Description:
Shell small for genus (
holotype
31.1 mm
sl), narrowly fusiform, with rounded whorls, broad axial ribs, well-developed spiral cords, shallow suture, and narrow post-sutural ramp bearing closely-packed axial lamellae. Teleoconch of about 7 regularly expanding convex whorls separated by shallow suture; suture undulant in accord with adjacent whorls and interspaces; each whorl with about 8 broad axial ribs; 4 subequal spiral cords on first whorl, enlarging in size but not increasing in number on succeeding whorls of spire, 10–11 cords on body whorl; cords on sutural ramp low, parallel to and undulating in concert with suture, crossed by numerous welldeveloped subsutural lamellae; cords crossing ribs larger than those of ramp, sometimes with single spiral threads between; 6 or more oblique cords of unequal size on siphonal process, occasionally with single smaller thread between. Aperture ovate, constricted adapically by thick parietal node and abapically by small tooth-like node opposite fold at base of columella; outer lip broadly arcuate, rendered serrate by extensions of interspaces between spiral cords, inner surface with about 8 beaded lirae; columella with 4 oblique plicae, another smaller plica adapically; siphonal canal typical of genus, outer lip thin, crenulated by termini of interspaces between larger dorsal cords, inner lip simple, straight. Shell outer surface yellow with white axial ribs on first 3 or 4 teleoconch whorls, interior white. Operculum and radula unknown.

Remarks
: The
holotype
of
Turbinella attenuata
Reeve, 1847
resembles shells in the
Pustulatirus virginensis
species-complex of the eastern Caribbean and also resembles shells of a new species from
Honduras
and
Panamá
that is described herein, yet it differs from both.
Described without locality,
T. attenuata
was soon recognized as a western Atlantic species by nineteenth century authors (Mørch 1852, Krebs 1864, Kobelt in Küster & Kobelt 1876, Kobelt 1876, 1877, Arango y Molina 1880). However, Kobelt in Küster and Kobelt (1876) suggested that the name might represent a variety of
Turbinella infundibulum
(Gmelin, 1791)
, now the
type
species of
Polygona
Schumacher, 1817
, prompting Tryon (1881) to relegate the name to synonymy with that species. Tryon’s action effectively shelved the name until Abbott (1958) mentioned specimens at ANSP, previously labeled
Latirus attenuatus
, among those he was naming
L. virginensis
. Bullock (1968, in thesis) also addressed the name but distinguished it as a species separate from
L. virginensis
and others in a related species-complex (see below). The name (as
Turbinella attenuale
[
sic
]) also appeared on an early list of shells from
St. Martin
prepared by H. E. Rijgersma, but Coomans (1974) dismissed it as a supposed synonym of
Latirus
[=
Polygona
]
brevicaudatus
(Reeve, 1847). Then Sutty (1986: 62, 64, 65, fig. 70) reported and figured as “
Latirus
species (
cf.
attenuatus
(Reeve, 1847))
” a shell from
Guadeloupe
that in her opinion “bears a distinct resemblance to
Latirus virginensis
Abbott, 1958
and, better still, [to]
L. attenuatus
(Reeve, 1847)
.” Thereafter, Snyder (2003) cited
L. attenuatus
as a valid Caribbean species that ranged from
Cuba
to the Lesser Antilles, apparently sympatrically with
L. virginensis
. Mallard and Robin (2005) cited
L. attenuata
[
sic
], range
Cuba
to Lesser Antilles, and
L. virginensis
, range “Caribbean,” again suggesting sympatry. Those authors speculated that
attenuata
may be the species they figured as
L. bernadensis
Bullock, 1974
, on their plate 41, but that shell was correctly identified and is a species of
Polygona
. Vermeij and Snyder (2006) reclassified both
attenuatus
and
virginensis
in
Pustulatirus
and treated them as distinct. In this we concur. However, we include other shells figured as
attenuatus
by Bullock (1968), Sutty (1986) and Vermeij and Snyder (2006) in
Pustulatirus virginensis
.
