3. Haeckeliana lamarckiana, n. sp. (Pl. [114], fig. 4).
Shell with thirty-five to forty coronets, the majority of which have five pores (more rarely six or four). Coronets broader than their intervals; each funnel-shaped pore on the inside with a circle of small conical thorns. By-spines rudimentary or wanting. Dimples irregularly polygonal, half as broad as the pores. Radial main-spines shorter than the radius.
Dimensions.—Diameter of the shell 0.38 to 0.45, of the coronets 0.06 to 0.07.
Habitat.—South Atlantic, Stations 318 to 333, depth 2000 to 2900 fathoms.
4. Haeckeliana murrayana, Haeckel.
Challengeria sp., John Murray, 1876, Proc. Roy. Soc., vol. xxiv, pl. xxiv. fig. 6.
Shell with twenty to twenty-five coronets, the majority of which have five pores (more rarely four or six). Coronets of about the same breadth as their intervals, and twice as broad as the by-spines. Dimples subcircular, of about the same breadth as the pores. Radial main-spines about as long as the radius.
Dimensions.—Diameter of the shell 0.35 to 0.4, of the coronets 0.06 to 0.07.
Habitat.—Central Pacific, Stations 271 to 274, depth 2350 to 2750 fathoms.
