Affinities. 
Pergens describes d’Orbignj’s figures as bad, and a part of 
a typical specimen is accordingly here figured (Xo. 34). The 
specimen differs from d’Orbigny’s representation by having a larger 
area below the aperture, and the zooecia accordingly appear 
hexagonal instead of rhomboidal ; but in parts of the zoarium 
where the transverse rows of apertiu'es are nearer together, tlie 
front wall is smaller. M. ogivalis, Orb., appears to be this species 
with the peristomes worn down and thus enlarged.

Diagnosis. 
Zoarium of branches 2 - 2*5 mm. in diameter ; they divide 
dichotomously, and form a tufted zoarium. 
Zooecia with very long, narrow, axial prolongations. ,The distal 
ends are large. 
Apertures about twelve in a circuit of a branch. They are 
arranged in regular, crowded whorls ; those of adjacent series 
are alternate, so that the zooecia are quincuncial. Apertures 
triangular or semicircular in shape, with a slightly raised 
peristome. The aperture is nearly as large as the small 
triangular front wall.
