Description. — Test composed of a series of Globigerina-Mke cham- 

 bers followed by and inclosed by a globular chamber, surface reticu- 

 late with a pit at the bottom of each reticulation and one larger, 

 circular aperture; surface with long spines in the living condition. 



Diameter up to 1 mm. 



Distribution. — Little need be said of the distribution of this species 

 which seems to be found nearly always in any sample of typical 

 Globigerina ooze. Brady simply speaks of it as cosmopolitan. Bagg 

 records it from all 19 of the Albatross stations from which he exam- 

 ined material from off the Hawaiian Islands. Picaglia notes it 

 from two stations of the Vettor Pisani in the North Pacific. Flint 

 notes it from various Nero stations. 1 



I have found it common in material from the Albatross, Nero, Tus- 

 carora, and Alert soundings wherever such soundings came into the 

 regions of Globigerina ooze. 



There is a tendency in specimens to show many layers in the wall 

 of the final chamber, and it may be that the test increases by addition 

 of material from without and resorption from within. At least
