«From the fine, gray clay on the Tabaquite Road we have a right valve of the Pecten cercadica group; but differing from the Brasso valves in having much flatter and weaker ribbing and a very much sharper byssal notch.
This valve is compressed, somewhat oblique, delicate, with sixteen ribs that become v/eaker posteriorly so as to be hardly more than undulations. The ribs extend to the beak. The anterior ear is slightly the smaller and has six radiating threads, the upper being the coarser and more scabrous. Byssal notch deep, nearly, but not quite, half the length of the ear, very sharply V-shaped. The posterior ear is smooth except for fine growth lines. Length of valve 30, altitude 29 mm. This valve resembles P. vaughani var. flabellum Cooke, but in that Cuban shell the ribs do not extend to the beak and the byssal notch is U-shaped, while in this the ribs reach the apex of the beak and the notch forms a very sharp, deep angle. Locality.— 8½ miles on the Tabaquite Road near the Tabaquite oil field. Horizon.— Lower Miocene, about equivalent to the Tamana horizon.» CARLOTTA JOAQUINA MAURY, 1925

«Pecten cercadica var. tabaquita Maury, 1925a, from the Tamana Formation in Trinidad, is not a subspecies of Pecten cercadica (assigned in the present study to the decatopectinine genus Antillipecten n. gen.), but rather is a Leptopecten. Because it is represented by only a single, rather poorly preserved right valve (PRI 898, the holotype by monotypy), it is difficult to compare reliably to other species. Nevertheless, it appears to be less prosocline and has higher ribs than L. thompsoni and L. maturensis. The specimen described by Maury (1925a: 87) as Pecten cf. cercadica, from the Brasso Formation of Trinidad (underlying the Tamana Formation), is another Leptopecten and is possibly the same species as that in the Tamana Formation.»
