FORAMINIPERA OF THE ATLANTIC OCEAN 63 



Length, 0.70 mm.; breath, 0.35 mm.; thickness, 0.20 mm. 



Most of the records for this species are from the Indo-Pacific where 

 it is known from the Kerimba Archipelago off the east coast of 

 Africa to Torres Strait and the Malay Archipelago. 



In the West Indies I have had it from Montego Bay on the north 

 coast of Jamaica, from Porto Rico, and from the Tortiigas region. 

 Heron-Allen and Earland record it from Havana, Cuba. The speci- 

 mens from Porto Rico while they have the shape of the others do not 

 always show the sm'face ornamentation as well.

The original figure given by Soldani is here copied. Except for 

 this figure copied from the original by Parker, Jones, and H. B. Brady, 

 the species has been recorded several times without being figured. 

 The specimen shows a test that is longitudinally co'state, the periph- 

 ery slightly sinuous and the apertural end produced with a much- 

 contracted neck and small rounded aperture. 



I have not seen the species in the western Atlantic, though it is 

 recorded from about the British Isles and the Pacific region. 



Heron-Allen and Earland (1913, p. 33) make the following state- 

 ment : 



In M \ilionina] Brongniarlii the shell is typically oval or nearly circular in 

 outline; the aperture is broad and practically flush with the periphery; and the 

 sutural depressions between the chambers are very slightly marked. The out- 

 line of the test as seen in section would be lenticular. The striae are fine, and 

 follow the outline of the chambers in curved parallels. 



This would give a form somewhat different from that figured by 

 Soldani.
