Subgenus 2. Lamprocycloma, Haeckel.
Definition.—Feet of the peristome forked or branched.
7. Lamprocyclas bajaderæ, n. sp.
Shell campanulate, very similar to the preceding species, but with stronger spines on the abdomen and with different peristome. Length of the three joints = 2 : 2 : 3, breadth = 2 : 6 : 8. Cephalis equal to that of Lamprocyclas maritalis (Pl. [74], figs. 13, 14). Outer coronal of the peristome with fifteen to twenty divergent, pyramidal feet, half as long as the horn; inner coronal with as many longer, vertical feet, which are irregularly forked or branched.
Dimensions.—Length of the three joints, a 0.04, b 0.04, c 0.06; breadth, a 0.04, b 0.12, c 0.16.
Habitat.—South Pacific, Station 298, depth 2225 fathoms.
Genus 608. Diplocyclas,[[225]] Haeckel, 1881, Prodromus, p. 434.
Definition.—Theophormida (vel Tricyrtida multiradiata aperta) with a double corona of radial solid feet, an upper around the lumbar stricture, a lower around the mouth. No ribs in the shell-wall.
The genus Diplocyclas differs from all the other Theophormida in the possession of a double coronal of radial teeth, an upper between thorax and abdomen, and a lower around the terminal mouth of the latter; it may be regarded as an Anthocyrtis, which has formed an abdomen, and repeated the terminal armature. The cephalis bears a single or double apical horn.
1. Diplocyclas bicorona, n. sp. (Pl. [59], fig. 8).
