We owe two specimens, Fri 82- 1 and 92- 1 (the latter consisting of two pieces) to Prof. FRICKE ,
which he has collected with his submersible " Geo" 9 1 and 97 01 deep resp. Both are foliaceous fragments
of bigger specimens with encrusting bases.
In the outer lobe-shaped part of Fri 82- 1 collines are quite distinct, but in the middle part they are
only feebly developed. 0 radiating ridges are present. The corallites are very small and superficial, often
elliptical and in rows parallel to the margin. Septocostae are equal, straight, with granulated , rounded
margins, about 20 to 25 in 5 mm.
In Fri 92- 1 the collines are inconspicuous. Corallites are in short rows. Columella in elliptical corallites
mostly elongated.
Another sample, NS 4948, is only a small fragment of a foliaceous specimen. The collines are very
distinct so that the piece resembles L. mycetoseroides, but intersecting ridges are not present.
A second specimen which resembles L. mycetoseroides, Sa 95, is part of a plate-like corallum and is
comparatively thick. But we think it belongs to L. tenuis despite its conspicuous collines.

We have only one specimen which we owe to Prof. FRICKE, who has obtained it by diving with his
submersible " Geo" to a depth of 95 m. It is only a fragment , foliaceous and very thin. The corallites are
circular with raised rims and directed upwards, diameter 2 to 3 mm ; irregularly scattered or in short concentric
rows. No collines present. Septocostae equal, usually straight, with delicately granulated but
acute margins, about 25 in 5 mm. Columella well developed.
