its silvery lustre when dried. Looking at all these previous 
authorities, it is surprising to find Professor Smith applying 
Agardh's name of flabellata to the cuneate variety, and 
uniting in the synonymy, the L, radians of Kiitz., which is 
the true L. splendida of Greville, with the species described 
byAg. in the ^ Conspectus,^ p. 41, and the ExiUaria flabellata 
of Greville, which are identical with the form to which he 
gives the name of splendida. There appears to be the same 
confusion in the localities given, as the Torbay specimen of 
Mrs. Griffiths, and those of Salcombe of Mr. Ralfs, have the 
linear- cuneate form, which is the imQ flabellata j Ag., not the 
L. splendida of Smith.

This form, whether it be a different species, or merely a 
variety, does not seem to be so well known as that previously 
described, but it appears to have been separated by all writers 
on the genus since the time of Agardh from its smaller size 
and the decidedly cuneate form of its frustules. Dr. Greville, 
in the ^ Brit. Flor.,^ p. 408, says it is ^' nearly allied to flabeU 
lata, but smaller and less divided, and frustules more broadly 
wedge-shaped ; tufts two or three lines in height." Captain 
Carmichael describes the frustules as having terminali latis- 
simi," and notices the peculiar arrangement of the endochrome 
as having the appearance of " bars or ocelli," which occurs in 
some of the gatherings I have, and is shown in tab. xxvi, 
fig. 234 of the ' Synopsis.-* Kiitz. describes L. radians as 
with frustules "cuneatis, basi acutis, apice latioribus." Mr. 
Ralfs copies Professor Smith, but is doubtful if both ought 
not to be referred to one species ; and yet, with these cha- 
racters by the earliest observers of the form, Professor Smith 
has applied the name of splendida to the linear- cuneate and
