with fine longitudinal rows of fine granules 4. yj. tenuis.

Stat. 267. 5°54'S., I32°56'.7E. 984 m. A dead fragment. 

 Stat. 297. io°39'S., i23°4o' E. 520 m. A small branch. 



In the Indian Musevmi there is a large piece of this species from the X. Atlantic 

 {^ Caudan" Expedition) some of the smaller branches of which agree in every respect with the 

 Siboga fragment from Station 297. As to the identity of the small dead fragment from Station 

 267, I am not quite certain. 



Distribution. N. Atlantic, Mediterranean, deep basins of East Indian Archipelago. 



51. AmphiJielia raiiica Mliller, Duncan. 



Anipliilulia rainea Martin Duncan. Trans. Zool. Soc. Lond. VIII, 1S74, p. 326, pi. XLIV. 

 figs. I — 3, pi. XLV. figs. 4 — 6, pi. XLVI. figs. I — 19. 



Stat. 95. 5°43.5N., ii9°4o' E. 522 m. Two dead fragments. 

 Stat. 156. o°29'.2 S., 130° 5'.3 E. 469 m. Some dead fragments. 

 Stat. 251. 5°28'.4 S., 132° o'.2 E. 204 m. Some fine branches. 



According to Martim Duxcax all Diplohclitr with costal strict are referable to this 

 species, which thus includes Ainphihclia iiiioccrnica Seguenza, AiiipJiiliclia atlantica and ornata 

 Duncan, Diplohelia mencgliiniana and d'dderlcinia and sisiiiondiana Seguenza, and Diplohclia 

 profunda Pourtales. The last named, however, is a Coenopsaniniia. 



The fine specimens which I identify with this variable species exhibit very close and 

 regular budding and but slight tendency to anastomosis. 



Distribution. Both sides of N. Atlantic, East Indian Archipelago; Sicilian Tertiaries.

Stat. 12. 7° 15' S., II5°I5'.6E. 289 m. Two small fragments. 

 Stat. 95. 5°43'.5X., ii9°4o' E. 522 m. Numerous branches. 

 Stat. 156. o°29'.2 S., 130° s'.3 E. 469 m. A small fragment. 



This species differs from A. oculata chiefly in the greater density of the coenenchyma 

 and the poli.sh of its surface, and in the greater depth of the calicles. In some of the calicles 

 there are small paliform lobes on the septa of the second cycle. 



Distribution. East Indian Archipelago.
