broad and short. The stem nearly twice as long as the
rachis, and expanding, gradually, up towards the rachis.
The ventral surf ape furnished with a deep mesial furrow,
through whose bottom the calcareous axis becomes visible,
and on whose margins, there are 2—3 series of
protuberant zooids. On the dorsal surface, there is a less deep
and shorter furrow. The polyps are large, and arc
situated in 3 somewhat irregular series. The rachis light
brownish-yellow, tending a little to violet. The stem
whity-yellow. The polyps pale violet.
