2. Anthosiiyris spathulata, n. sp. (PL 87, fig- 15). 



Shell subspherical, thoruy, with slight sagittal stricture and irregular, roundish pores. Basal 

 plate with three large pores. The three horns spindle-shaped, half as long as the ten to twelve 

 thin feet, which are pediculate, shovel-shaped, a little divergent, and shorter than the shell. 



Dimensions. — Shell 0-05 diameter ; horn 002 long, feet 004 long. 



Habitat. — Xorth Pacific, Station 250, depth 3050 fathoms. 



3. Anthospyris diaboliscus, Haeckel. 



Petalospyris diaboliscus, Elireiiberg, 1854, MLkrogeol., Taf. xxxvi. fig. 12 ; Abhandl. d. k. Akad. 

 d. Wiss. Berlin, 1875, p. 80, Taf. ssii. fig. 3. 



Shell nut-shaped, smooth, with slight sagittal stricture and small circular pores. Basal plate 

 with four large pores. . Apical horn straight conical, frontal horns curved laterally. Feet nine to 

 twelve, of about the same length as the horns and the shell, broad lamelliform, truncate, nearly 

 vertical, slightly curved. 



Diimnsions. — Shell 0-04 long, 0-07 broad ; horns and feet 0-05 to 0-07 long. 



Habitat. — Fossil in Barbados. 



4. Anthospyris arachnoides, Haeckel. 



Petalospyris arachnoides, Haeckel, 1862, Monogr. d. Radiol., p. 294, Taf. xii. fig. 7. 



Shell nut-shaped, tuberculate, with slight sagittal stricture and irregular, polygonal pores. Basal 

 plate with four large pores (?). Apical horn straight, conical, longer than the two curved lateral 

 horns. Feet ten, slender, S-shaped, widely divergent, about as long as the sheU is broad. 



Dimensions. — SheU 0-05 long, 0-08 broad ; horns O'OS to 0-05 long, feet 0-08 long. 



Habitat. — Mediterranean (Messina), Atlantic, Station 354, surface. 



5. Anthospyris aculeata, n. sp. (PI. 86, fig. 5). 



Shell campanidate, spiny, with deep sagittal stricture and irregular, roundish pores. On each 

 side of the stricture three pairs of larger annular pores. Basal plate with two large square pores. 

 The three horns of the same size as, and similar form to, the ten to fifteen feet, slender pyramidal, 

 straight, divergent, about half as long as the shell. (This species is very variable and closely allied 

 to Ceratospyris.) 



Dimensions. — Shell diameter 0-08 to 0-12 ; horns and feet 0-04 to 0-06 long. 



Habitat. — Central Pacific, Stations 266 to 274, surface. 



6. Anthospyris doronicum, n. sp. (PI. 87, fig- 18). 



SheU nut-shaped, spiny, with a deep sagittal stricture and smaU circular pores. On each side 



of the stricture two pairs of very large square annular pores. Basal plate with four larger coUar
