 lactea.

Polymorphina lactea Walker and Jacob, var. amygdaloides H. B. Brady, Parker, 

 and Jones, Trans. Linn Soc. London, vol. 27, 1870, p. 214, wood cuts. 



Description. — Test oval, somewhat compressed, cross-section elip- 

 tical, chambers few, elongate, sutures only very slightly depressed; 

 wall smooth. 



Length 0.6 to 1 mm. 



Distribution. — Bagg records the species from three Albatross stations 

 in the vicinity of the Hawaiian Islands, D4017, 305 fathoms; D4174, 

 735-865 fathoms; and H4567, in 1,307 fathoms. 



I have found no material to place in this species. The figures are 

 drawn from the specimens recorded by Bagg.

 Globulina gibba d'Orbigny, For. Foss. Vienne, 1846, p. 227, pi. 13, figs. 13, 14. 



Description. — Test rotund, front view nearly circular, end view 

 broadly oval; visible chambers few; broad sutures slightly excavated; 

 wall smooth, aperture somewhat produced. 



Length 0.75 to 1 mm. 



Distribution. — Bagg records this species from one station only, 

 Albatross H4430, rarely, in 1,544 fathoms, off the Hawaiian Islands. 

 The specimen I have examined, and it is typical. I have a single 

 specimen from Albatross D4807, in 44 fathoms, off Japan.
