.
Diagnosis.
Test is free, stout, elongated, and slightly tapering toward the rounded initial end. Chambers are not distinctly marked externally. Early triserial stage is not clearly observed in exterior, and the later portion is uniserial with slightly depressed sutures. Wall is composed of fine to coarse heterometric sediment grains and the test surface is greyish in color. Aperture is terminal, rounded, and somewhat flaring at the end of a short neck. Test length is about
2.95 mm
.
Remarks.
This species is originally classified as
Clavulina bradyi
by
Cushman (1911)
, and later accepted to
Cylindroclavulina bradyi
as a
type
species of the genus
Cylindroclavulina
by
Bermúdez and Keys (1952)
. There are four modern species belonging to this genus (
Hayward
et al.
, 2018b
):
C. atlantica
,
C. bradyi
,
C. elongata
and
C. ovata
.
Cylindroclavulina bradyi
is morphologically most similar to
C. elongata
, but the latter has more narrowly elongate test, more distinct neck and teeth, and more loosely agglutinated test wall (
Ellis and Messina, 1940
). The present specimen is somewhat more elongated and slenderer than the
type
specimens described by
Cushman (1911)
and very similar to the specimens recorded by
Jones (1994
, plate 48, figure 32) and
Debenay (2012)
.
