Genoholotype. — Carpenteria hakniijormis Gray. 



Test attached, early chambers trochoid, later spreading out over 

 the surface of attachment both with the inner ends piled up in a loose 

 spire or the whole test becoming subcylindrical, the chambers loosely 

 spiral or even uniserial; wall calcareous, coarsely perforate; aperture 

 in the young narrow, in the older stages somewhat rounded at the 

 end of a tubular projection, and in the uniserial forms sometimes 

 with a tubular neck. 



This genus is apparently present in the Cretaceous and certainly 

 in the Eocene. Some of the species have a widely spreading form with 

 little building up into a high spire, while others develop a very long 

 test. The representatives of the genus are most abundant in the 

 shallow water of the Indo-Pacific although at leS.st one species or 

 variety has become adapted to fairly deep water.

Test attached, columnar, basal portion usually somewhat spreading 

 and buttressed; early chambers coiled, attached by the dorsal side but 

 covered by the later ones which become much inflated and built up 

 into an irregular, subcylindrical column of a few chambers; wall 

 coarsely porous; aperture often with a tubular neck and slight lip. 



Length up to 6 mm. 



This species is often abundant in fairly deep water in the West 

 Indian region where it attains a large size. The types are from the 

 Caribbean. The Challenger records are as follows: "Off Culebra
