Boudagher-Fadel et al. (1997): Remarks: This subspecies differs from the typical form of the species in having peripheral intercameral sutural angles of about 150° and more depressed chambers in the last whorl (h/L = 0.8 approx.), producing a more compact test. The chambers of the last whorl become less depressed during growth, and the final chamber is only slightly lower than long. A specimen of H. (H.} sigali figured by Moullade (1966, plate 7, fig. 20), in spite of a rather poor optical photograph taken at a slightly oblique angle (our Plate 7.3, Fig. 9), resembles the subspecies enough to be included here. |
