Original Description
DESCRIPTION : Enroulement trochospiralé comprenant environ 2 tours 1/2. Test faiblement biconvexe, nettement comprimé latéralement. Loges de forme ovale ou spatulée, au nombre de 5 au dernier tour, s'accroissant assez rapidement. Ouverture primaire intériomarginale ombilicale-extraombilicale-périphérique, bordée par une lévre assez marquée. Ombilic trés étroit. Sutures radiales et déprimées. L'angle de raccordement entre les faces dorsale et ventrale est assez aigu, mais il n'y a pas de caréne et le bord périphérique est arrondi, tout au plus souligné par une concentration de pustules.
Translation (from Chronos):
Diagnosis: The species is characterized by its strongly compressed test and its lobate outline. The chambers, numbering 5 in the last whorl, are radially elongate and increase rapidly in size. The umbilicus is very narrow and the profile almost symmetrical.
Description. Trochospiral mode of coiling, comprising about 2 whorls and a half. Weakly biconvex, clearly compressed.

Primary aperture interiomarginal , umbilical-extraumbilical -peripheral in position, bordered by a fairly noticeable lip. Umbilicus very narrow. Sutures radial and depressed. The dorsal and ventral sides converge in an acute angle, but there is no keel and the peripheral edge is rounded, at best marked by a concentration of pustules.

Repartition stratigraphique : A Puget-Théniers, les premiers représentants de l'espèce font leur apparition à un niveau assez élevé du Coniacien inférieur et H. flandrini semble se poursuivre au-dela de la limite supérieure de la série.
