The characters are enough to separate the specimen from gave the impression to the above attribution. the similarly shaped naticoidean forms in the Kachchh Distribution in Kachchh — Upper Callovian Wasfauna (SZABÓ & JAITLY 2004). The peristome characters thawa Formation, Wasthawa section, Wagad. Family Aplustridae GRAY, 1847 Genus Valaeohydatina COSSMANN, 1895 Palaeohydatina ? sp. (Plate I: 19-20) Material — A single, somewhat deformed steinkern with remnants of outer ornament of the last whorl. Measurements H HL BHU20011 58 36.0 36.0 Description — Ovate, strongly involute shell, spire whorls not visible, however, narrow spire umbilicus seems to exist; acute apex inferable at coiling axis. Height of peristome equal with height of complete shell. Aperture narrow, arched from apex to short columella; aperture downward slightly widening. No part of peristome preserved except short columellar neck with traces of rather broad siphonal outlet. Spiral fold inferable on HP D WP AA AL 36.0 20.5 15.0 columella. Growth lines prosocyrt. Remarks — The available specimen is a deformed outer cast with a few elements of the ornament. This preservation does not permit a reliable species identification. However, the form is characteristic enough to suggest a group of possible relatives. Distribution in Kachchh — Wasthawa Formation (Upper Callovian), Wasthawa section, Wagad Dome. Order doubtful Superfamily Nerineoidea ZlTTEL, 1873 Family Tubiferidae COSSMANN, 1895 Genus Ceritella MORRIS & LYCETT, 1851 Ceritella sp. (Plate I: 7-9) Material — A single specimen. Measurements H HL BHU2001I50 13.0* 3.5 Description — High turriculate, small (juvenile?) shell, without apical part and peristome. Whorls separated by canaliculate suture. Earliest whorls flat, subsequent ones with spirally swollen upper (subsutural) belt (= outer spiral fold); remaining part feebly concave below fold then convex. Peripher}' rounded, base convex and anomphalous. No internal fold observable. Distinct growth-lines not visible; elements suggest opisthocyrt sinus on spiral fold, HP D WP AA AL 3.0 3.0 2.5 remaining part seems to have orthocline orientation. Remarks — No clear match was found in the literature. The available, incomplete, small shell may be a juvenile form therefore species attribution has been postponed while more specimens could help identification. Distribution in Kachchh — Lower Callovian Gadhada Formation, N of Mouwana village, Mouwana Dome. Family Nerineidae ZlTTEL, 1843 Genus Turbinea PCHELINCEV, 1965 Turbinea khadirensis n. sp. (Plate I: 1-6) Holotype — BHU2001I 51 (Plate 1: 1-2). Type locality — Khadir Island, Kachchh, State Gujarat, India. Type strata — Hadibadhang Shale Member of Khadir Formation, Bathonian. Species name — From the name of Khadir Island. Diagnosis —• High turriculate, telescope-like shell with concave whorls. Diameter of whorls at upper and lower suture (nearly) equal. Suture runs on sharp keel, being peripher)- of previous whorl. Aperture axially elongated, quadrangular; sharp inner spiral fold of triangular cross-section terminates at angle of parietal wall and columella. Low, rounded second fold on columella at onset of short siphonal outlet. Material — Fourteen shelly specimens, all damaged. None with earliest whorls preserved.
