TEOPICAL PACIFIC FORAMINIFERA OF ALBATROSS 43 



There are numerous records for this species showing its wide dis- 

 tribution in the Indo-Pacific region from Kerimba Archipelago off 

 southeast Africa to the Philippines and southward to Australia. 

 Very similar specimens occur in the lower Oligocene, Byram marl. 

 This is easily confused with the flattened forms of Planispirina, 

 which often occur in the same locality. It may be noted here that 

 the specimens referred to this species in United States National Mu- 

 seum Bulletin 71 (pt. 6, pi. 24, fig. 4, 1917) are not Hauerina, but 

 should be placed in Planispirina.

Test compressed, early chambers milioline, later ones either em- 

 bracing and extending in the center to cover the previously 

 formed chambers or becoming elongate and more or less encircling 

 the periphery; surface ornamented by strong transverse or radial 

 ridges or crenulations crossed by numerous fine longitudinal striae; 

 aperture consisting of numerous small pores in several linear series or 

 scattered, the sieve plate thus formed extending the full height of the 

 chamber. Diameter, up to 1.5 mm. 



Although this species is typically an Indo-Pacific one, it occurs 

 sparingly in the West Indian region, but specimens are never so well 

 developed as in the Pacific and Indian Oceans. Forms referable to 

 this species also occur in the Oligocene of the Gulf Coastal Plain of 

 the United States. The types described by Karrer are from the 

 Miocene of Europe. 



In our collections the species is often abundant and occurs at the 

 following localities: Levuka, Fiji, 12 fathoms; Mokaujar Anchorage, 

 Fiji; Nairai Islands, Fiji, 12 fathoms; Rotonga, 7 fathoms; Makemo
