verbena 
were found by Mrs. Crookshank, the Wahlenbergia by Miss Mary Crook- 
shank. Now that Drummond's old record for the Barony of Bere has 
been proved correct, there is every reason to hope that it ^^^ll be refound 
in the Barony of Imokilly also, which would restore this plant to the East 
as well as to the West Cork divisions of Praeger's " Irish Topographical 
Botany."
