Only in the N.Z. area. At Station 6 it is abundant and attains a large 

 size. The test is constructed very roughly of large sand-grains, smaller grains 

 embedded in cement being used to fill the interstices. The aperture is a narrow 

 slit situated at the end of a produced neck, constructed of finer material. At 

 Station 10 a single specimen utilizing the tests of other Foraminifera as building 

 material was found.

Few records, but the species occurs in both areas. The N.Z. specimens are 

 very coarsely built. Most abundant and exhibiting considerable variation at 

 Station 40. Terquem's species is so well recognised in association with Brady's 

 figure that we cannot agree with Cushman^'s erection of the well known type 

 into a separate species under the name of Ammobaculites americanus, on the ground 

 that Terquem's species is concavo-convex in section. Although Terquem refers 

 to this in his text, his figures are clearly the same as Brady's, and give but the 

 faintest indication of the convexity, probably not more than is indicated in 

 Brady's figure of the species.

This can only be regarded as a thin-walled variety of H. canariense, but 

 it exhibits a striking tendency to build largely of sponge-spicules and micaceous
