10 ERNST ANTEVS, LEPIDOPTERIS OTTONIS (GÖPP.) SCHIMP. AND ANTHOLITHUS ZEILLERI NATH. 
L. Ottomis is known from several localities in Scania, and occurs in great numbers 
in some strata. At Bosarp it even almost entirely alone forms a layer, which is 
comparable with the ”Blätterkohle” of Bothodendron in Tula, Russia. Besides at 
Bosarp it occurs very frequently in the plant-bearing strata « and 4 at Bjuf and 
the layer 4 at Billesholm. Other occurrences are Bjuf 1 and 3, Skromberga the 
lower seam, Stabbarp 1 to 3, Höganäs ”the lower”, and Hyllinge. The zones in which 
it is represented are thus those with Dictyophyllum exile, Camptopteris spiralis, and 
Lepidopteris Ottonis; and in the last-mentioned zone — plant-bearing layer 4 — it is 
met with most frequently. 
Genus Antholithus LinséÉ. 
Antholithus, LiNNÉ 1768, p. 172. 
The name of Antholithus was formed by LINNÉ in order to indicate ”Phytoli- 
thus floris', and was readopted by NATHORST (1908, p. 23) in its original sense, as 
a collective name of fossil flowers in general.

Since Professor NATHORST some years ago described the male reproductive 
organ AÅntholithus Zewlleri, it has for several reasons proved desirable to undertake 
a renewed examination of the same, especially with regard to the cuticle, and also 
to go through the existing material of ”Blätterkohle” from Bosarp, where it was 
expected to be found. This ”Blätterkohle” has entirely the same appearance as that 
which Bothodendron forms in Tula in Russia, and consists for the most part of cu- 
ticles of Lepidopteris Ottonis. In order to soften the rather firm and hard cakes, I 
boiled them with soda, a procedure which proved to be a very good one, as after 
this the washing was easily done. 
What immediately struck me on doing the washing, was the extraordinary 
uniformity of the layer. In thera ther large amount of material I went through I found, 
besides fragments of Lepidopteris Ottonis — which, as just mentioned, constituted the 
great bulk — several stalks (fronds?) of an undeterminable plant, some specimens of 
Antholithus Zeilleri and a great many free pollen-sacks of this latter, about ten seeds, 
one or two segments of a cycadean frond, and some animal remains. Everything was 
small and broken, and there were seldom even entire pinnae.
