Habitat.—South Pacific, Station 300, depth 1375 fathoms.
Genus 637. Phormocampe,[[254]] n. gen.
Definition.—Stichophormida (vel Stichocyrtida multiradiata aperta), with conical or pyramidal shell, without lateral ribs. Mouth dilated, with a corona of terminal feet.
The genus Phormocampe may be derived from the preceding Stichophormis by loss of the lateral ribs, whilst the terminal feet remain. It bears therefore to the latter the same relation that Calocyclas exhibits to Theophormis among the Tricyrtida.
Subgenus 1. Anthocorys, Haeckel, 1881, Prodromus, p. 437.
Definition.—Shell with three transverse strictures or annular septa, and with four distinct joints.

Anthocorys campanula, Haeckel, 1881, Prodromus et Atlas (loc. cit.).

Cephalis three-sided, pyramidal, slender, bearing a pyramidal horn of the same length, with three dentate edges. Thorax very small, hemispherical. Third joint very large, campanulate. Fourth joint of the same breadth, but only one-third as long. Pores subregular, circular. Peristome with a coronal of twelve to fifteen conical, divergent feet, as long as the last joint.
Dimensions.—Length of the shell (with four joints) 0.18, breadth 0.09. Length of the single joints, a 0.05, b 0.02, c 0.08, d 0.03.
