REPORT ON THE RADIOLARIA. 1347 



Subgenus 4. Podocyrtonium, Haeckel. 



Definition. — Feet convergent (the distance between their ends being smaller than 

 that between their bases). Pores of the thorax and abdomen different in size or form. 



34. Podocyrtis 2^edicellaria, n. sp. (PI. 72, fig. 8). 



Shell conical, ovate, with two very slight strictures. Length of the three joints = 2:3:8, 

 breadth = 2:4:8. Cephahs conical, with a pyi-amidal horn of the same length. Pores subregular, 

 circular, quincuncially disposed, two to three tunes as broad in the smooth abdomen as in the 

 rough, spinulate thorax. Feet as long as the thorax, shovel-shaped (broad, triangular, with convex 

 outer and concave inner side, the free ends being curved inwards), only shghtly convergent. 



Dimensions. — Length of the three joints, a 0-04, h 0-05, c 016 ; breadth, a O'OS, h O'OQ, c OIG. 



Hahitat. — Central Pacific, Stations 265 to 268, depth 2700 to 2900 fathoms. 



35. Podocyrtis sinuosa, Ehrenberg. 



Podoctjrtis sinuosa, Ehrenberg, 1875, Abhandl. d. k. Akad. d. Wiss. Berhn, p. 82, Taf. xv. fig. 5. 

 Podocyrtis sinuosa, Biitschli, 1882, Zeitschr. f. wiss. Zool., vol. x.xxvi. p. 540, Taf. xxxiii. fig. 33. 



Shell slender, conical, with shght collar, but without lumbar stricture. Length of the three 

 joints = 1:2:4, breadth = 1 : 2 : 4. Cephalis subspherical (in the figure of Ehrenberg broken off), 

 with a pyramidal horn of the same length. Pores subregular, circular, four times as broad in the 

 abdomen as in the thorax. Peet shovel-shaped, as long as the thorax. 



Dimensions.— 'Le.wgih. of the three joints, a O'O.j, h 0-06, c 012; breadth, a O'OS, h 0-06, c 012. 



Hahitat. — Fossil in Barbados. 



36. Podocyrtis florihunda, n. sp. 



Shell ovate, conical, with two very shght strictures. Length of the three joints = 2:3:6, 

 breadth =2:4:7. Between twenty-four to thirty longitudinal, denticulated ribs lie the same 

 number of subregular pores, which are flower-like, lobed, or rosette-shaped, and two to three times 

 as large in the abdomen as in the thorax. Feet shovel-shaped (as in the similar Podocyrtis 

 pedicellaria (PI. 72, fig. 8). 



Dimensions. — Length of the three joints, a 0-03, h O'OS, c 012 ; breadth, a O'Cl, h 0-08, c 014. 



Habitat. — Tropical Atlantic, Station 342, depth 1445 fathoms ; also fossil in Barbados. 



37. Podocyrtis scaphopodia, n. sp. 



Shell conical, rough, with two slight strictures. Length of the three joints = 2:3:5, breadth 

 = 2:4:8. Cephalis subspherical, with a pyramidal horn of twice the length. Poi'es subregular.
