Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. R. Loeblich and H. Tappan 1987 | Test elongate, early stage triserial and sharply triangular, later biserial, chambers with fistulose projections at the lateral angles, and later chambers with similar projections in vertical rows on the chamber face, the rows occasionally bifurcating so that the adult test may have six to eight such rows of tubular outgrowths that form small chamberlets external to the main chamber wall and cavity, lacking any connection with the test interior other than through the wall canaliculi, fistulose chamberlets also closed to the exterior in well-preserved specimens but commonly broken, irregular to vermiform openings of the wall canaliculi may be seen through the opening left into the chambers when tops of some or all projections are work or broken; wall agglutinated, that of the sides of the test itself distinctly canaliculate but wall of the tubular projections, septa and apertural face non-canaliculate, opening of the canaliculi irregular, the path of the pores then straight through the wall itself; aperture a low arch at the base of the apertural face, small and nearly circular in young specimens, forming a somewhat more elongate slit in the adult. Holocene; Indo Pacific.
Siphoniferoides was originally placed in the subfamilly Gaudryininae, family Verneuilinidae, but has a canaliculate wall whereas the Gaudryinidae are noncanaliculate. |
