Eulimella sp. 1

Fig. 12A View Fig .

Material.— One shell ( SMF373103 About SMF ) from Northern Indian Ocean, Krishna-Godavari Basin , Bay of Bengal, offshore eastern India, 15°51.6335’ N, 81°50.2274’ E, 1046 m water depth, 16.68 mbsf level, core NGHP-01-12A; Upper Pleistocene GoogleMaps .

Description.—Highly elevated shell, eullimelliform, smooth with fine apex. Protoconch sinistral, axis rotated about 120° from spire axis, one whorl, smooth, diameter about 300 µm. Teleoconch dextral, smooth, with fine orthocline growth lines, seven whorls, slightly convex above deeply impressed suture, ultimate whorl below suture with straightened columella. Aperture trapezoidal.

Remarks.—Placement in Eulimella is based on the smooth elevated shell and the rotated heterotrophic protoconch. However, the single shell is considered as inadequate for a description.

Eulimella sp. 2 Fig. 12B View Fig .

Material.— One shell ( SMF373104 About SMF ) from Northern Indian Ocean, Krishna-Godavari Basin , Bay of Bengal, offshore eastern India, 15°51.6335’ N, 81°50.2274’ E, 1046 m water depth, 16.38 mbsf level, core NGHP-01-12A; Upper Pleistocene GoogleMaps .

Description.—Highly elevated shell, eullimelliform, smooth, with large apex. Protoconch sinistral, axis rotated about 100° from spire axis, one whorl, smooth, diameter about 300 µm. Teleoconch smooth with fine orthocline growth lines, four and half whorls, maximum convexity at periphery, deeply impressed suture, ultimate whorl below suture with straightened columella. Aperture trapezoidal.

Remarks.—Placement in Eulimella is based on the smooth elevated shell and the rotated heterotrophic protoconch. However, the single shell is considered as inadequate for a description.

Fig. 12C View Fig .

Material.— One shell ( SMF373105 About SMF ) from Northern Indian Ocean, Krishna-Godavari Basin , Bay of Bengal, offshore eastern India, 15°51.6335’ N, 81°50.2274’ E, 1046 m water depth, 16.38 mbsf level, core NGHP-01-12A; Upper Pleistocene GoogleMaps .

Description.—Highly elevated shell, eullimellid shape, smooth with large apex. Protoconch sinistral, axis rotated about 100 degrees from spire axis, one whorl, smooth, diameter about 300 µm. Teleoconch smooth with fine orthocline growth lines, four and half whorls, maximum convexity at periphery, deeply impressed suture, ultimate whorl below suture straightened columella. Aperture trapezoidal.

Remarks.—Placement in Odostomia is based on the protoconch and on the smooth conical shell with flattened whorls.

The single shell is too poorly preserved for a more detailed description.
