Catalog entries: Clathrocircus stapedius

Original description: Sagittal ring ovate, smooth, with six pairs of pores (two apical and four basal). The four apical pores are of nearly equal size and form a quadrangular mitral plate with two large lateral horns. The eight basal pores are of very different size (the four central far larger than the two anterior and the two posterior), and form a hexagonal basal plate, also with two large lateral horns. The four branched lateral horns (two upper and two lower) form together an incomplete frontal ring.
Remarks on original description: Although Haeckel does not define \q" in the figure explanations, it is clear from the family discussion of Coronida (p.967-969) and from the above description, that he means "q" to designate the incompelre lateral or frontal ring. Haeckel seems to use the inverted "a" for a variety of designations, and nowhere gives any specific explanation for its use."[comment from RadWorld database]
