Distribution of E. veteratoris n.
sp. (1): Recorded only from the type
locality and horizon.
Etymology of E. veteratoris n.
sp. (1): Latin adjective, veteratoris,
of the wise old fox. Named in honour of Jacques LE RENARD, distinguished
palaeontologist and pioneer of research on the type horizon.
Additional material examined of E.
veteratoris n. sp. (1): 10,
mostly fragmentary examples in private collections.
Diagnosis of E. veteratoris n.
sp. (1): Moderately small, rather smooth
conical shell with sharp shoulder with small rounded nodules, a low, somewhat coeloconoid,
more or less nodular spire and a paucispiral protoconch.
Description of E. veteratoris n.
sp. (1): Protoconch diameter c. 730 μm., paucispiral, of 2 smooth, convex whorls with a sinuous lip ; initial
whorl globular, diameter 300 μm.. Spire profile somewhat
coeloconoid, flattening and becoming more regularly turreted later ; spire
whorls ornamented above with raised growth lines tracing a deep semicircular
sinus and 4-5 subordinate fine spiral cords ; lower part of whorls with c. 12
short, rounded tubercles resting on the lower suture, which may become fused
with growth to form an angular shoulder. Last whorl slightly sinuous in
profile, smooth but with fine spiral cords towards the base. Aperture parallel
sided, columella/paries junction shallowly indented Outer lip slightly flared,
gently curved. Holotype 30.5 x 13 mm.
Discussion of E. veteratoris n.
sp. (1): Similar in general appearance to E.
diversiformis (Deshayes, 1835) but distinguished from that and other known Eoconus
and Conilithes species by the shorter protoconch, and from
Conilithes by the spiral ornament on the whorl tops.
