I . — New Diatoms from Honduras. Described by Herr 
A. Grunow. With Notes by F. Kitton, Hon. F.R.M.S. 
( Taken as read before the Royal Microscopical Society, 1877.) 
Plates CXCIII., CXCIY., CXCV., and CXCVI. 
In the year 1867, a paper entitled “ Diatomeen auf Sargassum von 
Honduras gesammelt von L. Lindig, untersucbt von A. Grunow,” 
appeared in Hedwigia. Herr Grunow has very kindly sent me 
for publication in this Journal, extracts and supplement (translated 
into English), with the request that I would see it through the 
press, and also correct any errors in the translation (from which 
by the way it is singularly free) ; he has also added some valuable 
remarks on allied species and genera. The figures are from his 
own drawings and have not been previously published. 
(The species which are now described for the first time are 
marked “ n. sp.”) 
Licmophora. 
L. Remulus Grun. L. a latere primario anguste cuneate, 
valvarum parte inferiore plus minus elongata, anguste lineari 
stipitiformi, subito in laminam oblongam, vel lineari oblongam, 
apice rotundatum dilatata, linea media in parte superiore con- 
spicua, striis transversis tenuissimis 33-31 in - 01 mm.* Longit. 
•05- - 24 mm., latit. valvm partis superioris ‘ 01— * 013 mm., 
latit. stipitis '0015- '002 mm. Tab. CXCIII., Fig. 1, a, b. 
1 have a similar Licmophora from the Samoa Islands, in which 
the inferior part of the valve does not widen so abruptly into the 
upper portion; the strife are also coarser (27 in '01 mm.). I 
have named it L. Remus, but I am doubtful if it be sufficiently 
distinct from L. Remulus. Both species have short gelatinous 
stipes, and would therefore belong to the genus Podosphenia or 
Rhipidophora, Kutz., but as the length of the gelatinous stipes is 
of no generic value, these genera must be united to Licmophora. 
(See Hedwigia, l. c.) 
* About 84 in "001 of an inch. Two and a half times the number of strife 
in - 01 of a mm. very nearly agrees with the number in -001 of an English inch.
