closely beset with slender, many times forked, lateral ramuli. These spread 
towards all sides, are from } to 1} inches long, of the thickness of bristles, 
divaricated, often intertwined, and forming a mop-like head. All the axils 
are remarkably wide and obtuse; the apices obtuse. No fructification has 
been observed. The colour is a very dark brown-red, becoming almost cho- 
colate-colour in the dry state. Substance very soft, highly elastic, and lu- 
bricous. In drying, the frond most closely adheres to paper. 
ARR RRR eee 
If future observation on the fruit (still unknown) of this cu- 
rious Alga should induce any one to remove it generically from 
Nemalion, where, for want of a better position, I now place it, 
I suggest that the genus to be founded might appropriately bear 
the name of Wiggia, in honour of Mr. Lilly Wigg, “the friend 
and original instructor in this department of botany”’ of Dawson 
Turner, not merely because Mr. Wige’s memory deserves to be 
held in grateful remembrance by algologists, but because this 
plant is really very like a well-curled full-bottomed wig/ Joking 
apart, I have been puzzled to know where to place this species. 
The original reference to Vemastoma I have long discarded. My 
inducement now to refer it to Vemalion, instead of to Helmin- 
thocladia, arises from the tendency to dichotomous ramification, 
here carried to an extreme excess. But if the frond only assimi- 
lated carbonate of lime in its tissues, the structure is sufficiently 
near that of Zzagora to allow of a place in that genus. On the 
whole, I incline to think that the /rwi/. when found, may show 
that this puzzling customer is swz generis.
