Catalog entries: Dictyocephalus amphora

Original description: Shell smooth, thick-walled, subovate, with slight collar stricture. Length of the two joints = 5: 9, breadth = 6: 8. Cephalis large, obtusely conical, with numerous oblique pore-canals. Thorax inflate, with six to eight transverse rows of roundish pores, increasing in size towards the base. Mouth constricted, one-third as broad as the thorax, with an internal diaphragm and a narrow hyaline peristome.

Cephalis 50µm long, 60µm broad; thorax 90µm long, 80µm broad.
Remarks on original description: Haeckel listed Dictyocephalus amphora under the subgeneric name Dictyoprora, but did not include the subgeneric name in the species name.
