Milne Edw. and J. Haime, Comptes rend. de l’Ac. des Sce., t. xxvii, p. 491, 1848. 
Corallum composite, massive, short, and increasing by fissiparity. Corad/ites having dis- 
tinct calicula, but united in linear series, which are cemented together laterally. The 
other characters as in the preceding genus.

37. Genus MycrropHyLiis. 
Milne Edw. and J. Haime, Comptes rend., t. xxvii, p. 491, 1848. 
Corallum massive, composed of corallites intimately united in series by their walls, 
which are very thin. xterior common walls \obulate, spinulous, and presenting but rudi- 
ments of an epitheca. Calicular grooves, very shallow. No columella, or only rudiments of 
one. Septa not numerous, scarcely exsert, strongly dentate, and confluent. Dissepiments 
vesicular, large, and abundant ; loculi closed almost to their top.

38. Genus KUNOMIA. 
Lamouroux, Exposit. Method. des Polypiers, p. 83, 1824. 
Corallum cespitose, fissiparous ; Coralliles segregate, tall, cylindroid. Calices almost 
circular. Columella rudimentary. Septa not very numerous. /Va//s covered with a complete 
membraniform epitheca, strongly striated transversely.

Corallum fasciculate, cespitose, and dichotomous. Cora/lites very long and segregate. 
Calices not very deep. Columella rudimentary or not existing. Sep/a thin, numerous, 
crowded, and armed with apical teeth, the size of which increases from the margin towards 
the centre of the calice. Dissepiments very oblique and crowded. Wal/s delicately striated, 
devoid of epitheca, but presenting at certain points circular foliaceous expansions.
