Ak. Forh. 1878, no. 3, 15. 



Zoarium subcircular, very convex^ at times subcorneal, with 

 a small central area destitute of cells, the laminar border 

 narrow. Zocecia rather stout, moderately raised, dis- 

 posed more or less regularly in radiating lines, not con- 

 nate, frequently traversed by longitudinal ribs ; orifice 

 obliquely elliptical, the margin carried up into a tall 

 acuminate process ; cells round the border of the disk 

 not elevated, quincunciab orifice subcircular. Ooecium 

 an inflation of the surface of the disk ; orifice trumpet- 

 shaped. 



This is a small species, with the zoarium always simple, 

 and the cells, which are proportionally large, discon- 

 nected and arranged in short, radiating rows. The orifice 

 is for the most part elliptical, and the upper margin is 

 elevated and acuminate ; occasionally the peristome is 

 bifid. The zooecia are generally buttressed in front by 

 longitudinal ribs, Avhich are sometimes serrate. 



* It is a matter of extreme dilBciilty to determine the synonymy with any 

 certainty in this section of the Cyclostomata. Heller identifies his species 

 with the M. vemtcaria of Fabr. ; but his diagnosis is quite insufficient. 



As Busk has already pointed out, Smitt has wrongly referi-ed D. flosculn.% 

 iiiihi. to the present species.
