*CHOREONEMA, Schmitz. 
Ch. Thureti, Schmitz. (Melobesia Thureti, Born.) 
Common all round the coast, growing on Corallinu officinalis, 
C. squamata, OC. rubens. This species was for a long time regarded 
as an abnormal fruit of C. officinals. 
MELOBESIA, Lamx. 
M. confervoides (Lithocystis Allmanni, Phye. Brit.) 
Malahide, county Dublin (Phye. Brit.); Farrihy Bay, county 
Clare; Helvick Point, county Waterford.’ 
We are not altogether satisfied as to the independence of this 
species, in the absence of reproductive organs. 
*M. corticiformis, Kitz. 
Common all round the coast, on Furcellaria fastigiata, Lamx. 
M. membranacea, Lamx. 
Rosanoff (“ Recherches anatomiques s. 1. Mélobésiées”’) states 
that this species is not at allas common as recorded. There is danger 
of confusing it with If. Lejolisii, Rosan., and I. farinosa, Lamx. 
In the 8.W. on Cystoseira. General (?). 
MM. farinosa, Lamx. 
Roundstone, and other points in the West of Ireland; Helvick 
Point. Probably generally distributed, growing on Zostera. 
[IL. verrucata, Lamx. | 
In answer to our inquiries, M. le Prof. Le Jolis wrote :—“T 
do not possess any specimens of the enigmatic I. verrucata, Lamx., 
and my opinion is that such a name should be suppressed. 
Rosanoff, a very clever and conscientious botanist, who, at my 
request, undertook here the study of Melobesieze, went to Caen in 
order to investigate the type specimens of Lamouroux’s herbarium, 
and ascertained that the specimen labelled J/. verrucata by 
Lamouroux, is nothing but JL pustulata.”
