Dimensions.—Shell 0.09 long, 0.11 broad; horn and feet 0.4 to 0.6 long.
Habitat.—Central Pacific, Stations 270 to 274, depth 2350 to 2925 fathoms.
3. Dorcadospyris lunulata, n. sp.
Shell subspherical spinulate, nearly of the same shape as in the preceding species, but with a short conical horn (scarcely as long as the shell); the feet are much mere slender, crescentic, and bear twenty to thirty smaller smooth conical teeth (shorter than the shell). The distal ends of the feet are crossed.
Dimensions.—Shell 0.08 long, 0.09 broad; horn 0.06 long, feet 0.03 to 0.06 long.
Habitat.—Central Pacific, Station 266, depth 2750 fathoms.
4. Dorcadospyris decussata, n. sp. (Pl. [85], fig. 7).
Shell subspherical, smooth, very similar to that of the two preceding species. Horn small conical, about as long as the shell. Feet more than semicircular, more strongly curved than in any other species, each with four to eight small conical teeth, shorter than the shell; distal ends crossed. (In this species also, besides the normal symmetrical form, there often occurs an asymmetrical form of the two feet; one of these frequent anomalies is shown in fig. 7.)
Dimensions.—Shell 0.06 long, 0.08 broad; horn 0.05, feet 0.2 to 0.5 long.
Habitat.—Central Pacific, Stations 265 to 268, depth 2700 to 2900 fathoms.
