sharply costate. Such forms are widely distributed and seem never 

 to have any considerable number of linear chambers. Reuss's types 

 were from the Miocene of central Europe and should be compared 

 with the various forms referred to this species from widely separated 

 regions. These specimens figured are from Mokaujar Anchorage, 

 Fiji, and the species occurred also at Albatross Station H3984, off 

 entrance to South Pass, Rongelap, Marshall Islands, in 746 fathoms. 

 This is marked as coarse coral sand and undoubtedly represents 

 material carried out from shallow water.

Genoholotype. — Nubecularia divaricata H. B. Brady. 



Test elongate, uniserial; initial end coiled or milioline; chambers 

 distinct, simple; wall imperforate, porcelaneous, with sand grains 

 attached to the exterior ; aperture at the end of an elongated tubular 

 neck with an everted phialine lip, the apertural opening with a series 

 of inwardly pointing teeth. 



This genus is known only from the Indo-Pacific and is there repre- 

 sented by several forms. Three of these were found in the material 

 recorded here. They occur in comparatively shallow water, and some 

 of the forms reach a large size.
